The RoboClaw motor controllers from Basicmicro (formerly Ion Motion Control) can control a pair of brushed DC motors using USB serial, TTL serial, RC, or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system. This version can supply a continuous 7.5 A per channel (15 A peak).

 

Key Features

  • Simple bidirectional control of one or two brushed DC motors, depending on controller model
  • 6 V to 34 V or 10.5 V to 60 V operating supply range, depending on controller model
  • 7.5 A to 120 A maximum continuous current output, depending on controller model
  • Dual-channel controllers support channel bridging to allow control of a single motor with double the current capability
  • Automatic current limiting reduces duty cycle when temperature exceeds 85° C
  • Four communication or control options:
    1. USB serial interface (virtual COM port)
    2. Logic-level (TTL) serial interface for direct connection to microcontrollers or other embedded controllers
    3. Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller
    4. Analog voltage (0 V to 2 V, 5 V tolerant) interface for direct connection to potentiometers and analog joysticks
  • Dual feedback inputs for PID closed-loop control:
    • Speed or position control with quadrature encoders, up to 19.6 million encoder pulses per second
    • Position control with analog encoders or potentiometers
    • (Open-loop control with no feedback also available)
  • Screw terminals for quick connect/disconnect
  • Configurable via pushbutton interface or USB connection and PC software
  • Regenerative braking
  • Tolerates high-speed direction changes
  • Jumper-selectable 5 V BEC
  • Battery monitoring and under-voltage cutoff protects batteries from over-discharging

Sample Code

Basicmicro has written an Arduino library for the RoboClaw that makes it easy to interface these motor controllers with an Arduino. The library comes with several example sketches that demonstrate different methods of controlling the RoboClaw.
