Transparency Control of a 1-DoF Knee Exoskeleton via Human-in-the-Loop Velocity Optimisation

ICRA 2024poster

Rehabilitative robotics, particularly lower-limb exoskeletons (LLEs), have gained increasing importance in aiding patients regain ambulatory functions. One of the challenges in making these systems effective is the implementation of an assist-as-needed (AAN) control strategy that intervenes only whe…

Spherical Cubic Blends: $\mathcal{C}^{2}$-Continuous, Zero-Clamped, and Time-Optimized Interpolation of Quaternions

ICRA 2023poster

Modern collaborative robotic applications require robot motions that are predictable for human coworkers. Therefore, trajectories often need to be planned in task space rather than configuration space (\mathcal{C}\mathcal{C}-space). While the interpolation of translations in Euclidean space is strai…
