Motors & Actuators

Motors and Actuators make your projects move! Some actuators are better suited for specific tasks, others can be adapted by mechanical edge to create the rotation or motion needed.

  • 7.2VDC 291RPM 11oz-in GHM-03 Spur Gear Head Motor
    Ignore previous review.
    Review by Sasan
    I meant to review GHM-13 not GHM-03.

    The GHM-03 are not good for Rover in Tanking situations. Recommend GHM-13 for Rover over what is normally shipped with Rover.

  • 7.2VDC 291RPM 11oz-in GHM-03 Spur Gear Head Motor
    Worked as exepected with higher torque
    Review by Sasan
    Rover had trouble tanking with motors with lesser torque. These motors with 50:1 gear ration and higher torque achieved Tanking while other motors failed. Recommend these motors instead of what is sold with Rover. RPM not that important compared to stall performance and tanking.

  • Banebots RS-550 Motor 19300rpm 12V 70.55oz-in
    Very happy with motor!!!
    Review by Richard
    I replaced a couple of HPI GT 550's with this motor and could not be more pleased thus far. I was only getting about 1-2 weeks use out of the HPI's before losing a brush holder. These have already outlasted the HPI GT 550's by twice as long and still going!!

  • 9g Continuous Rotation Micro Servo
    Nice but unstable
    Review by Greg
    Tiny and speedy, but impossible to get a steady stop position set, it drifts all over the place. I am going to have to add a relay to shut off power to the servo when I want a full stop out of it.

  • HS-5645MG Digital High Torque Servo Motor
    Great Servo lots of torque
    Review by thomas
    Very High Torque for a nice small sized Servo Motor works great

Robot Construction Kits

Posted on April 23, 2014

By Coleman Benson & filled under GoRobotics >> Education, Robotics Projects & Kits, Where to Start.

Robot Construction Kits can be distinguished from normal robot kits since they use modular parts and allow you to assemble different robots using the same parts. A robot kit on the other hand only allows you to build one robot. Robot construction kits are a great investment because they tend to include everything you need [...]

Barobo Actuator Disassembly

Posted on February 19, 2014

By Coleman Benson & filled under Electronics, Mechanics, Tutorials.

Barobo‘s Linkbot all-in-one smart actuators allow anyone without any knowledge of robotics to create and “program” robots. Each actuator is packed with many features including: • Atmel AVR Microcontroller: Compatible with Arduino so you can re-flash with your own firmware using the on-board bootloader • ZigBee-Capable Radio: Communicate wirelessly with an 802.15.4-compliant radio, create mesh [...]

Full Metal Dalek, Fiction Meets Dedication

Posted on September 19, 2013

By Carlos Asmat & filled under Entertainment.

Making replicas of robots seen in movies is not uncommon and there are many replicas of R2D2, Wall-E and Jonny 5 to name a few. Many of these incorporate a high level of detail while being faithful to the original robot’s look and feel. However, most of these replicas do not match (or at least [...]

Robot Arm Torque Tutorial

Posted on February 28, 2013

By Coleman Benson & filled under Dynamic Tools, How To Make a Robot, Mechanics.

This tutorial is intended to complement the Robot Arm Torque Calculator found in the Dynamic Tools section of GoRobotics. The equations used in the calculator to determine the torque required at any given lifting joint (raising the arm vertically) in a robotic arm are presented here. Note that the term “actuator” is used rather than motor because [...]

... is also shield compatible, so you can add all the shields, sensors, and actuators that you can normally add, except those that use pins 5, 6, 7, or 8 because those pins are used to control the motors.

Relays alone would do the job - so long as they can handle the current. Motor drivers / controllers are best for variable speed and/or automatic control.

Some joysticks have a spring return (usually used on the throttle) while others remain in their last position. For a "cruise control" you could use joysticks which do not have a spring return. Just an idea.
