Motion Control of Cable-Driven Continuum Catheter Robot Through Contacts

open access: yesIEEE Robotics and Automation Letters, 2019
Catheter-based intervention plays an important role in minimally invasive surgery. For the closed-loop control of catheter robot through contacts, the loss of contact sensing along the entire catheter might result in task failure.

A novel approach of Consensus-based Finite-time Distributed Sliding Mode Control for Stewart platform manipulators motion tracking

open access: yesResults in Engineering
The Gough-Stewart Platform, often referred to simply as the Stewart Platform, is a parallel mechanical system with six degrees of freedom, which is widely employed in simulation and precise applications. This study gives a thorough Lagrangian-based model

Dynamic friction modelling without drift and its application in the simulation of a valve controlled hydraulic cylinder system

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2014
The frictional modelling literature is reviewed, and it is demonstrated that unrealistic drift results when the shape coefficient is 1.0 for the LuGre and the integral friction models.

Research on robot motion control and trajectory tracking based on agricultural seeding

open access: yesКомпьютерная оптика, 2023
With the development of science and technology, agricultural production has been gradually industrialized, and the use of robots instead of humans for seeding is one of the agricultural industrializations. This paper studied the seeding path planning and

Biography of David F. Cavers [PDF]

open access: yes, 1977
A method for backstepping control of rigid body motion is proposed. The control variables are torques and the force along the axis of motion. The proposed control law and lyapunov function guarantee asymptotic stability from all initial values except one

Relative motion at the bone-prosthesis interface [PDF]

open access: yes, 1994
Bone ingrowth in porous surfaces of human joint implants is a desired condition for long-term fixation in patients who are physically active (such as in sport or work). It is generally recognized that little actual bone ingrowth occurs. The best clinical
