Hip Exoskeleton

Our design of quasi-direct drive actuation-based exoskeleton demonstrates mechanical versatility for being lightweight (3.2 kg overall mass), compliant (backdrivable) with high torque (36 Nm) and high control bandwidth. The electronic architecture of the exoskeleton facilitated high-level torque control, motor control, sensor signal conditioning, data communication, and power management.

Knee Exoskeleton

We developed an untethered versatile exoskeleton capable of enhancing productivity via endurance augmentation in multiple activities. This was achieved by a lightweight and compliant robot design, which minimized the energy penalty on the wearer while providing high-torque bidirectional flexion and extension assistance.

OpenArm Bimanual Robot Arms

OpenArm is a fully open-source bimanual humanoid robot arm platform developed by Enactic for physical AI research in contact-rich environments. Each arm has 7 degrees of freedom with compliant, backdrivable quasi-direct drive joints and CAN-FD communication. We use OpenArm for research on contact-rich bimanual manipulation, tactile sensing, and force-aware robot learning. For teleoperation, we use the OpenArm KER (Kinematic Equivalent Replica), a lightweight, shoulder-mounted passive arm with the same kinematic structure as OpenArm, to collect high-quality demonstration data over long sessions.

Booster K1 Humanoid Robot

The Booster K1 is a compact humanoid robot developed by Booster Robotics as an embodied AI development platform.
Specs: approximately 95 cm height, 19.5 kg weight, 22 degrees of freedom (6 per leg, 4 per arm, 2 in the head), and up to 60 Nm peak joint torque.

Knee Prosthesis

We developed a knee prosthesis using a high torque actuator (built-in 9:1 planetary gear) with a customized 4:1 low-inertia planetary gearbox. Benchtop experiments show that proposed the prosthesis can produce 200 Nm high peak torque, high compliance (2.6 Nm backdrive torque), and high control accuracy (2.7/8.1/1.7 Nm RMS tracking errors for 1.25 m/s walking, 2 m/s running, and 0.25 Hz squatting, that are 5.4%/4.1%/1.4% of desired peak torques).
