Let's attach the ball storing pipe to the FTC robot. In previous tutorials, I've shown you the complete robot, but for this, I've removed the pipe and will show you how to attach it.

Take the hacksaw, the drill and let's cut the pipe.

In this tutorial, we record an example of how to cut the pipe to the desired length with a hacksaw. Cutting with a hacksaw is very common during FIRST Technical Challenge Preparation

In this robotics tutorial, we would discuss the length of the pipe and its dimensions. These are general considerations for every container on a FIRST Technical Challenge competition. 

This robotics tutorial is about the different tools that you could use to collect the balls in a pipe on a FIRST Technical Challenge competition.

This is the task for you. We've shown you in the previous tutorials how to do it, how to use a drill and a hacksaw and a grinding stone to cut and shape a PVC pipe. Now it's your turn. Don't forget to show us pictures -> right here in the comments section

The robotics tutorial is about the shape of the pipe its advantages and disadvantages.

The tutorial is about what are the parts that you should buy to have the Ball Collecting mechanism. 

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. 

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. 

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.

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. 

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

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

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.

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

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.

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

In this tutorial, we are controlling the FTC Tetrix robot with the two sticks of the same GamePad. The left stick is for forward and backwards, while the right stick is for left and right.

In this tutorial, we would build a simple program for controlling the Tetrix robot motors with the GamePads. We use the stick and when the stick is pushed forward the motors move forward. When it is pushed backwards the robot moves backwards. 

In this tutorial, we connect the Motorola phones to the Tetrix controller using the USB hub.

We start with FIRST Technical Challenge and how you develop programs with the GamePads. It is up to you to decide how sticks, buttons and triggers from the GamePad will control the different motors of the robot and there are different decisions that you should make.
