Our paper “Variable Stiffness Springs for Energy Storage Applications” is published in IEEE ICRA 2020
Aug. 31, 2020—Authors: Sung Y. (Joel) Kim, Tiange Zhang, and David J. Braun Abstract: Theory suggests an inverse relation between the stiffness and the energy storage capacity for linear helical springs: reducing the active length of the spring by 50% increases its stiffness by 100%, but reduces its energy storage capacity by 50%. State-of-the-art variable stiffness actuators used...
New NSF (CMMI/DCSD) Award: What if robots could teach robots the same way parents teach their children?
Aug. 18, 2020—This project introduces learner-helper robot pairs to enable the learner robot to use physical experimentation to improve its performance on repetitive task, without accurate analytical or numerical models.
