Our arm design has the shoulder joint at a fixed location offset towards the back of the robot. In its starting configuration it should be about 55" long and after extension it should be 64" long. I am looking into using pneumatics for the extension but many members on my team want to use a threaded rod hooked up to one of the banebot motors.


Our material for our arm is 1" aluminum tubing with 1/8" thickness which is a little heavy duty for what were using it for but it's whats left over after we build the frame to support the arm.


Instead of mounting the large sprocket to an axle could we mount our two large sprockets directly on the arm by drilling holes through the sprockets and bolting it directly onto the aluminum tubing?
