Project Eleven β Bipedal / Quadruped Robot
Designed a 20 cm bipedal/quadruped from scratch with 3-DoF per leg (hip, knee, ankle). Exported SolidWorks CAD to URDF, compiled to MuJoCo MJCF with tuned actuators, joint limits, damping, and stiffness. Full sensor suite β IMU + contact sensors. Stable static balance achieved in sim. Currently implementing Model Predictive Control for dynamic locomotion with real-time joint torque optimization. |
Grasshopper-Inspired Walking Robot β Sim-to-Real
Bio-inspired four-bar linkage walker fabricated from laminated cardboard β zero off-the-shelf structural parts. Ran system identification experiments to extract stiffness, damping, friction, and servo dynamics from hardware. Embedded all measured parameters into a MuJoCo physics model. Parameter sweeps + simulation-based gait optimization predicted real hardware performance within 5β22% sim-to-real error. |

Voice-Operated Mobile Manipulator
Integrated TurtleBot4 and myCobot 280 arm in a full autonomous stack. SLAM for mapping, AMCL for Β±5 cm localization, Nav2 for navigation, MoveIt2 for arm motion planning, YOLOv8 for object detection at 92% accuracy, and a speech-to-text voice command pipeline with 85% recognition accuracy in live unscripted operation. |
MuJoCo Robotic Arm β 3D Depth Reconstruction
Built a 6-DoF arm in MuJoCo with a stereo end-effector depth camera (90Β° FoV) on a linear slider. Transformed depth images from 50+ camera poses into world-frame point clouds using calibrated intrinsics, extrinsics, and forward kinematics. Fused 100k+ 3D points and executed Poisson surface reconstruction under simulated range-dependent noise. |
