Dexterous Robotic Hand
Published:
February–April 2026 · Four-to-five-person team
We worked on a tendon-actuated robotic hand with 11 degrees of freedom: independent finger bending and splaying, plus wrist motion. The design used ten MG90 servos and one MG996R within an eight-week timeline and a $100 budget.
My contribution
I initially planned to work on the electrical system, then moved into mechanical design when the project needed more CAD support. This was my first experience developing full assemblies in Fusion 360.
- Built assemblies and simulated joint motion to check range of motion and mechanical interference.
- Designed and 3D printed finger and joint components.
- Helped coordinate progress across the team’s mechanical and electrical work.
Teammates handled the Arduino C/C++ control software.
What I learned
The project developed my assembly-modeling skills and taught me to adjust my role when the team needed help in another area. Motion simulation let me check how parts interacted before committing to a physical build.
Tools: Fusion 360, FDM 3D printing, servo mechanisms; Arduino for team control implementation.
