WORK EXPERIENCE:

Terrestrial Robotics Engineering and Controls Lab (TREC) Virginia Tech

(09/2015-Present)

- NSF-Funded 12 DOF Lower-Body Exoskeleton Project

Humanoid Hip Exoskeleton (pending Master's Thesis)

o The design will have three degrees of freedom for each leg (roll, yaw, and pitch), closely

mimicking the behavior of human hip movement.

o Conducted researches on the human walking cycle, the joint range of motion, and the leg

mass distribution.

o Developed the requirements for hip joints . The radial and axial loads on each joint were

calculated due to the worst case scenario, and a 3g factor of safety was used in calculations.

o 3D CAD modeled the basic frame of the hip exoskeleton with selected tapered roller

bearings on the joints.

o perfecting the design of the structure, including actuators, a motor cooling system, and

electronics.

o Utilize FEA to determine the critical sections and eliminate redundant materials.

o Conducting researches on the harness design.

o Producing prototype for testing the exoskeleton's fit and function using 3D printing

technology.

Lead Designer of Robotic Foot Humanoid Exoskeleton Project

o Calculated the toe joint speed and torque requirements based on the data from biomedical

labs.

o Used a DC motor with a planetary gearbox and timing belt to achieve 20 Nm of torque and

30 RPM of speed.

o Machined the structure in-house. A hard stop and a limit switch were used to limit the range

of motion

o Mounted force sensors on the sole to sense the load distribution on the foot and toe.

Lead Designer of a Lower-Body Exoskeleton Prototype

o Led two undergraduate students to build the lower-body exoskeleton prototype out of 80-20

Aluminum extrusion. The prototype was built to determine the proper joint locations on the

lower-body exoskeleton.

Designer of a Dynamometer

o Designed and built a dynamometer to conduct experiments on a motor cooling system. This

incorporated a test motor fighting a large braking motor. The braking motor was mounted inside

a large cross-roller bearing, and a load cell was attached via a moment arm to allow torque

measurements.

Leaf Spring Analysis for a Series Elastic Actuator

o Analyzed six cases of leaf spring using classic beam theory and NASTRAN.

o Determined the material and dimensions of each type to achieve 10mm of deflection under a 7000

N load.
