Re: No Pneumatics?
We've used pneumatics every year (starting 2006) except 2009 for Lunacy. Pneumatics are great, they let you put the weight where you want it (the compressor can sit at the bottom center of the robot, or be moved to either end to help balance) and you can add lightweight actuators wherever you want, without having to hassle with gearboxes and extra motors and speed controllers....and limit switches, encoders, PID loops, and all that fun stuff.
Our Lunacy robot moved balls in and out with motors and rollers, it worked very well. That year we got by with only one encoder and PID loop, the rest of the motors were just run when needed.
In the end, it doesn't really matter whether or not you use pneumatics, you can make a great robot with them or without. You'll learn different things, depending on what you use. It's all good.
