DOF
8 DOF (2 per leg)

Overview

  • Custom four-legged robot built end to end — mechanical design, electronics, and control software.
  • 8 degrees of freedom (two actuated joints per leg) for a stable, coordinated walking gait.

Design & Build

  • Mechanical: Leg geometry and frame designed in SolidWorks, driven by servo actuators.
  • Electronics: Microcontroller coordinating the eight joints with onboard sensing and power.
  • Software: Inverse kinematics for foot placement and a gait generator running the leg cycle.

Challenges

  • Keeping the body balanced while shifting weight across legs mid-stride.
  • Synchronizing all eight joints into a smooth, repeatable gait.
  • Tuning the inverse kinematics so feet land where the controller expects.

Result

  • A stable walking gait on flat ground with coordinated leg motion.
  • A full hardware-to-software platform I can keep iterating on.
