How to Build a Robot

Do you want to know how to build a robot? Creating your own robot is exciting, enjoyable and fun. However, it is important to allot enough budgets when doing this project because developing a robot is expensive. Below are the detailed steps as well as materials and tools that you need if you plan to make a functional but cost-efficient robot.

Materials and Tools

To build a robot that has similar functions with a vehicle, you will need several materials including a linear regulator, two servos, an electrolytic capacitor and a DIP socket. Aside from these, you will use an ATmega8 AVR, two ceramic capacitors, five 340 ohm resistors as well as five 1.62K ohm resistors. Other materials that are needed in this project are a PC board, five CdS photoresistors, an LED, on and off switch, a 9-volt battery, four AA battery holders, a nickel metal hydride battery, an AVR ISP2 programmer as well as a dongle programmer.

Steps

After getting all the required materials, start with designing the chassis of the robot. Draw two wheels that have diameters of six inches on a cardboard. Cut the drawings with the use of a sharp knife. Unscrew the nuts of the servos to see the inner portions of the machines. Set the controller of the servos to zero degrees. Remove the pots of the servos to stop the wheels from rotating. Look at the main gears and remove the stops. Find the slots that were connected to the pots and remove these parts. Reassemble the remaining parts of the servos.

As soon as the servos were modified, unscrew the nuts that attach the motors to the small wheels. Stick the nuts at the center of cardboard wheels and screw the servo mounts under the servos. Screw the cardboard wheels to the servos. Get two cardboards or plastic sheets that have a size of 3 x 6 inches. Attach the modified servos with the plastic sheets to finish the chassis.

Get a small bottle and cut the upper part of the bottle. Put the bottle between the servos and tie the bottle to the chassis of the robot using rubber bands. Attach the battery pack to the chassis of the robot. Seek assistance from electricians to solder remaining materials including cable wires and photoresistors to a PC board. Attach the board to the bottle that was connected to the robot’s chassis. Connect the robot to a computer and search for applications that are useful to program the functions of the robot. Use the dongle programmer and AVR ISP2 programmer when downloading applications. Check if the robot is fully functional. Download other applications to improve the robot’s functions.
