Objectives: Design and build a simple robot that traverses a horizontally stretched rope.
Gear box design
Solidworks Motion Analysis
I laser cut the chassis and arms and assembled the gear train and electric circuit from stock parts. For gen 2.0 I would redesign three critical features: 1) avoid double jointed knees, 2) stiffen claw connections, 3) use shoulder bolts for all joints for higher precision.
I designed a robot whose arms grab a horizontal rope one after another, pulling it along. Locomotion occurs as each arm pulls the robot forward. The motor is a simple brushed electric motor, geared down 280:1.
