Re: Defense: Pushing and Blocking
Last year our team perfected the art of being defensive, while still scoring major points. This year our robot is more of a tank and should have twice the torque of last year, so we'll have plenty of pushing power if need be, and the capability of holding around 50 or so balls, so score a few easy points, then push some guys around.
I'm still pushing for the pneumatic lift system. Basically like a car with an air-ride or hydraulic suspension. Build the drivetrain on a small frame, and build the rest of the robot on a seperate frame, over the drivetrain frame, supported by pneumatic cylinders. when you get where you want to be and aim, let the air out of the pneumatics, and set the actual frame down on the ground and pull the wheels off the ground. just be sure not to have the edges tear up the carpet. with all the weight, it would probably be pretty tough to push it a little. I want to build something like this in the offseason this year.
ohhohh i remember i had a picture of a chevy s-10 doing this, on air ride suspension, mono-leafed in the rear. It lays frame an pulls the wheels off the ground. i'll try and post it later tonight or tommorow...i have to find it....
