A Stability Training Method of Legged Robots Based on Training Platforms and Reinforcement Learning with Its Simulation and Experiment

open access: yesMicromachines, 2022
This paper continues the proposed idea of stability training for legged robots with any number of legs and any size on a motion platform and introduces the concept of a learning-based controller, the global self-stabilizer, to obtain a self-stabilization

ON THE CONTROL OF THE MOTION OF A BOAT [PDF]

open access: yesMathematical Models and Methods in Applied Sciences, 2013
In this paper we study the control of the motion of a boat, viewed as a rigid body S with one axis of symmetry, which is surrounded by an inviscid incompressible fluid filling ℝ2\S. We take as control input the flow of the fluid through a part of the boundary of the boat.

Controllable motion textures [PDF]

open access: yesACM SIGGRAPH 2008 posters, 2008
While producing an animation, we often rely on the artist to make it manually, or sometimes we generate the animation by some physical simulations. However, the animation we created by these methods always has fixed length and is very difficult to reuse. For 3D animation production, in practice, we always need some animations with variable lengths, for

The Long-Term Maintenance of Upper Limb Motor Improvements Following Transcranial Direct Current Stimulation Combined with Rehabilitation in People with Stroke: A Systematic Review of Randomized Sham-Controlled Trials

open access: yesSensors, 2021
Background: The effectiveness of transcranial direct current stimulation (tDCS) in the upper limb (UL) motor rehabilitation of stroke has been widely studied. However, the long-term maintenance of its improvements has not yet been proven.

The motion control problem for the CyberCarpet [PDF]

open access: yesProceedings 2006 IEEE International Conference on Robotics and Automation, 2006. ICRA 2006., 2006
Exploration of virtual worlds with unconstrained locomotion possibilities for the user is the main objective of the European research project CyberWalk. This should be achieved through the use of an actuated platform (the CyberCarpet) that compensates for the walker's locomotion in such a way to keep her/him close to the platform center.

Design of an Artificial Neural Network Algorithm for a Low-Cost Insole Sensor to Estimate the Ground Reaction Force (GRF) and Calibrate the Center of Pressure (CoP)

open access: yesSensors, 2018
As an alternative to high-cost shoe insole pressure sensors that measure the insole pressure distribution and calculate the center of pressure (CoP), researchers developed a foot sensor with FSR sensors on the bottom of the insole.

Research on a Wide-Output Resonant Converter with Multi-Mode Switching

open access: yesEnergies, 2022
In this article, a resonant converter based on a series-parallel self-adjusting rectifier structure is proposed. By changing the driving signal of the switch, the converter has four working modes: full-bridge structure frequency modulation control, full ...
