For some time now, robotics has ceased to be a symbol of a fantastic future and has become a very real application to modern technological advances. For a lot of money, you can buy a multifunctional robot for any purpose - from toys and interior decorations to home cleaning products.
Instructions
Step 1
To make a robot, you will need an old ball mouse, two electric motors, a switch, a transistor, an LED, 1K and 10K resistors, an electrolytic capacitor, an audio cassette, a floppy disk, a 9V Krona battery and a battery holder, as well as DPDT 5V and LM386 parts.
Step 2
Disassemble the mouse. Pull the microcircuit out of the case and remove several parts from it - the black plastic one located to the right of the cable exit, and the transparent white one with two metal connectors located at the plastic gear - in duplicate.
Step 3
You only need these two parts - the rest of the microcircuit can be thrown away. Remove all elements and parts from the mouse completely to leave an empty plastic case.
Step 4
Remove the small tape reels from the cassette tape - they will act as casters. Put the wheels on the motor axle and make tires - wrap each wheel with a narrow strip of rubber covered with rubber glue.
Step 5
On top of the first two or three turns, glue one turn of rubber of a different color.
Step 6
Solder the wires to the DPDT 5V part - blue to the yellow contact, and the orange to the orange contact. Connect 2N3904 to this part. Solder together an electrolytic capacitor, a 10K resistor, and the plastic black switch you removed from the mouse chip.
Step 7
For part LM386, bend the outermost pair of metal strips towards each other. Assemble the circuitry inside the mouse body in the correct order. Cut holes in the side walls of the bottom of the mouse case and glue the electric motors into it. On the outside of each electric motor, a wheel with a rubber tire must be put on the axle.
Step 8
In the upper half of the mouse body, drill three holes where the buttons used to be. Drill one hole in the back of the case.
Step 9
Solder the two transparent sensors that you took out of the microcircuit at the beginning of work to the wires. Install the LED in the middle hole of the front of the case and solder a 1K resistor to it. Connect to the LED two sensors soldered to the wires, and insert the switch into the back hole of the mouse.
Step 10
Connect the top of the mouse to the bottom by connecting the sensors and LED, and then connecting the battery and switch. Solder both parts of the mouse body, glue a piece of plastic from a floppy disk to the front, depicting a bumper, and try to turn on and start your robot.
