Overview
A versatile 6-DOF mechanical arm in full metal alloy construction. This kit bridges the gap between educational toys and professional platforms — six degrees of freedom in a rigid metal frame at an accessible price point. Available in 13 variant configurations from bare frame to fully assembled.
Six servo motors require external power supply (6V 2A minimum). Do not power all servos from Arduino USB. Secure base to work surface before operation. Keep workspace clear during movement sequences.
Key Features
- 6 Degrees of Freedom — Complete articulation for complex manipulation tasks
- All-Metal Alloy Frame — Aluminum alloy construction, not plastic
- 13 Variant Options — From bare frame to fully assembled with controller
- Servo Motor Drive — High-torque servos on all joints
- Mechanical Design — Proper linkages and bearing points
- Programmable — Full Arduino/RPi control via PWM servo signals
