  • DFRobot 4.8-46V, 2A Dual Motor Controller
    Works great!
    Review by Richard
    Even when running near the rated current limit, the driver works great. The heat sink was an excellent addition to the l298

  • Arduino Compatible Mega Motor Shield 13A, 5-28V
    Robust and Easy to Use
    Review by Ruslan
    Robust, reliable and easy use shield.
    Comes with a user manual which is very helpful.
    The speed and direction of each shield is easily controlled by two digital pins of the arduino board.

  • 10A DC Motor Driver Arduino Shield
    Great Product
    Review by lmcdima
    I bought 4 boards (2 using and 2 spares) for a actuator driven flight simulator (Firgelli and bought here at robotshop). The actuator normally works at 5A but under heavy load it can spike to 8A. The board works as expected, very very easy to code and minimum effort to make it part of your project...

Programming DAQs using FlowBotics Studio & FlowStone

Posted on March 14, 2014

By Carl Owen & filled under Electronics, Software and Apps.

  In this tutorial we are going to cover Data Acquisition boards (or DAQ’s as they are better known) and how to program them using FlowBotics Studio which uses the FlowStone graphical programming language inside. Data acquisition devices form the basis of most robotics systems obtaining signals in and out of a system from external [...]

Robot Reverse Engineering: Designing an Autonomous Transatlantic Boat

Posted on March 06, 2014

By Jeffrey Arcand & filled under Entertainment, Robotics Projects & Kits.

Some of you may have hear about Scout — The Autonomous Transatlantic Robot. She is a 12-foot long robotic solar-powered boat designed and built by 7 college/university students from the USA. She was launched in August 2013 from Rhode Island and programmed to autonomously cross the Atlantic Ocean to her destination in Spain. Although she [...]

Arduino Microcontroller Feature Comparison

Posted on May 14, 2012

By Coleman Benson & filled under Industry.

Arduino is fast becoming one of the most popular microcontrollers used in robotics.There are many different types of Arduino microcontrollers which differ not only in design and features, but also in size and processing capabilities. In this article, you’ll understand the differences between the Arduino Microcontrollers (as of 2012). There are many features that are [...]

Basics: What is a Motor Controller?

Posted on February 20, 2012

By Coleman Benson & filled under Where to Start.

A Motor Controller is a device that acts as intermediary between your robot’s microcontroller, batteries and motors. A motor controller is necessary because a microcontroller can usually only provide roughly 0.1 Amps of current whereas most actuators (DC motors, DC gear motors, servo motors etc.) require several Amps. The current a motor consumes is related to [...]

By Coleman Benson & filled under Arduino, Robotics Projects & Kits.

About Arduino Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other [...]

Without the specs of the PWM signal, it's hard to say.
The two servo controllers you mention are for standard R/C servos, so some adapting would be needed (at least for the connector).

I've spent quite a bit of time looking at the various Arduino examples for the RoboClaw motor controllers. I am thinking seriously of going right to running it in Packet Serial with all the encoder options rather than using simple PWM first. I never really did like using PWM for motor control.

Hi Carlos,

Thank you for the quick reply.

Our PLC has relay output, not PWM output.

Do you have any controllers that we can program in the speeds, accells and decells into it and just give it input signals?


Thanks,
