Lifetime Prediction of Permanent Magnet Synchronous Motor in Selective Compliance Assembly Robot Arm Considering Insulation Thermal Aging [PDF]
The direct-drive selective compliance assembly robot arm (SCARA) is widely used in high-end manufacturing fields, as it omits the mechanical transmission structures and has the advantages of high positioning accuracy and fast movement speed. However, due

Vibration and Kinematic Analysis of Scara Robot Structure
This paper presents a procedure for assessing the vibration analysis of type SCARA robots. The motion and running conditions of such robots are very complicated that leads to produce vibration and shock which are generated by arm profile in running ...

Motion System Optimisation for Direct‐Drive Selective Compliance Assembly Robot Arm
This article presents a new optimisation framework based on the characteristic parameters surrogate model to solve the computation burden of the direct‐drive selective compliance assembly robot arm motion system optimisation. In addition, the optimised prototype has 33% and 12.5% improvements in reliability and unit production per hour, respectively ...

Discrete time robust control of robot manipulators in the task space using adaptive fuzzy estimator [PDF]
This paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. A novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty ...

In order to investigate the characteristic properties and their dependence on compression rates, a soft elastomeric liquid metal‐embedded pressure sensor has been fabricated using the mechanical micromachining process. Abstract Soft sensors are flexible and stretchable, and because of this, they can be used on a wide range of surfaces, regardless of ...

Trajectory Tracking Control of SCARA Robot Based on Anticipatory-type Indirect Iterative Learning [PDF]
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

Optimal control of the E–L dynamic systems during the actuator faults
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 ...

A contribution to the dynamic simulation of robot manipulator with the software RobotDyn
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.

Position‐based fluid simulation for robotic injection sealing of pavement cracks
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 ...
