TinkerCAD costs $19 per month for the Personal edition and $100/month for the Startup edition. I'd buy a basic CAD package rather than "rent" one month to month. Three-dimensional printers might appeal to more people at a lower cost, but as the cost goes down I expect more small companies to offer 3-D printing services--perhaps even the UPS Store or local Kinkos-Fedex store could make my prototypes.
I no longer make my own printed-circuit boards because I can get a 2-day turnaround from local shops that welcome small orders. And some PCB quick-turn companies also provide the schematic-capture and board-layout tools for free. Watch the same thing happen with 3-D printing.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
