As an alternative to receiving brain implants for robotic arm
dominance assistance, check out this surprisingly cheap eye-tracking solution developed by six electrical engineering students at Northeastern University. Labeled iCRAFT, for eye Controlled Robotic Arm Feeding Technology, the award-winning senior project drew its inspiration from one team member's difficulty syncing spoonfuls with the eating pace of elderly and disabled patients. Simply gaze at the on-screen box that corresponds to your food or beverage choice and the robotic arm will swing your way with grub in its grip. Ambitious DIY-ers can chase down the open-sourced software behind iCRAFT, and construct a contraption of their own for about $900 -- considerably less than self-feeding rigs living in the neighborhood of $3,500. You can catch a video of the robot arm serving up some fine Wendy's cuisine after the break.
