By using the GamePad to control the arm with could lift it and return it back. The main problem with controlling the arm is that if you just use the motors you would hit the robot, bend the axles and breaks the gear wheels. We would use the distance sensor to make the arm move without hitting the robot.

Control the hand of the FIRST Technical Challenge Push Bot robot with the GamePad bumpers.

How to control the arm of the push bot using the two triggers on the GamePad of the FTC Push Bot? 

This third way of positioning the LEGO Mindstorms EV3 motors on the robot seems to be the most productive with the most advantages. We have named it "correct", but we completely understand there might be other even more efficient ways to position the motors on the robot.

Based on a request we are showing the robot construction with two rear motors instead of a differential. In this way, as a construction, it is closer to more students, but much more challеnging for programing. 

The LEGO Mindstorms EV3 set comes with two LARGE motors. But even though these motors look almost the same they are not quite the same. There are always some differences in their behaviour. If you have more than two motors, because you bought them or you won them somewhere at a competition, it is worth doing an experiment to find which pair of motors works best. 

Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.

Once you start turning how to do you a whole 180 degrees turn. The robot almost does it, but not completely

Why we will never use seconds in our lessons.

In this episode we combine in a single program the previous two programs for moving forward and backward. 

Conenct the motors of the VEX EDR motor to the VEX Corted Controller. For connecting we need the motor drivers.
