Simulation of muscle-powered jumping with hardware-in-the-loop ground interaction (2018)
Journal Article
Eberhard, E. A., & Richards, C. T. (2018). Simulation of muscle-powered jumping with hardware-in-the-loop ground interaction. https://doi.org/10.1109/AIM.2018.8452298

We developed a novel reverse haptic interface to augment forward dynamic simulations with real-world contact forces. In contrast with traditional haptics, in which a realworld user drives an interaction with a simulated environment, reverse haptics a...

The dynamic role of the ilio-sacral joint in jumping frogs (2018)
Journal Article
Richards, C. T., Eberhard, E. A., & Collings, A. J. (2018). The dynamic role of the ilio-sacral joint in jumping frogs. Biology Letters, 14(9), https://doi.org/10.1098/rsbl.2018.0367

A striking feature among jumping frogs is a sharp pelvic bend about the ilio-sacral (IS) joint, unique to anurans. Although this sagittal plane hinge has been interpreted as crucial for the evolution of jumping, its mechanical contribution has not be...

A novel kinematics analysis method using quaternion interpolation – a case study in frog jumping (2018)
Journal Article
Richards, C. T., & Porro, L. B. (2018). A novel kinematics analysis method using quaternion interpolation – a case study in frog jumping. Journal of Theoretical Biology, 454, 410-424. https://doi.org/10.1016/j.jtbi.2018.06.010

Spherical Linear Interpolation (SLERP) has long been used in computer animation to interpolate movements between two 3D orientations. We developed a forward kinematics (FK) approach using quaternions and SLERP to predict how frogs modulate jump kinem...
