Hi, I'm Offiong Ansa Henshaw 👋

🎓 MSc Robotics and Automation Graduate — University of Salford
📍 Greater Manchester, UK
🤖 Passionate about Robotics, Automation & Embedded Control Systems


🔧 About Me

I recently completed my MSc dissertation designing and simulating a 4-DOF Hands-On Orthopaedic Surgical Robot with active constraint control — built from scratch using custom MATLAB kinematics, Arduino PID firmware, and Autodesk Fusion 360.

I'm actively seeking graduate roles in automation engineering, robotics, or embedded control systems across Greater Manchester and the North West.

🚀 Key Projects

🦾 OrthoSurgRes — 4-DOF Orthopaedic Surgical Robot

MEng Final Year Dissertation Project

  • Designed a serial R-R-R-R manipulator for unicompartmental knee arthroplasty (UKA)
  • Built full kinematics pipeline in MATLAB from scratch (no toolboxes): FK, IK, Jacobian, workspace analysis
  • Implemented a 5-state Finite State Machine (FSM) and active constraint law: F = −K·d·n̂
  • Arduino Mega 2560 PID firmware: 50 Hz control loop, 6 C++ modules, 4% flash / 9% SRAM
  • Step response: critically damped, settling time 1.4–1.8s, zero overshoot
  • Position error reduced from ±1.96 mm → ±0.63 mm (benchmarked vs ACROBOT & MAKO RIO)
