Anti-backlash Gear

In competition robotics, externally geared mechanisms requiring precise movements are a universal necessity seen in nearly all robots. Getting accurate rotational data from these is one of the keys to effective autonomous movement. However, spur gears include a clearance between the mated gear teeth which is a necessary feature that allows for proper movement of the meshing gears. We have developed a solution in the form of a simple two-gear assembly that passively compensates for this backlash.
