Dobot

From $499 (about £330) dobot.cc

What is it? A robot arm for all! The Dobot’s designers claim a whole range of uses for it: designing and building products, feeding pets, teaching children calligraphy and more. It’s remarkably accurate for such an affordable device, with a measly error margin of about 0.2mm. When’s it due? Available December 2015. Why are we excited? Although its makers insist it’s a tool for everyone, we feel it is best suited to small businesses and crafters – the type of people who need a high-precision device in their daily business life. But at its relatively low price, it’s a marvel that the designers have crammed as much into Dobot as they have.
