Our robot is 129.8 lbs. I was on the suction team so I don't know much about the controls configurations, but we use a continuously variable transmission with 3 motors connected to run it. Our memorable wings are powered by 3 pneumatics: two to unfold the wings down from the sides, and one small center pneumatic to send the wings all the way down so that the suction cups slap down and become able to be activated. I think we are getting rid of the suction cups in Houston, but they were powered with window lift motors. the motors used a u-bolt to tension a bicycle brake cable. The cable runs along the wing extrusion to the suction cups, where it is connected to the inside of the rubber face of the actual cup. It pulls up on the rubber, which in turn activates the suction. However, we think that in order to increase our chain size (right now it's really small; I forget the size) we are going to take the suction mechanism off (we need the weight) and replace it with a plate of sticky tread. I have yet to communicate with Andrew about how we are going to do this, but if you're going to Houston you'll see it. I think Alex is also going to answer this thread @ some point, and she will give more controls information as she was on controls. If you have any more questions about the feature stuff, feel free to email me @ dain_kd@columbusschoolforgirls.org.
