I have looked at hundreds of high resolution pictures on CD and team sites (I can't tell anything from the ones on firstrobotics.net) and I still can't answer some basic questions. For example, the most highly loaded joints should have very large diameter axles. What diameter axles do teams use and how are the axles attached to the structure. Bushings and bearings get very heavy at these sizes, what do teams do about that? Do both parts of the joint hinge freely on the axle with the drive mechanism attached seperately, or is the load bearing axle keyed, welded, bolted through, etc to transfer torque?
What I'm hoping is for some teams with particularly good manipulators to post some information on their designs.
