Position-correcting system gives a CNC-like ability to handheld tools.
Alec Rivers, lan E. Moyer, and Frédo Durand of MIT have created a sort of GPS for handheld power tools. A small screen shows the user where to cut, and motors help guide the tool in the correct direction. The user just has to guide the tool in approximately the right direction.
The result is something related to CNC. The advantages are lower cost and increased portability, but it lacks the full automation of a CNC router. Watch the video below for a look at how the system works.
