36 Women in Science industrial robots are usually 6 degrees of freedom. The redundancy depends upon your task. For instance, if a task needs 4 degrees of freedom, and your robot has 5 degrees of freedom, then it is redundant again [ see separate section on redundancy on page 39 ]. What do you think about creating robots to look like humans? It depends on the task that you want to perform. Humanoid robots are usually used for tasks like human-robot interaction, or to take part in competitions, or to do some service. If you want to do a pick and place job, why use a humanoid robot? You can use an industrial robot with 3 degrees Or, you can rotate it about the Z axis. You can translate it about X, translate it about Y, and translate it about Z. It has 6 degrees of freedom. Now, I want to manipulate this object with my hands. This object needed 6 degrees of freedom. My hand has 7 degrees of freedom, so it has 1 degree of freedom more. My hands are redundant manipulators. So I taught you redundancy in robotics! How nice! I guess that a robot would have even more degrees of freedom. Technically, you could have infinite degrees, is that right? No, not infinite… There are some robots that have infinite degrees of freedom, but I think that I’m good at it!
