The rocker-bogie suspension system, which was inspired by the Mars Rover, enables each wheel to independently articulate and adapt to the terrain's shape, enabling the robot to climb stairs. When working with irregular surfaces, such as stair steps, this configuration helps preserve optimum ground contact and stability. For adequate traction on risers, which are usually angled between 30° and 35°, the robot uses high-torque DC motors in conjunction with big, deep-tread rubberized wheels. The lightweight, long-lasting PVC used to make the chassis is inexpensive, easy to fabricate, and provides good structural strength for academic prototyping. By placing the hardware and power supply close to the base, the low center of gravity enhances balance and lessens the possibility of tipping.
