About

Yuanhao Bao is a robotics researcher focused on advancing the design and performance of lightweight, high-output manipulators and 3D-printed robotic structures. His work centers on two key areas: enhancing the mechanical capabilities of robot hands and wrists, and optimizing the structural dynamics of additively manufactured robot arms. Bao’s major contribution includes the development of a manipulator equipped with a differential wrist mechanism that combines the torque of two motors, significantly increasing both fingertip force and wrist torque while keeping the hand’s weight at just 450 grams—comparable to a human hand. This design, published in 2022, has garnered 5 citations for its practical approach to improving dexterity and power in robotic manipulation. Additionally, Bao has pioneered the study of how 3D printing filling density affects the vibration characteristics of robot structures. His 2024 paper (4 citations) and 2025 follow-up (2 citations) establish equations to estimate natural frequency and damping ratio, enabling researchers to select optimal filling densities for lighter, more cost-effective robot arms without compromising structural integrity. Bao’s work is notable for bridging materials science and mechanical design, offering tangible guidelines for the next generation of agile, energy-efficient robots.
