Unitree R1-7a
The Unitree R1-7a is a 7-axis bionic robotic arm priced from $1,650, weighing 5.5 kg, with a payload of 2 kg and a maximum reach of 650 mm with a dexterous hand.
A seven-axis arm with force feedback for $1,650 is far below the usual price of such hardware. The R1-7a weighs 5.5 kg, carries 2 kg and reaches 650 mm with a dexterous hand. Unitree is open about the compromise: the joints use low reduction ratios, which makes them fast and back-drivable but limits positional stiffness, and the maker warns that positioning errors and oscillation can occur without well-tuned control. This is an arm for learning-based control and research, not for precise assembly.
