Output devices are devices which shows us what the computer is processing. Without an output device the computer would do lots of processing but we can't see the results. So yes a robotic arm is an output device.
Input
Yes, the robotic arm on the space shuttle is considered a robot because it is a mechanical device that can be programmed to manipulate objects in its environment autonomously.
Robotic arms are often called prosthetic arms if they are on a person. If it is a robotic arm on a machine, then it is called a robotic arm.

The number of motors in a robotic device is dependent upon the functionality of the robotic device. A simple robotic arm that acts as a sorting device on a conveyor may only need a pneumatic piston and as such would require no "motor". As a robotic device becomes more complex, the requirements for other actuators will increase. To design a robot will take some time and thought. Only the designer can decide how many motors will be required.
First, you must be capable of distinguishing the real world from the world of fantasy and make-believe. The robots that you see at the movies are not real. They don't exist except in the world of make-believe. Second, if you want to build a robot, decide what you want it to do. If you wan a robotic arm that opens a door whenever something approaches, determine the type of sensor you want to use, run the output to the appropriate relay, SCR or other switching device, connect that output to a hydraulic, pneumatic or electromagnetic actuator, then connect the actuator to the arm, making certain that the arm is attached appropriately. Once you have that completed, you have a robotic door opener. When the sensor detects the presence of an object, it sends a signal to the relay, SCR or other switching device, the output activates the actuator, the actuator moves the arm and the arm opens the door. It's magic... or robotics.
What is an output arm?
Output.
No; It's her armour
no its storage
A laser printer is an output device.
That is not a simple question to answer. A robotic device can be controlled by many different types of computers, anything from a small imbedded processor to a large mainframe computer. Knowing how to program the robotic device requires that you know how to cause the computer to set the appropriate output that is connected to the individual circuits of the robot. Many computers can be programmed using what is referred to as a "higher level language", and some robotic devices even have programs running that allow you to make simple robotic commands to cause the computer to set the appropriate outputs. There is no simple way to tell you how to program a robotic device, since they are all different.
