Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

Advanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Muscle Control of an Extra Robotic Digit

Advanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

Series Compensated Low Frequency Transformers Emulating Multipulse Rectifiers for Harmonic Current Content Minimization in Electrical Grids

IEEE Access
This paper explores the use of series compensated low frequency transformers (SCLFT), operating in parallel to traditional low frequency transformers (LFT), to attenuate harmonic distortion caused by nonlinear loads in electrical networks. The proposed strategy achieves harmonic cancellation through a controlled phase shift between the SCLFT and LFT ...
