Master's Thesis: Robotic Screw Driving

Help a humanoid robot turn a screwdriver. In this master's thesis at 120ft, you will compare approaches to robotic screw driving, then design, build and validate a working prototype. Host: 120ft Factory AB, Stockholm Company supervisor: Hsiu-Fang Chien Field: Mechanical and electrical design, mechatronics Background 120ft builds Factory OS for humanoid robots, currently the Unitree G1-D, doing high-mix, low-volume assembly. The current Dex1-1 parallel-jaw gripper cannot reliably align and drive a screw, and there is no dedicated solution for it today. Several directions are plausible: a handheld screwdriver the gripper picks up, a dedicated end-effector with swappable bit heads, or a screwdriver mounted on the arm or wrist. Each brings different trade-offs in mechanical complexity and how much it limits the gripper's other uses. What You Will Build

• Compare solutions. Evaluate at least these three approaches against criteria including fastener and thread size range, minimum torque and axial force, wrist or arm adaptor needs, and position precision and accuracy. Choose a direction with reasoning the supervisors can follow.
• Design and build. Develop a working prototype of the chosen solution with its own power source and a microcontroller-based control interface.
• Validate under teleoperation. Drive the robot through the screwing sequence and demonstrate repeated, reliable use of the tool.

What we provide

• A technical supervisor.
• Access to a real Unitree G1-D.
• Workshop and prototyping support as available.
