Shoulder singularity
Splet$\begingroup$ I have struggled to describe this other singularity. It is easier to show the wrist singularity because of the actual physical alignment of the axes of q4 and q6. But when the arm is elbow-down, with the wrist center in the plane of q1 and q2 (it would be on the q1 axes except for the elbow offset), then q1 only rotates the wrist center in place - … Splet01. maj 2024 · In this article, I’m focusing on the last example. We will use a typical shoulder feature as shown in Fig. 1. This represents a transition between widths of a component. It is assumed that the FEA model ignores the fillet radius and represents this as a right angle. ... We have stumbled into a stress singularity. Classical elasticity theory ...

In this paper we present a shoulder design using a novel …
Splet10. okt. 2024 · The singular configuration of the arm is called wrist/shoulder singularity , while that for the leg, hip singularity. Figure 2c shows another type of singular configuration for the right arm. The singularity is due to the alignment of the two axes in the shoulder joint and the elbow joint being at 90 ∘. The end-link loses a translational ... SpletThe singularity-consistent path-planning and motion control approach has so far been successfully tested within a teleoperation environment, but with separate control of the positioning subsystem and the wrist of the slave arm. In this paper, we show that the approach can be applied to a 6-DOF slave arm with a non-spherical wrist. The problems …
