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.
The tutorial is about what are the parts that you should buy to have the Ball Collecting mechanism.
The robotics tutorial is about the shape of the pipe its advantages and disadvantages.
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 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
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.
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.
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
Take the hacksaw, the drill and let's cut the pipe.
Building instructions with dimensions on the ball collecting mechanism for the FIRST Technical Challenge Push Bot. The collecting mechanism should be attached to the Chassis - https://www.fllcasts.com/materials/382-ftc-push-bot-chassis-from-tetrix

Building instructions for a LEGO Mindstorms EV3 Robot that we call the Five Minute Bot because it could be built in Five Minutes.
Note: If the robot is making inconsistent turns due to the floor, modify the castor wheel so it is placed further back in the construction. Thus the center of mass falls more over the tires and the turns are more consistent.
Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.
For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
Building instructions for the Easy Bot built with LEGO Mindstorms EV3 parts. This LEGO robot is suitable for classes with students in robotics and is one of the first robots that we build. It takes about 10-20 minutes to be constructed by first-time participants.
Building instructions for a LEGO Mindstorms EV3 Robot that we call CastorBot, because it uses the castor ball.
This is a blueprint of dimensions of the FTC 200 mm axle.
