Singularity avoidance for SCARA robots

Robotics and Autonomous Systems, 1992
Abstract This paper addresses the following optimization problem: for a SCARA robot and a task to be performed at a number of discrete points on a workpiece, find the workpiece position for which the robot will perform the task while remaining as far away as possible from singular configurations.

Camera assisted calibration of SCARA arms

IEEE Robotics & Automation Magazine, 1996
Robot calibration is an effective and economical means for enhancing the accuracy performance of a robot manipulator through modification of its control software. This paper reports some research results by applying Lenz and Tsai's approach (1989) to calibrate a SCARA arm equipped with a hand-mounted camera.

On the dynamics of SCARA robot

Robotics and Autonomous Systems, 1992
Abstract Assembly automation using robots has proven to be very successful. It has been shown that use of robots improves the accuracy of assembly, and saves assembly time and cost as well. SCARA (Selective Compliance Assembly Robot Arm) type robots have been widely used in industry for assembly operations in both the mechanical and electronics ...

OPTIMIZED DYNAMIC CALIBRATION OF A SCARA ROBOT

IFAC Proceedings Volumes, 2002
Abstract This paper presents experimental results for the dynamic calibration of the SCARA robot. In particular, optimized techniques are applied to determine optimal excitation trajectories for the identification experiment, and the resulting performances are compared with those obtained using standard robot “working” trajectories.

Collision avoidance for two SCARA robots

Proceedings. 1991 IEEE International Conference on Robotics and Automation, 2002
A method for planning collision-free trajectories of two SCARA robots in a common workspace is described. The robots are treated as a single redundant system. A collision map representing the intersection of the robots is developed in a two-parameter space.

Design of SCARA robot

1994
In the first part the paper presents the analysis of a SCARA manipulator working area. The second part concerns with the dynamic analysis on the basis of Lagrange equation. The moments in the particular link and the actual torque courses related to the real time and real robot form was calculated.

A Method of Gravity Offloading with a SCARA Manipulator

2011 21st International Conference on Systems Engineering, 2011
This paper presents a mechanism and control law which is currently under development that is intended to provide gravitational compensation so that lunar bound systems can be terrestrially tested in a simulated lunar gravitational field. The mechanism is a selective compliant articulated robotic arm (SCARA) manipulator.

Reconfigurable Design and Structure Optimization of SCARA

2019
Selective compliance assembly robot arm (SCARA) has several unique characteristics with high speed, accuracy and stability in horizontal motion and so on. In order to make SCARA to have variable working radius, the big arm was designed into modular combination in this paper.
