Device Overview

The RoboClaw is an intelligent, high performance motor controller designed to control dual brushed DC motors. It can be

controlled from USB, RC radio, PWM, TTL serial, analog and microcontrollers such as an Arduino or Raspberry Pi.

RoboClaw automatically supports 3.3V or 5V logic levels, travel limit switches, home switches, emergency stop switches,

power supplies, braking systems and contactors. A built-in switching mode BEC supplies 5VDC at up to 3 Amps for

powering user devices. In addition power supplies can be utilized by enabling the built in voltage clamping control

feature.

A wide variety of feedback sensors are supported. This includes quadrature encoders, potentiometers and absolute

encoders which can be easily congured using the available auto tune function. With sensors, two brushed DC

motors can be controlled in closed loop mode allowing precise control over position and speed. With the ability to use

potentiometers, servo systems can be created and controlled from any of RoboClaw’s interface modes.

For greater control, built-in commands are available for controlling acceleration, deceleration, distance, speed, current

sense, voltage limits and more. In addition, RC and analog modes can be congured by user dened settings to control

acceleration and deceleration rates.

RoboClaw incorporates multiple protection features including temperature, current, over voltage and under voltage limits.

The protection features are self monitoring and protect RoboClaw from damage in any operating condition. User denable

settings such as maximum current limit, maximum and minimum battery voltages are provided for more rened control.

RoboClaw’s regenerative capabilities will charge a supply battery during slow down or breaking. It’s advance circuitry can

change direction during full throttle without damage! RoboClaw also incorporates a LiPo cuto mode to prevent battery

damage.

Multimode Interface

RoboClaw’s I/O are voltage protected and can handle up to 5VDC. The I/O only output a high of 3.3V. This allows

RoboClaw to be interfaced to 5V or 3V logic easily with no translation circuits required. RoboClaw can be connected

directly to a Raspberry Pi or Arduino. All of RoboClaw’s inputs are internally pulled-up to prevent false triggers. Inputs

can also be congured using the Motion Studio application.
