Re: Different Types of robots
Jim is right about ball control. We have 16" PVC rings that grab the ball, using 2 1.5" pneumatic cylinders. Our shooter is a linear mechanical punch with 240 lb pulling force, retracted by an original steel cable mechanism. Also, my thoughts on playing defense:
We didn't plan to play much defense at our UNH district event with our mecanum drivetrain. We have a creative auxiliary drive in the works, but it wasn't ready for UNH.
When we got there, we usually took the role of inbounding/truss robot. This required us to play a lot of hard defense. Much to our surprise, our 108 lb mecanum machine managed to defend and shut down alliances with 6-CIM tank driven scoring robots.
TL;DR: You don't need to build a robot built purely for defense to play really good defense.
