You can specify any name for the collision in this field. Any part used in the model can function as a motor. Ideal parts would be axes, manual cranks or gear wheels. First, you need to select the part that is to act as a motor. After activating this function, a window will open with the parameters to be set.
In the background of the 3D window, only the selected part is displayed which already carries out the movement corresponding to the settings in the window. Function Settings Rotation Axis Using these three buttons, you can determine the axis around which the motor is to rotate.
That axis is already embedded in the part and will, therefore, be correctly displayed. Status The status determines the condition of the motor directly after the start of the kinematics mode. The arrow pointing to the right causes the motor to carry out the clockwise rotation. The arrow pointing to the left starts the counter-clockwise rotation.
The button in between stops the motor from running for the moment. This is 32 usually advantageous when working with the Logic Manager because the rotation of the motor is controlled in that mode. Motor In this field you will select the number of the motor. There is currently a maximum of 8 motors available. It allows you to rotate and move both individual parts and entire groups of parts. First, you select a part and then open the Coordinate Manager.
The status bar will always reflect the name of the selected part. With the help of the individual buttons, you can now move the part along its coloured axes or have it rotate around those. In addition, you can also choose the pivot point to control your rotation. Normally, the rotation always takes place around the centre of the part. If you wish to rotate around a different spot, you can use any of the connection points of the part selected.
Position Moves the part along its red axis by 0,5 mm Moves the part along its red axis by 5,0 mm Moves the part along its green axis by 0,5 mm Moves the part along its green axis by 5,0 mm Moves the part along its blue axis by 0,5 mm Moves the part along its blue axis by 5,0 mm Rotation Rotates the part around its red axis by 1 degree Rotates the part around its red axis by 10 degrees Rotates the part around its green axis by 1 degree Rotates the part around its green axis by 10 degrees Rotates the part around its blue axis by 1 degree Rotates the part around its blue axis by 10 degrees In addition, clicking on the 90 button allows you to rotate parts by 90 degrees.
A hose consists of a multitude of supporting points connected through a Bezier algorithm so that the hose does not appear angular. Since placing the supporting points within a single 3D window is too difficult, you will, for the first time, 34 get a four-sided view.
This means you will view the model from 3 different perspectives side view, front view, top view as well as in the regular 3D window. Procedure: First, you will need to create a new hose by clicking on the button with the green plus sign. A menu will open listing the various types of hoses. After a hose e. You will now select a type of view and, clicking the left mouse button, insert new supporting points.
Once you insert the second point, the hose already becomes visible. Help Activates the help function for the item selected. Back Terminates the Hose Manager. Using these 5 buttons, you can switch between the individual views: 1. Side view 4. Top view 5. Front view Note: You can easily switch between the individual views using keys 15 on your keyboard.
Switch Front-Rear Clicking on this button allows you to switch the camera from front view to rear view and vice versa within the 3 viewing options. This way, you can view the model both from the front and the rear.
Within the 3D window, the rotation mode is permanently active. Here, keeping the left mouse button pressed, you can rotate the camera around the model.
Keeping the right mouse button pressed and moving up or down will zoom the camera. This works similar in the 3 other viewing options except that the model is not rotated but the section is shifted.
Move Supporting Points In this mode, you can individually move the supporting points of a hose within the viewing window. In doing so, the individual supporting points are represented by 35 white balls. After you have selected a ball using the left mouse button, you can move that supporting point. During the movement, the selected supporting point is displayed in black. Insert Supporting Points Using this mode, you can insert additional supporting points into the hose.
First, you need to select a hose. Then you can insert a new supporting point within a viewing window using the left mouse button. To create a visible hose, you must insert at least 2 supporting points.
When it is turned on, the supporting points can no longer be placed randomly, but they are bound to a predefined grid. If you press this button a little longer, a menu will open from which you can select the graduation.
The values that are available range from 0,25 to 10 mm. Insert New Hose This function allows you to create a new hose. After you have selected this function, a menu will open displaying the various types of hoses. You can choose from pneumatic hoses blue , tackles white , and red or green cables. To do so, you first need to highlight either a hose or a supporting point. Move Supporting Point Up A hose always consists of a series of sequentially numbered supporting points.
This function allows you to move a highlighted supporting point further towards the beginning of the chain respectively, further up. You will need to apply this function to insert an additional supporting point within the chain. Move Supporting Point Down This function allows you to move a supporting point further towards the end of the chain respectively, further down. After the Manager has been activated, all animated parts are listed one below the other, along with a time bar.
On the time bar, each time key is displayed with a blue circle. You can select the individual time keys using the left mouse button. Keeping the left mouse button pressed, you can move the selected key within the time bar.
The right mouse button allows you to open a menu where you can delete the key you just selected. Back Terminates the Time Manager. Zoom In This function enlarges the view of the time bar..
Zoom Out This function reduces the view of the time bar. The Light Manager allows you to turn those light sources on or off. The 2 nd light source has a special function as its position always equals the position of the camera, resulting in a balanced lighting of the model. All other light sources are turned off by default and are usually not required.
With this function, the active light sources and their positions are exported as well. This allows you to create better shadowing effects. The dialogue window is divided up into three tabs one for the bindings, one for the motors and one for the collisions.
To the right, you will find two buttons, one for editing and one for deleting. The list is made up of 3 columns. When you select a binding using the mouse, the two parts involved are displayed as selected in the 3D window.
The Edit button on top allows you to edit the selected binding except for the firm binding since it has no parameters. Using the button below, you can delete the selected binding. Motors The second tab lists the motors a maximum of 8. The Edit button on top allows you to edit the selected motor.
Using the button below, you can delete the motor. Collisions The third tab lists the collisions of the current model. The list is divided into 3 columns. The first two columns display the parts involved. The third column reflects the number of the motor that reacts in case of collision. When you select a collision using the mouse, the two parts involved are displayed as selected in the 3D window.
The Edit button on top allows you to edit the selected collision. Using the button below, you can delete the selected collision. The setup of the Logic Manager resembles LLWin or rather RoboPro, so users who are familiar with one of these programmes do not need any training.
Basically, the Logic Manager works in two different modes. The buttons on the right enable you to switch between the two modes. Using the left mouse button, you can move the blocks within the window. When you click the right mouse button on a block, a menu will open where you can delete the entire block or the closest link. A double-click on a function block allows you to set its parameters see below.
Connection Mode In this mode, you can link function blocks among each other. First, you need to click the left mouse button on a connector of a function block. Holding the left mouse button, you will now select the second connector and then release the mouse button.
Generally, connections can only be established from exits to entries. Example of a logic procedure The example, above, shows a simple logic procedure which first starts motor 1 in the clockwise direction. The last step ends the programme. Start Block The Start Block always starts a new process. More than one process can exist at any time without a problem. Therefore, it is, for example, possible to realize totally independent processes. The additional realization of a flashing light process is a 39 typical example.
The number of possible processes that can run at the same time is limited only by your PCs computing power. The Start Block has no parameters. End Block The End Block terminates a process. This does not mean, however, that the kinematics mode is terminated as well. The End Block is not absolutely necessary as many processes run endlessly and would never reach the End Block. The End Block has no parameters. Motor Block Using a Motor Block, you can start or stop one of the 8 motors and select their rotating direction.
The parameters allow you to choose from the following settings: Motor No. This means that the programme may continue at two different spots, as determined by a collision. If the selected collision takes place, the programme will continue at the connector with the green dot. Otherwise, it will continue at the connector with the red dot.
Pause Block The Pause Block allows you to interrupt the programme for a set period of time. Once that period is over, the programme continues. You can set the time within the parameters. The entry has to be in milliseconds.
Part Colouring Block This block allows you to set the colour of a construction part. In general, this function is only used for flashing light controls. These sets use similar models and incorporate more components to the design to make it more complex.
Check out some of the manufacturing mechanisms exhibited in these sets, and realize new ways of understanding and teaching building concepts.

Identifying the drive gear is critical in any system. Gears turn in a circular direction. There is a relationship between torque and speed in gearing. A ten-speed bicycle has ten different gear selections. When you pedal up a hill, you use a gear train that provides more torque turning force but, in doing so, less speed. When you pedal on flat land, you use a gear train that provides more speed, but in doing so, less torque within the gear train.
The gear train in which diagram provides more torque? Fill in the diagram below to show the relationship between torque and speed in gear trains. More torque less speed More speed less torque 3. Complete the chart below showing the relationship between drive gear and driven gear in a simple gear train.
Driven Gear Size To increase torque larger than drive gear To increase speed smaller than drive gear 4. Calculate the following gear ratios. Conclusion 1. What would cause the gears to lose some of their efficiency? Friction is one of the keys issues. There are two areas of friction to be concerned about: gear teeth friction: the teeth of the gears grind with another gear or a chain gear set: what the gear is fastened to.
On a bike, the gear is placed on a ball bearing set that will corrode in time. Gear system alignment is another issue. The teeth will grind more if the gears are not perfectly aligned with one another. How could the effect be minimized? Oil and maintenance. The pictures given in the activity are awful. This document and has been added to Appendix C to this book. Finally, there is a question I would suggest to add to the Conclusion. Add which gear assemblies change the direction of motion.
The question is listed as 4 below. Which gear assemblies increased speed? Which gear assemblies increased torque? Which gear assemblies allow the reversal of power? Pulley and Belt Simple Gear Train 4. Which gear assemblies allow the direction of momentum to be diverted?
Simple Gear Train 8 It is not just difficult since students will come up with various solutions, but the directions in some are not clear. In each task a suggestion of a build. On the PLTW curriculum, it says this activity is suggested.
But in fact, this is where the students can really be creative in their solutions and not so prescribed. There are photos in Appendix E of previous builds that may help give a few ideas and suggestion. Task 1 — 4 wheel drive vehicle Task 1: The scientists and doctors need a vehicle that will take them over the rough terrain to search for other survivors and collect data. Needs to travel over rough terrain. Needs to have a universal drive shaft.
Must be able to switch from two-wheel drive to four-wheel drive. One of the biggest questions posed was how to be able to switch from two to four wheel drive. Task 2 — Solar Collector Task 2: The scientists need a machine that will rotate a solar collection dish from inside their labs, but be located outside their building and around the corner. Needs to have a minimum gear ratio of Needs to be located around a corner.
Needs to be angled 30 toward the sun and be able to follow the sun. One of the first questions was about the corner. The corner makes the contraption use different angles and multiple pulleys to reach the corner required. As a suggestion, use either the surgical tubing or string to use as a connecting wire. Task 3 — Equipment mover Task 3: Doctors need a machine to move all their operating equipment and generators, at one time, from room to room. One of the pieces of equipment is an old radio now used to regulate heartbeats, called a cardioregulator.
Must move all the equipment at once. Must create a cardioregulator. The suggested build in the appendix focuses on the equipment mover. Many contraptions used a simple track and a platform to move items from one room to another. Task 4 — Multi-use pump Task 4: For all members to survive, they must have food, water, and shelter. This means pumping up water from the ground, cutting wood for building and grinding grain for flour to eat. Must create one machine that will perform all these tasks. Must have only one input to run all these devices, to save energy.
There were many questions about 3 in the instruction set above. When covered in training sessions, many of the teachers use a quarter of the baseplate as the area requirement.
Conclusion Solution 1. What would you have changed if you had time to redesign one thing on your device? There have been several comments that will routinely appear: 1. They wish they were able to use rubber bands or string. Here are a few suggests before entering the exercise: 1. Each icon represents a few details: a.
Ask the student what numbers in the icons stand for such as 0, 1, and I1. The second RoboPro icon is a light bulb that is off. Many cannot identify the object on top of the black block. For the third RoboPro icon, many students can identify the motor, but have them focus on the direction counter-clockwise. The direction of the arrow follows that of a clock. Show the opposing icon be shown later in the exercise. The opposing icons are shown in the exercise below.
Fill in the table with the possible actions you think will occur when the icons are pressed. Connected to O1 on the interface. Lamp that is on Motor running counter-clockwise at speed 8 fast. What is the advantage of using icons in programming? Icons replace the need for words and typing.
Icons are also easier to read and require a similar structure. In each exercise, the robotic setup and programming are provided. Building can vary slightly, but the programming should be exactly the same as shown. Road Trip Hints and Parts: None, very easy.

Also the electromagnet will play the role of the car, just hover it over the reed switch. Setup: Programming: Freight Elevator Challenge 20 Hints: Each floor has its own sensor and button.
Elevator will return to floor 1 after destination had been achieved. The assembly line must simulate the: Creating o the slot on the top o the slot on the side o the top hole o the chamfers on the side edges o the chamfers on the front and back edges o the side holes Painting the entire part Delivering it to the loading area at the end of the line Again, the build solutions and programming will vary greatly.
Here are few hints: 1. The piece which can be a larger block from the FischerTechnik kit 32 pg 3 should not be touched by human hands during the process. You may find a few YouTube videos showing this. Strive for no human interaction.
The use of rubber bands, links 32 pg 3 , string should be used to move the block from on workcell to another. Have the block land on a pulley, which with turn, to simulate the painting of all sides. There is still the top and bottom to paint. What would you have done to improve your workcell? Space or fitting pieces together will always be an issue. Getting the block to routinely move how the team wished is always a feat. The block is usually light and this can be a detriment. The activity covers the creation of the pump, use of the solenoids to control the air, and the compressors to push air through the surgical tubing provided.
What is pneumatics? Pneumatics is the use of pressurized gas to effect mechanical motion. How can pneumatics be used in the Simulated Factory Assembly Line that your class created? The compressed air could be used to move the block, and dry the paint. What are two advantages of using pneumatics in the Simulated Factory Assembly Line? Air is much gentler on the block than a motor pushing it. Air line is flexible and can get into tight spaces. POE Activity 4.
After using the interface for different class here are a few suggestions and updates. The activity prepares the students for the programming portion of FischerTechnik robotics. As a small note, the latest activity shows the setup for a serial connection. Just make sure to have the correct connection setting in RoboPro.
How would you change the direction that the motor will rotate?
