Solving the Singularity Problem of Non-Redundant Manipulators by Constaint Optimization [PDF]
, 1999 A solution to the singularity problem of a non-redundant robot is proposed by reformulating the inverse kinematic problem as a constraint optimization problem.

Clarke Transform: A Lingua Franca for Continuum Robotics
Advanced Intelligent Systems, EarlyView.Using the Clarke transform, both robot‐dependent mappings are known exactly for kinematic models, leading to a complete chain of transformations between spaces with associated abstraction. This eases the derivation. Therefore, proposing the Clarke transform as a lingua franca and utilizing a practical fact sheet can pave the way for more systematic ...

Shape Sensing, Mapping, and Obstacle Avoidance of the Continuum Manipulator in Confined Environments
Advanced Intelligent Systems, EarlyView.An integrated sensing framework combines capacitive sensors, IMU, and laser array sensor. The shape reconstruction is finished by backpropagation neural network. Accurate shape estimation (relative error of 1.04%) is maintained under a 110 g tip load, while a miniaturized VL6180X array enables local environmental reconstruction and reactive obstacle ...

Kinematic‐Aware Diffusion Model Correction for Human Motion Generation via Pose Transfer
Advanced Intelligent Systems, EarlyView.Overall architecture of the proposed video kinematic pose correction pipeline. The framework integrates diffusion‐based video generation, multi‐estimator skeleton extraction, temporal Kalman smoothing, biomechanical constraint enforcement, and pose‐conditioned frame regeneration via Pose‐guided Image Synthesis and Editing. This paper presents Kinematic‐

General-Weighted Least-Norm Control for Redundant Manipulators under Time-Dependent Constraint
International Journal of Advanced Robotic Systems, 2015 Previous research dealing with constrained kinematic redundancy problems focuses on manipulators with time-independent constraints. This paper extends the general-weighted least-norm (GWLN) method to manipulators with time-dependent constraints by ...

An Active Knee–Ankle–Foot Orthosis With Torque‐Dense, Low‐Impedance Knee Actuation
Advanced Intelligent Systems, EarlyView.This article presents the simulation, design, and clinical validation of a robotic active KAFO with torque‐sensitive actuation. By passively and continuously adapting the transmission ratio in response to the knee torque, the torque‐sensitive actuator overcomes the tradeoff between torque, weight, and impedance observed in conventional robot actuators,

Environmentally Symbiotic Plant Robot
Advanced Intelligent Systems, EarlyView.An environmentally symbiotic plant robot is presented that externalizes its drive system to plants and soil. By converting germination and growth forces into locomotion, the robot sustains a closed cycle of seeding, germination, growth, and reseeding, autonomously traveling on soil for 30 days using only environmental resources while distributing seeds

Redundancy Pay and Collective Dismissals [PDF]
Redundancy payments for collective dismissals are incorporated into a Shapiro-Stiglitz model of efficiency wages. It is shown that a fixed payment will lower wages, leave employment and welfare unaffected if there are no wage-dependent taxes, no ...
