You're certainly not going to sneak up on anyone if using this LEGO motorized wheelchair. The high-pitched whine of all those tiny motors sounds like an army of robotic mosquitoes out for blood. Six of the LEGO Mindstorm bricks are used to drive the motors, with a seventh acting as the master. It's not pictured above, but there is a joystick on the right hand side which allows the rider to … [Read more...]
Seeing this device help a man get up out of his wheelchair makes us wonder why this hasn't been around for ages. The design principles behind the Tek RMD greatly benefit those without use of their legs.

[Stephen Shaffer] and his friends built it for the Red Bull Creation contest which has as its number one requirement, the need to include an Arduino. We're basically looking at a hammock frame made out of square pipe that has been put on wheels. Watch the video after the break to see the prototyping, construction, and … [Read more...]
