Follow this project to see how a robot actuator is developed with the target to be compact, cost efficient and high performance. I started with a raw scheme on existing designs and realized there is more room to play....
overview of costs:
- Motor 8308 - 50$
- Gearkit - 25$
- sliding gears for planets - 5$ (the more you buy the cheaper they get)
- one ball bearing for the main output - 5$
- cooler (not defined) 5$
- housing and cage will be printed (not defined) maybe 10$
- Mjbot Controler - 85$
Mechanical components are around 100$.
With the Controler/Encoder 185$.
Feel free to discuss
