Optimal control of the E–L dynamic systems during the actuator faults
International Journal of Robust and Nonlinear Control, Volume 34, Issue 14, Page 9374-9401, 25 September 2024.Abstract In this article, we deal with finite‐time optimal control of the Euler–Lagrange (E–L) multi‐body mechanism under: uncertain its kinematics and dynamics, displacement blocking of the damaged joint caused by the actuator failure, undesirable forces/torques exerted on the end‐effector and unknown friction forces originating from joints directly ...

Trajectory Tracking Control of SCARA Robot Based on Anticipatory-type Indirect Iterative Learning [PDF]
Jisuanji gongcheng, 2017 SCARA robot is a strong coupling,multi-input and multi-output nonlinear system,which is easy to be affected by outside interference when running,and the traditional Proportional-Integra-Derivative(PID) feedback controller leads to low trajectory tracking

Position‐based fluid simulation for robotic injection sealing of pavement cracks
Journal of Field Robotics, Volume 41, Issue 5, Page 1438-1451, August 2024.Abstract Automated crack sealing could significantly benefit the maintenance of road pavements, but there is difficulty in depositing the correct volume of sealant material into the hidden crack space. A simulated model of the material flow within a crack space would allow the development of a predictive control scheme, such that the repair robot can ...

A contribution to the dynamic simulation of robot manipulator with the software RobotDyn
Vietnam Journal of Mechanics, 2004 Robots manipulators are multibody systems with tree structures. In this paper the theoretical background of the computer program RobotDyn is presented. The program is developed using Lagrange's equations and Denavit-Hartenberg matrix.

Residual Vibration Reduction of High-Speed Pick-and-Place Parallel Robot Using Input Shaping
Chinese Journal of Mechanical Engineering, 2022 Because of their elastic links and joints, high-speed parallel robots for pick-and-place operations inevitably suffer from residual vibrations that significantly degrade their positioning accuracy.

Micrometre Scale Performances of Industrial Robot Manipulators
International Journal of Advanced Robotic Systems, 2012 Robot precision is usually characterized by repeatability and accuracy. In this paper, we show that these indices are not sufficient to describe robot behaviour at the micrometre scale.

Design and development of robotic system for precise vascular access and autonomous venipuncture
Electronics Letters, Volume 60, Issue 3, February 2024.This article designs an injection needle replacement system and arm fixing unit for automatic intravenous injection without the help of a clinician. A control system is also described and validated for precise intravenous injection through experiments. Abstract The medical robot systems have the effect of reducing the work load and preventing accidents

Advances in Polymer Technology, Volume 2024, Issue 1, 2024.This work presents an investigation on the quality of parts manufactured using fused deposition modeling (FDM), which is influenced by a large number of different elements. Some of which are based on the materials used in the production of the part, though others are rather pertinent to the process parameters.
