Why it’s in

The lowest-priced 7-axis arm with force control from an established robot maker that we found.
Launched in August 2026, so it is current generation.
End effectors, including dexterous hands, can be swapped at the arm tip.

What bothers us

Backordered; gripper not included.
Unitree itself warns that positional stiffness is limited by low gear ratios, so precise positioning needs tuned control.
Control programs and interfaces are to be open-sourced 'iteratively': not complete yet.
