A02

A02 extends Feagine's tendon-driven architecture to two flexible segments and four degrees of freedom. The 1.5 kg desktop system provides a 30 cm arm length and carries up to 400 g, giving laboratories a larger compliant workspace than A01 while remaining compact enough for benchtop experimentation. Published maximum end-effector speed is 0.78 m/s.

Researchers can operate A02 through Feagine's graphical interface or program it through ROS 1, ROS 2, Python and C++. The control stack exposes joint-space, Cartesian and low-level tendon commands, while MuJoCo and SAPIEN environments support simulation and algorithm development before transfer to hardware.
