Advanced Robotics Research, EarlyView.A sea turtle‐inspired amphibious robot uses simulation‐guided optimization to adapt its flipper coordination to different environments. Sensitivity analysis and multiobjective Bayesian optimization identify terrain‐dependent controllers that are validated on hardware.

Distributed Micropneumatic Sensors for Soft Robots to Detect Touch and Pose
Advanced Robotics Research, EarlyView.Soft robots need integrated touch and pose sensing for safe and reliable operation. This work presents a three‐fingered soft gripper with 18 micropneumatic sensors made from the same materials as its pneumatic actuators. By measuring airflow resistance changes in deforming microchannels of the sensors, finger pose and contact are detected, enabling ...

XeraBorg: Neural Control of Tail‐Flick Escape for Backward Propulsion in Cyborg Crayfish
Advanced Robotics Research, EarlyView.This work presents the first controlled tail‐flick propulsion method for the cyborg Cherax quadricarinatus. Comprehensive experiments establish a foundational framework for using the crayfish's natural escape mechanism as a locomotion strategy, expanding its potential as an underwater and amphibious mobile robot.

A new space-vector-based sigma delta modulation scheme for any general N-level voltage source inverter is proposed in this paper, which directly quantizes the reference space vector. The proposed scheme uses the sigma delta modulation with the quantizer implemented by the proposed space vector quantizer. A new scheme is proposed for directly quantizing

CORDIC Implementation of Space Vector Modulation
2008 IEEE Industry Applications Society Annual Meeting, 2008Space vector modulation (SVM) is commonly used in motor drives. In order to reduce the calculation time in SVM a coordinate rotation digital computer (CORDIC) algorithm is used to generate trigonometric functions. The algorithm is implemented using a microcontroller.

Modules are a generalization of the vector spaces of linear algebra in which the “scalars” are allowed to be from an arbitrary ring, rather than a field. This rather modest weakening of the axioms is quite far reaching, including, for example, the theory of rings and ideals and the theory of abelian groups as special cases.

The theory of vector spaces—also referred to as linear algebra—is as important and widespread in higher mathematics as calculus. Most notably, it provides a complete understanding of the solvability of systems of linear equations. For our purposes, we will need no more than the basic features of the theory.
