I spent most of my time designing the front wheel assembly and the section of the chassis that handles steering. To give the rover directional control, I placed a servo motor right above the front motor. Designing and iterating on this steering mechanism took up a significant chunk of time.

First, I modeled the main motor assembly that integrates into the front end. From there, I focused on refining the pendulum suspension system, tweaking several parts that weren’t fitting or looking exactly how I wanted. I also created the small connector joint that links the pendulum to the main control arm, which will eventually balance both sides of the suspension. I haven’t mirrored the geometry to the opposite side yet, but that’s the immediate next step.

Once the CAD is finalized, the next phase is importing the model into Blender to rig it and simulate the exact mechanical movement using Forward and Inverse Kinematics (FK/IK).
