The types of Tomii robotic arm are: according to the different forms of structure is divided into multi-joint robotic arm, right-angle coordinate system robotic arm, spherical coordinate system robotic arm, polar coordinate robotic arm, column coordinate robotic arm and so on. The figure on the right shows a common six degrees of freedom robot arm. He has X movement, Y movement, Z movement, X rotation, Y rotation, Z rotation composed of six degrees of freedom.
The horizontal multi-joint robot arm generally has three main degrees of freedom, Z1 rotation, Z2 rotation, Z movement. By adding X rotation, Y rotation to the actuating terminal can reach any coordinate point in space.
A right-angled coordinate system robot arm has three main degrees of freedom, X movement, Y movement, and Z movement, and can reach any coordinate point in space by adding X rotation, Y rotation, and Z rotation to the actuator terminal.
