Sawppy Rover was inspired by SGVHAK Rover, a six-wheeled robot inspired by the NASA JPL rovers sent to explore Mars. The major differences between Sawppy and SGVHAK Rover were motivated by a desire to reduce cost and complexity. To accomplish this goal, Sawppy differs in two major design objectives:
- Motorization: Instead of using gearmotors with encoders managed by RoboClaw motor controllers, moving the wheels will be done with servo motors.
- Construction Method: Instead of using the Actobotics construction system, Sawppy will be built from Misumi HFS3 aluminum extrusions connected by 3D-printed plastic parts
These two major design goals can be summarized as: Servo Actuated Wheels, Printed Interconnect For Extrusion. The acronym SAWPIFE led to the nickedname "Sawppy".
