A robot that can be an ATM or smart lock with color code. The programs pull in and push out the color card and play sounds if the colors are in correct order. When the order is incorrect, you hear an error sound.
The robot takes place in lesson 7 of level 3.0 Security Systems.
The block that constanlty increase the speed while turning. The goal of this is to reduce the acceleration of the robot when it starts turning so that no modules will fall.
There is only one input parameter in this block and this is the Angle on which you want your robot to rotate.
The field in the game of life could be finite or infinite. It is interesting to see and learn how an infinite field behaves and works.
One more example for an active attachment with a system of gear wheels. This time the system is constructed so that the attachment could lift heavy objects.
Calculate the number of rotations you have to do with the motor to rotate the final small 8 teeth driving gear wheel to 1.25 rotations?
You will need to attach the attachment on the 7th hole from the top on the right part of the robot as shown:
You can find the attachment here.
This is a movement module, that works like real boat paddles! It consists of two paddles, each connected to a large EV3 motor. The module can be connected with other modules to make a robot that moves like a boat!
The goal of the aircraft carrier is to launch the paper plane in the air.
At the beginning of the program the clam waits to be opened. When it feels someone is trying to open it, the shell starts closing until reaching the initial closed state and then stops moving. Most students will cope with this task very fast and will program the robot to close for seconds. Nevertheless, explain how the rotation sensor can also be used. Tell your students how much energy it takes to use a muscle for a longer time. The program is uploaded here. That is how the final program for the Clam robot should look like:
