WebMar 20, 2024 · $\begingroup$ @mcass, Ben is asking for an example because a DH table shouldn't have any asterisks. Typically an asterisk would indicate some need for a comment - your original question had an asterisk that noted lengths variable.This would not be variable in an actuated sense, but rather that the link would be manufactured in a variety … WebA i designates the D-H transformation matrix relating frame i to frame i-1. The nth link frame coincides with the end-effector's coordinate frame. Fig. 2 illustrates the spatial relative …
