Product Overview:
Mecanum wheels allow a robot to achieve omni-directional movement while supporting large weights. AndyMark mecanum wheels feature our patented designs. The rollers of our mecanum wheels are supported on both sides and not cantilevered.
Bengt Ilon invented this wheel concept while working for the Swedish company Mecanum AB in the early 1990's.
A Mecanum-style drive base uses 4 wheels, including 2 "right" wheels and
2 "left" wheels. One right and left is on each side of the robot. Each
wheel is driven independently, therefore a Mecanum-style drive base must
have 4 independent motors (and gearboxes, if used).
The 6" Mecanum wheels utilize 16 rollers positioned between 2 steel plates.
The 6" Mecanum HD wheel utilize 15 rollers positioned between 2 plates.
The 8" Mecanum wheels utilize 12 rollers, positioned between 2
aluminum side plates. These wheels are delivered in kit form,
unassembled.
The 10" Mecanum wheels utilize 12 rollers, positioned between 2 plates. The steel version has a tubular hub on the interior.
