How to Design a Robot

Robots have long captured our imagination. They have taken on many forms over the years. However, working robots are normally designed not as a multitasking device that resembles a human being, but a device that is created to perform one or two specific tasks with a high degree of efficiency. If you are handy with electronics and want to try your hand at designing your own robot to handle some simple task, here are some ideas on how to do just that
Instructions

Basic Knowledge of Electronics
Step1:
Define the function or functions that the robot will perform. Knowing what the device is to accomplish is the first step in determining what elements must go into the design. For example, a robot that is expected to pick up objects will need to be designed with an arm mechanism. A robot that is expected to sweep or vacuum will require some type of wheels or locomotion mechanism to move across the floor.
Step 2:
Create a rough sketch of the robot’s exterior. The design does not have to be perfect at this point. A rough sketch will serve as the basis for the general look of the device that you can refine as you move deeper into the project.
Step 3;
Determine the internal components that will necessary to make the robot operational. This may include circuit boards, wiring, and various other components. Compile a list on a notepad of the necessary components and how they would relate to one another. Knowing what you need for the internal workings will make it easier to determine how big the body of the robot will have to be in order to include all necessary elements.
Step 4:
Address the layout of the interior components for the robot. The placement of components may be influenced by some of the exterior features. If the robot is equipped with red flashing eyes, then the circuitry and sockets for the small bulbs will need to be placed in line with the location of the eyes on the exterior of the device. Determining the placement of interior components can usually be done by creating cross section drawings of the components within an exposed area of the outer shell of the shell.
Step 5:
Enhance the exterior of the robot. Once the interior components are placed, you can begin to determine the color scheme and any esthetic elements that will work along with the functionality of the final design.
Step 6:
Develop the working blueprint for the robot. Using the sketches and the list of components, begin to create the blueprints for the creation of the shell, all exterior features such as arms or sensor lights, and also the exact layout and connectivity between the internal components. The blueprints will provide the basis for the purchase of necessary materials to build the robot based on your design
