  • RoboteQ SDC2130 - 2x20A, 7V-30V Robot Controller
    Excellent drive and value
    Review by David
    Lot's of capability and power in one small package. We needed to drive two small DC motors, so the dual output was perfect.

  • Pololu 18v15, 5.5-30V, 15A Motor Controller
    Excellent for beginners
    Review by Aron
    Packed with features, easy to use, very good for beginners. I had no experience with motor controllers before, but this controller was as nice to me as possible. Great UI, very well planned safety limits. Versatile procotols, good documentation. I'm very happy with it.

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 [...]

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 Tutorials, 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 [...]

Can't say we have come across this. Most DC motor controllers will still provide a specific voltage.
If you are using the changes in voltage to control the speed, then yes, you should read up on analog DC motor controllers.

Do you want to control it via a knob (analog) or remotely by R/C? If it's a normal DC linear actuator, we offer both kinds of DC Motor controllers - choose one which corresponds to the specifications of the actuator (voltage and current).
