  • 9g Continuous Rotation Micro Servo
    Nice Servos
    Review by Hamilton
    Used these for a robotics and Arduino class with 5th through 8th graders. Didn't really have the time or financial leeway to go the motor controller route. All went well. I'm glad these exist, I'm glad I got em' and I will do it again.

  • HS-5645MG Digital High Torque Servo Motor
    Heavy duty Servo
    Review by Ruslan
    Has very high torque. The default 90 degree HS-5645MG can be reconfigured to provide 180 degrees by digital Servo programmers such as HFP-25

  • DFRobot Micro Servo Motor
    Good to use for low strenght applications
    Review by Jeff
    Easy to use with the Servo-Motor library for the Arduino board, it lacks strenght for applications where force is apply from the plastic arms and gears.

    Never found the wiring specs. for it on the Web: the DFRobot support kindly give this to me:

    brown - GND
    red - VCC
    orange - Signal Input

New FlowBotics Apps for Phidgets Products

Posted on August 07, 2014

By Coleman Benson & filled under Research, RobotShop, Software and Apps.

FlowBotics Studio is a powerful graphical programming software which helps you easily create programs which interface with external hardware. One important feature of FlowBotics Studio is that you can also create stand-alone executable (.exe) programs which can be installed and used by others who do not own FlowBotics Studio. RobotShop, along with DSP Robotics, have [...]

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 [...]

SSC-32 Servo Sequencer Utility

Posted on October 26, 2013

By Carl Owen & filled under Lynxmotion, Robotic News.

Many of you already know the Lynxmotion SSC-32 servo control board; it’s become a bit of an industry standard as a reliable interface to control up to 32 servo motors from a single board connected to a PC. RobotShop have just released a powerful software interface to enable users to control the servo motors in [...]

Dynamixel Pro – Based “Thor-OP” Humanoid Revealed

Posted on October 18, 2013

By Coleman Benson & filled under Humanoids, Industry, Military.

When we first saw Robotis release their new line of professional (and large) Dynamixel Pro servo motors, we knew it would not be long until they were used to create larger humanoids. So, not long after their release, “THOR” was revealed; Robotis’ child-sized humanoid entry into the DARPA humanoid challenge. The latest iteration of this [...]

Thank you! I will follow up on all links.

As regards the skid turning though, I would prefer to have a single control for left/right and one for forward/back.

Isn't there any way of achieving this without having to control two motors through two joystcks?

regards,

John

To which "size" are you referring? Ideally you would look for whatever torque and speed you need, and since most DC motors by themselves provide very high RPM at very low torque, you'll need gearing to get what you calculate.
