and, sometimes, a hard disk to store the programmed data. digital to analog converter (DAC):a DAC converts the digital signal of the robot controller into an analog signal for driving the actuators; for example, an electric motor CD. Amplifier: since the control commands digital controller converted into analog signals by the ADC they are very weak, require amplification to really drive the electric motors of the robot manipulator. That the movement of the motors and actuators to the links of the manipulator is transmitted. When preference should be given to a pulley belt rather than the gears? When the load is much higher Figure 2.2 Example of a robot pulley Know why What are the advantages of using mechanisms and no other arrangements transmission? The advantage is to reduce the weight and flexibility of elements excess belt drive, chain gears What are the different ways to classify a robot? transmissions are used in a robot manipulator. For its Application:many robots are designed for assembly work and are not easily adaptable for other
