Actually there is a big hype on KICKSTARTER dobot-m1-pro
A very inspiring idea to build an Robot-Arm in this robust way – 0.02mm repeatability and 1.5kg payload are some highlights. The company has already a successful kickstarter project behind them with a simpler construction. They looked for 75 supporter and have already 150 – Full suppported in less than one day – and there are 37 more days to go !
The concept with the changeable heads is not really new, it’s rather a trend – whats really nice is the complete and round family concept. The cost are relative low with about 1500$ – I think later it could be below 500$ in bigger quantities.
