The performances of an ideal wrist would be constant and independent of its configuration.
If the elbow is already flexed, the hand is guided around the elbow to grasp the fetus' forearm and wrist.
Figure 5 shows the estimated and measured shoulder, elbow and wrist joints angles for four different movement velocities.
In the upper extremities, wrist and finger extensors and deltoids were the most affected muscles.
Is effeminacy a limp wrist, a set of facial mannerisms, a way of crossing one's legs, a certain posture?
This analysis shows that the new parallel wrist can reach singular configurations (translation singularities) in which the spherical constraint between end effector and frame fails.
Subsequent to this, attention should be devoted to maximizing the range of wrist movements.
There is a hollow wrist mechanism at the end of the arm where pneumatic and electrical services to end of arm tooling can be routed.
