There are various ways to build a robot, ranging from complex and time-consuming to easy and simple. For example, you can build a budding robot that moves using a toy motor, a 9V battery, a metal coin, and a small plastic case. While this type of robot can't do impressive things, you can follow the steps below to learn the basics of robotics.
Step
Step 1. Prepare the items listed below
Step 2. Make a hole in the Tupperware box using a knife
This hole will serve as a motor mount.
Step 3. Buy a motorbike like the one in the picture from the toy store
The motor purchased must have visible metal parts that can be welded together. Ask for the type of motor that can be welded and modified when shopping at a toy store.
Step 4. Connect one cable on the right side of the motor
Make sure the metal end of the cable is connected to the metal on the motor.
Step 5. Connect the other end of the cable on the left side of the battery
Make sure again that the metal on the end of the cable is attached to the motor.
Step 6. Glue the coins you prepared on the motor shaft using hot glue
Step 7. Weld the end of the positive (red) wire connected to the motor on the non-momentary type switch
The switch in the picture is a SPST (Single Pole Single Throw) type switch. This type of switch does not need to be continuously pressed so that electricity can continue to flow. You only need to press the button once and the electricity will continue to flow until you turn it off.
Don't forget to make sure the metal end of the cable is connected to the metal conductor on the switch
Step 8. Use glue to attach the motor to the previously made mounting holes
Also paste whatever you want to stick to the robot.
Step 9. Use a new cable to connect the battery to your robot
Weld the end of the red wire on the positive pole of the battery and the negative (black) wire on the negative pole of the battery.
Step 10. Connect the positive (red) end of the battery connected to the pin located in the center of the switch
Make sure the metal tip is in contact with the metal conductor located in the center of the switch before welding.
This step is necessary for electricity to flow through the switch before it can be used by the motor
Step 11. Connect the negative (black) end of the cable connected to the battery with the negative end of the cable that is connected to the motor
With this, the battery will start supplying electricity to the circuit you created.
- Connect the positive and negative leads connected to the battery compartment and the motor if you are not using the LED light.
- The LED light will be damaged if it is connected directly to the battery. If you want to add an LED light, use a 350ohm resistor on the positive end of the lamp and connect the positive end of the lamp to the positive end of the battery.
Step 12. Use hot glue to attach the Tupperware lid to the small cardboard box
Step 13. Place the Tupperware on top of the lid that has been attached to the cardboard box
You can hide the battery in a cardboard box and your robot is ready to go!
