Motor Controller Problems
• Inadequate current output
• Complicated interface
• Outputs only allow for one motor
Problems with some of the controllers considered
Sizing the power supply Communicating with the microcontroller

Track & Wheel Research• Alternatives to the $45.00 8020 Inc. wheel and bracket combo were researched.• Option 1: Drawer slide C-bracket combined with fitted steel castor wheel • Option 2: Creation of custom wheel and bracket combination to fit 8020 Inc.
1010 aluminum profile cutout. • Option 3: Stay with current selection.

Pulley & Cable Research• Plastic pulleys of an acceptable diameter were found at The Home Depot.• The removal of pulley from the bracket
is possible in order to stack pulleys as needed.• A mount and axel assembly can be created in order to adapt the pulleys for
the prototype.• A plastic sleeved steel cable with an acceptable cross-sectional diameter was found to fit the pulley, basic friction tests were performed to ensure that the cable can grip the pulley.
