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