Servo Control is a actuation capability that positions a shaft to a specific angle using PWM control.
Overview
This is a stub page. This capability is not yet implemented in any BRS robot. This page exists to:
- Document the concept for future implementation
- Invite community members to add it to their robots
- Provide a starting point for hardware selection
What It Controls
Angular position (0-180° for standard servos)
Common Hardware
SG90, MG90S, MG996R hobby servos
Enables Activities
Adding this capability to your robot would enable:
Technical Considerations
- **Advantages**: Built-in position feedback, no additional driver needed, easy to control
- **Disadvantages**: Limited rotation (180° for standard), not continuous rotation
- **Typical cost**: $2-15 depending on torque
- **Interface**: PWM signal (50 Hz, 1-2ms pulse width)
- **Torque**: 1.5-20 kg·cm typical
- **Speed**: 0.1-0.2 sec/60° typical
Contributing
Want to add this capability to your robot? Here's how:
- Select appropriate hardware (see "Common Hardware" above)
- Mount the hardware to your robot chassis
- Wire to your microcontroller
- Write driver code or use existing libraries
- Test and calibrate
- Document your implementation
- Update this page with your findings
- Share on Discord
