1. As 548 swimmer said theres only 1 gear, but i think it was geared more for torque then anything else.
2. The original top bar is covered in sicky tape is connected to a motor (not sure which) using surgical tubbing, this way the bar stops rotating when a ball is caught under it while still keeping pressure. The middle bar is also covered in sticky tape and was at first used as a pincher bar, but didn't work very well, so now it is just more sticky tape in contact with the bar. The bottom bar is more like a ramp, also covered in sticky tape. The bottom bar is spring loaded so it can bend back while we traverse the bump. The only software i think is managing the roller is making sure the one motor continues to run
3. Not a big expert on the kicker, however there is a pull back mechinism I think is powered by a window motor, a cable runs under the robot to a pulnger that has 75lbs of force when all the springs are fully compressed. It is angleds slightly upwards to get a little lift on the ball while never kicking over the goal.
Also with regards to the comment that not blocking 469 is the best strategy... we took it a step further. When we back into the tunnel, our ball magnet and kicker face our zone and balls comming off the ball return will get possesed by us and kicked under the tunnel into our own goal.
