• Creation of Mars rover for University rover competition, particularly responsible for the design and development of wheel assembly, used DMAIC lean improvement method

• Compared to the previous assembly, the new one is 20% more compact, lightweight, and convenient to assemble.

• The use of SolidWorks for modeling and Ansys WB for stress, impact, and thermal analysis of wheel assembly

Problem Statement

• The wheel assembly shall securely mount the tire and the motor to the rest of the rover.

• The motor shall be fully covered and protected from environmental hazards such as rocks.

• The wheel assembly shall have no noticeable increase to backlash between the tire and the motor.

• The wheel assembly shall have no noticeable camber effect between the tire and the u-bracket.

• Slip between the tire and wheel assembly shall be kept to a minimum.

• The motor will be disassembled without disassembling the whole assembly (from the outwards direction of the rover).

• Instances of double shear will be used in place on single shear wherever possible.
