Robot learning Note(1) – Basic

As we all known that robotic and automation industries will become more and more popular in the future, and I’m working at robotic industry. So from now on, I’ll write a series of my learning notes about robot and I’m eager to discuss with my friends.

A famous paragraph refer to the first chapter of “Sprinner handbook of robotics”

Robots often consist of a large number of
degrees of freedom so that they can provide the rich
set of three-dimensional (3-D) motions that may be re-
quired for a range of tasks. The kinematic and dynamic
relationships between the joint actuators’ motion and
torques, and the desired motion and force for a task can
be very complex. The design of the link and joint struc-
tures, as well as the actuation, to achieve the desired
performance is also challenging.
