Tetrix

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

One of the very common tasks on different FIRST Technical Challenge competitions is to collect objects. In this case, these are colourful specifically shaped plastic object or in simple terms - balls.

There are modifications that you must do on the FTC PushBot robot. Let's discuss them

How to construct an axle with a plastic plate connected to this axle and make this plate rotate and collect balls.

How to add a plastic plate to the FIRST Technical Challenge Robot build with Tetrix. The plastic plate is for collecting the balls. The plate should rotate and should be connected to the axle.

Attach an axle to the front of the robot. Find a similar one, or modify the FTC Tetrix robot to accommodate the new axle. 

Find a plastic element. Cut it to 200mm by 140mm and attach this plastic plate to the front of our FIRST Technical Challenge Tetrix Robot.

In this robotics tutorial, we give a few notes for the teacher about adding an axle to the front of the FTC robot and attaching a plastic plate to this axle to make the robot collect balls. 

The next challenge of the course is to build a container where you could store the balls (objects) that you are collecting. The first thing is to see how it works as an end result. You can use the same principle during FIRST Technical Challenge competitions. You can also fire the balls, just by rotating the axle in reverse.
