The SCARA robot is a multi-joint robotic system whose structure usually consists of two rotational joints and one translational joint. Therefore, the number of motors inside a SCARA robot depends mainly on the number of its joints. Specifically, the number of motors inside the SCARA robot can be divided into the following aspects:
Rotary joint motor:The two rotating joints of the SCARA robot are usually driven by a motor to enable the rotational movement of the robot in the horizontal plane. Each rotating joint requires a motor, so in this regard, SCARA robots usually have at least two rotating joint motors.
Translational Joint Motor:The translational joints of the SCARA robot are responsible for movement in the vertical direction and usually require a motor to control it as well. This makes the number of translational joint motors one.
In summary, a typical SCARA robot usually contains at least two rotary joint motors and one translational joint motor inside. The three motors work together to enable the robot to perform complex tasks such as assembly, handling, and precision positioning. It is important to note that the specific design and manufacturing may vary depending on the manufacturer and model, but the number of motors mentioned above is a common configuration.
