Parts of a Robot
February 17th, 2008 by dmrobots
A. Write down the 5 main parts of a robot and give an explanation on each, including what specific function does the part perform, what does this allow the robot to do?
CONTROLLER :
A working robot which is not connected to the computer is yet still to be found. The controller is the computer or “think tank” which the robot is receiving the instructions from. The controller also has the ability to connect to a network to work together with other machines , usually a set of instructions is programmed into the controller. Most people these days program robots themselves, I have yet still to see when a robot programs another robot to function the same as it is itself. Since the robot is programmed, it can only do what it is programmed nothing else, but in the near future we may be getting a self-reliant and independent robot that can think on their own or even program themselves but for now, we tell it what needs to be done.
ARM :
Many, but not all, robot arms resemble a human arm with all the necessities a human arm has such as the shoulders, elbows, wrists and even the fingers on most advanced robots. The arm of a robot is very important it is the part that positions the end-affector and sensors to do their pre-programmed business. With the robot arms identical to a humans one the robot has freedom in to position itself in many ways to suit its environment, with every joint in a robot arm it is free to move as much as the joints let it. For example a robot with 3 joints it can only move up and down, forward and backward and left and right.
DRIVE :
A robots drive is like its engine that gives it its power, without it the robot would just sit there and do no help. The drive is needed to drive the links (the sections between the joints into their desired position). Drives can be powered b air, electricity or water pressure.
END- EFFECTOR:
The gripper, tweezers, vacuum pump, blowtorch, clamps or human hand attached to the robots arm is called an “end-effector”, it is changed or built to suit the purpose of the robots. For example a robot that needs to cut grass will not have an end-effector which is a flamethrower, you would need a chainsaw. Some robots even have the ability to change their end-affectors to suit the task at hand but reprogramming will be needed, unless this robot is advanced, self- efficient and not to mention expensive.
SENSOR :
Robots these day and time are equipped with a sensor to enhance its ability to do the job right and efficiently. A robot to match a human’s sensors are yet to match, robot’s senses and abilities are very limited. Sensors send information back to the controller using electronic signals. Having sensors lets the robot “think tank” to familiarize itself to its current surroundings and the position of its arms.
B. Write down the 6 degrees of freedom.
1.Horizontal
2.Vertical
3.Depth
4.Pitch
5.Yaw
6.Roll
