OpenQDD - 3D-printed open-source robotic actuator
The author designed this robotic actuator to be a powerful, easy-to-build, and relatively inexpensive solution to creating dynamic robots. Robots like Spot, Atlas, and the MIT mini cheetah easily impress the eye with their agility, speed, and overall ability to mimic natural motion. With OpenQDD, creating high-performing actuators at an affordable price is possible.
Features:
9:1 Planetary Gear Set
Helical Gears: 25° Helix Angle, Low Backlash
ODrive S1 FOC Controller with an Onboard Encoder
Air Vents for Passive Cooling
Peak Holding Torque: 16.36 Nm
Total Mass: 935g
13 3D-Printed Parts
Total Cost: $247
The actuator uses a 90KV Eagle Power BLDC Motor as well as an ODrive S1 FOC controller. In closed-loop control mode, the S1 allows you to control the position, velocity, and torque of a brushless motor.
