Laser cutting example: Robot chassis parts

Back to more laser cutting examples.

This custom laser-cut chassis is designed to work with a pair of GM7 gearmotors and our laser-cut wheels, available from our robotics and electronics site, www.pololu.com. The cutting work consists of two 3.0" x 2.4" acrylic plates that sandwich the two gearmotors. Cross-shaped cutouts on both plates accomodate plastic tabs on the gearmotors to lock them into place securely. The bottom plate has a large hole for press-fitting a plastic ball caster, and the top plate has a rectangular hole for holding a battery pack. Various small holes for holding the plates together and attaching a printed circuit board are included.

The drawings for the two plates are shown below, followed by a cost breakdown.
