Huai-Ti Lin

Ph.D, Biology, 2010

Biographical sketch
Huai-Ti Lin successfully defended his Ph.D thesis in January 2011at Tufts Department of Biology. His doctoral research focused on the biomechanics and behavioral adaptation in soft-bodied animal locomotion. Specifically, he devised a system to measure the ground reaction forces from a crawling caterpillar and revealed, for the first time, that soft-bodied animals use the substrate as their external skeleton for force transmission. As part of his research in neuromechanics of soft-bodied locomotion, Huai-Ti also studied non-linear behaviors of soft materials and worked in the Mechanics of Soft Materials Laboratory. To investigate how to embed adaptive behaviors as part of the soft material mechanics, he was also involved with the development of soft robots at Tufts Biomimetic Devices Laboratory in collaboration with Tufts Department of Mechanical Engineering and Biomedical Engineering. Beside many soft crawling-inching robots he created, Huai-Ti also implemented a ballistic rolling robot to mimics an escape behavior in caterpillars. This dynamic morphing behavior allows over 0.5m/s speed for this caterpillar soft robot, making yet another record for soft robots of this class.
Huai-Ti has moved on to animal flight research and UAV robotics for his post-doctoral training. Flight has always been his passion. However, his interest in soft-bodied animal locomotion and soft robotics technology still remain. Someday he might come back to them as opportunities present themselves. For now, he will take flight.
