2 & 3 Wheel Robots

To move around on the ground, you only need two motors and two wheels, which is why two and three wheeled robots are so popular. A small two wheeled robot is a great way to get started in robotics.

  • Line Tracking Robot Kit
    Great Little Kit
    Review by Ian
    I used 7 of this kit with a group of 15 kids aged 12-16 and it was a really big hit. They all worked and the kids had a blast figuring out how to best make paths for them. We explored their capabilities, raced them and the kids even developed their own robotic sumo wrestling game. I highly recommend this kit great value for the price.

Robo Sapiens: Witnessing the Evolution of the Human Race

Posted on August 28, 2014

By Mario Tremblay & filled under Cyborgs, Exoskeleton, Humanoids, Science, Sport, Wearable Technology.

  In many ways, the human race has advanced radically in a very short period of time. People born with missing limbs can now live full and “normal” lives, as can those who have suffered injuries and amputations. This is a far cry from the days when an amputated leg meant either life with a [...]

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 [...]

Posted on February 14, 2014

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

We’re always curious what our customers do with the parts they purchased. Dimitri Dekyvere was kind enough to share a video of the versatile LEGO robot he created using the new EV3 construction system along with LEGO compatible Mecanum wheels. The M3CANUM DOG is a very compact, 4WD Mecanum driven robot with sensor feedback, able [...]

Cleaning the wheel sensors would be a good idea. If you open the robot up, you might as well also clean the bumper sensors thoroughly with compressed air. They are found on the robots motherboard in two black holders. You will see a black arm moving inside the sensor ...
