Description

The RoboClaw motor controllers from Ion Motion Control (formerly Orion Robotics) 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).

The RoboClaws from Ion Motion Control (formerly Orion Robotics) are a family of efficient, versatile, synchronous regenerative motor controllers. They can supply brushed DC motors with 7.5 A, 15 A, 30 A, 45 A, or 60 A continuous (depending on the model) at voltages from 6 V to 34 V, and they allow for peak currents well above the maximum continuous ratings. The “Solo” versions feature a single motor control channel while the dual versions (denoted by a “2x” in their names) offer two channels for controlling a pair of motors.

1 Battery Eliminator Circuit

The RoboClaws have a USB interface that acts as a virtual serial (COM) port, allowing it to be controlled directly from a computer, and they feature built-in commands for controlling acceleration, deceleration, distance, speed, current sense, voltage limits and more. Several other interface modes are supported by the RoboClaw as well: it can be controlled via TTL serial for use with an embedded systems, RC hobby servo pulses for use as an RC-controlled electronic speed control (ESC), or analog voltages for use with potentiometers or analog joysticks.

RoboClaw automatically supports 3.3V or 5V logic levels, travel limit switches, home switches, emergency stop switches, power supplies, braking systems and contactors. Power supplies can be used by enabling the built in voltage clamping control feature. A built-in switching mode BEC supplies 5VDC at up to 1.2 A or 3 A (depending on controller model) for powering user devices.

The RoboClaws can be operated without feedback for open-loop speed control, or they can be used with a variety of feedback types for closed-loop speed or position control. Quadrature encoders with up to 19.6 million pulses per second are supported and can be auto tuned using Ion Studio, which is a free downloadable application. In addition, a wide range of sensor inputs such as potentiometers and absolute encoders are supported. RoboClaw’s closed loop functionality creates absolute control over speed and direction regardless of load changes.

RoboClaw incorporates several protection features including temperature, current, over voltage and under voltage limits. Several user definable settings such as maximum current limit, maximum and minimum battery voltages are provided for more refined control.

Details for item #3284

This RoboClaw 2x7A (V5B or V5C) is a slightly improved replacement for the 2x7A (V5). Specifically, the V5 linear BEC regulator has been replaced by a higher-power switching regulator on the V5B that can deliver up to 1.2 A at 5 V, and this product now includes an optional case. In all other respects, the new version is functionally identical to the previous one, though some of the components like the large power capacitors have changed, which could affect how the new controller works as a replacement for the V5 in designs with very tight space constraints. The changes from V5B to V5C are minor and do not affect performance. As of 14 Feb 2018, we are now shipping version V5C instead of V5B for item #3284.

Key Features

  • Simple bidirectional control of one or two brushed DC motors, depending on controller model
  • 6 V to 34 V operating supply range
  • 7.5 A to 60 A maximum continuous current output, depending on controller model
  • Automatic current limiting reduces duty cycle when motor current is between 1× and 2× the controller’s rated current
  • 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. 0 V to 2 V (5 V tolerant) analog voltage 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
  • 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

Ion Motion Control 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.

Note: Ion Motion Control was formerly Orion Robotics, which was previously Basic Micro. Ion Motion Control uses the following product names and number for the RoboClaw controllers:
