  • 6-12V, 15RPM 200:1 Spur Gear Motor
    Excellent purchase
    Review by Dardo
    All good with my motors. It works very fine.

  • Cytron 12V 34RPM 139oz-in Spur Gearmotor
    Tough and reliable
    Review by Chris
    I used this motor in a 24x7 art installation that will run for around 90 days. Without cooling it ran warm to the touch, so I added an 80mm 12v fan. Now it's been running very cool for around 10 days. It's still sounding smooth and strong. The speed was perfect for my application, and it has much more torque than I expected.

  • 12VDC 253RPM 14oz-in GHM-12 Spur Gear Head Motor
    Now I got some speed!
    Review by Allan
    Bought these to replace the stock motors that came with the Lynxmotion tri-track kit. I found it was traveling too slow.
    The swap out was painless

    I think the motors in the kit (GHM-02) should be upgradable at time of purchase to the GHM-12.

  • 12VDC 120RPM 15oz-in GHM-02 Spur Gear Head Motor
    Reasonably priced gearmotor with good torque
    Review by robotDIY
    Tried this gearmotor on a small 4 wheels robot. The motor, while running at full speed, is surprisingly quiet. The motor also offers good torque.

  • Cytron 12V 12RPM 166oz-in Spur Gearmotor
    Excellent product for mdoel building with Meccano!
    Review by Peter
    Small size and significant torque make this DC motor ideal for a cross-section of applications such as cranes and vehicle models constructed with the Meccano / Metullas system. Being able to purchase same in Canada is a big plus for me!

Robot Construction Kits

Posted on April 23, 2014

By Coleman Benson & filled under 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 [...]

All Sciences Lead to Robotics

Posted on March 12, 2013

By Mario Tremblay & filled under Industry.

Ever since the stories of Isaac Asimov, robotics had long been restricted to the imagination. Although it had been unclear in the past, the present state of technology shows that robotics has become a tangible reality. The evolution of robotics follows the same course that was once followed by the evolution of the PC and computers. [...]

Drive Motor Sizing Tool

Posted on March 07, 2013

By RB1 & filled under Dynamic Tools.

The Drive Motor Sizing Tool is intended to give an idea of the type of drive motor required for your specific robot by taking known values and calculating values required when searching for a motor. DC motors are generally used for continuous rotation drive systems, though can be used for partial (angle to angle) rotation [...]
