In our brainstorming session my team and I had an idea for a transmission powered launcher. There would be some kind of intake on the front (still undecided) and a conveyor belt system that can store three or four balls. At the top would be two high speed spinning wheels to launch the balls.
We do realize this is an idea many teams are thinking about.
But what if we put a transmission to power those launching wheels. The purpose would be to dramatically change the speed of the wheels depending on the distance the robot is from the net. For example: if the robot was right up close to the net then it would switch into low gear as to lightly lob the ball in. But if the robot is far away then it is high gear to make the full court shot.
We have never build a compact transmission before. We would really appreciate any assistance or other ideas you more experienced players have.
I was a member of an FRC team in 2012. The general solution to changing the speed of the ball is changing the speed of the motors, without a transmission. You would simply give them less power and they would spit the ball out at a smaller speed.
Thanks for the advice, we were thinking of that too. We just didn’t know which would be more effective. We will try lowering the speed but if we try the transmission and it works well then i will let you all know!
yes you would need to slow down the motors to switch gears. It would take long though. And if you know you are going to go right up to the net and need to switch gears then you could switch while driving over
