Autonomous Vehicle Robotic Wheel Drive

The purpose of this project is to create a compact high torque/rpm robotic wheel drive for Bastian Solution's autonomous warehouse robot.

=Problem Definition=

Background
Bastian Solutions has a current WDS (wheel drive system) that uses too much space horizontally. The axial length of their current design is approximately 8 inches, with the motor contributing to most of the assembly's axial length. For their current motor to meet the required torque/rpm and power conditions, it uses a 4:1 planetary gearbox. A planetary gearbox was chosen because it has advantages over other gearboxes that work well in this application.

Pertinent gearbox advantages:

 Naturally compact, but can supply high reduction ratios (reduces WDS axial length, most motors cannot supply the required torque without modification)   Inline or coaxial design allows input shaft to be inline with gearbox (saves radial space)   Generally have low backlash (vehicle must move with precision)   The nature of their design distributes internal gearbox loads more equally (WDS undergoes high loadings)   Long life and efficiency (gearboxes are expensive to replace and they add to mechanical energy loss)</li> </ul>

For them to add more features and to further optimize the vehicle design, they must decrease the volume of the WDS. They require the WDS do be capable of meeting two primary torque/rpm conditions as well as moving a payload up to 100 lbs.
