Each kit is comprised of two independent drive assemblies that are mirror images of each other. Each assembly contains a right-angle worm-drive gear motor, axle and ball bearing unit, a six-inch pneumatic tire with tube, and an integrated encoder system that provides feedback to the microcontroller or processor of your choice. This kit is designed for direct compatibility with our Arlo Robot Base Kit ( 28960). It can be mounted to your own custom robot platform using the pre-tapped holes in the machined 6061 aluminum mounting blocks (-AL version) or in the pre-drilled holes on the injection molded High-density Polyethylene (HDPE) mounting blocks (-MP version). These kits are not backwards compatible with the previous Motor Mount and Wheel Kit with Position Controller ( 27971). Please see the Product Compatibility section, page 13.
