The Amber B1 is a 7-axis, all-aluminum robot arm with a 3 kg payload and 8 kg mass that Naomi Wu calls "overbuilt" for the price. It connects to a Raspberry Pi and uses a browser Studio (requires running a 'Follow' file first); hardware quality is high but the control software remains developer-oriented, with collision control and other features requiring programming. The arm is crowdfunded on Kickstarter with a $2,000 early-bird and notable delivery/component risks.
