Dome Drive — Classic Roam-a-dome

The Roam-a-dome integration uses an RDH serial position sensor to track dome angle. Unlike the RoboClaw encoder drive, it doesn't require an encoder motor — the position sensor reads dome angle directly.

Hardware

  • Roam-a-dome (or compatible RDH serial) position sensor
  • Connect to the serial header configured for RDH_SERIAL in drive_config.h

Configuration

Enable in drive_config.h:

#define RDH_SERIAL Serial2

Dome commands (home, random, go-to-angle) are passed through to the RDH device via serial.

Capabilities

  • Home positioning
  • Random seek mode
  • Absolute angle targeting

Position feedback comes from the RDH sensor rather than encoder ticks.
