McNamara’s 3-Wheeled, Omni-directional, ROBOTC based ‘bot.


When you were a kid, what did you take to school with you for show-and-tell? A pet hamster? Your baseball card collection? That really cool rock that you found on your way to class (because you totally didn’t forget that today was your turn for show-and-tell)?

How about a three-wheeled, LEGO MINDSTORM based, holonomic drive robot coded in ROBOTC and controlled using a Sony PS2 controller? That’s exactly what Anthony, son of R J McNamara (, brought in for his show-and-tell.

Not only does the robot display the functionality of an omnidirectional drive (a drive that is capable of not only forwards and backwards but also side to side ‘strafing’ movement), it also shows the relative ease of coding even complex vectoral calculations using ROBOTC for MINDSTORM. Plus, the bot looks really, really cool (and is much more interesting than that boring rock anyways). Check it out at R J’s blog!
