The article will discuss how to make a miniature vibro-robot do it yourself. Such robots when turned on, they begin to dance on a smooth surface, winding circles on the table. This is because an unbalanced weight is installed on the engine, which creates vibrations. Everyone can assemble such a robot at home, this requires a minimum of skills and materials.
Specifically this model The robot was called Itty Bitty. The vibro-motor from an old mobile phone is used here as a “heart”, and the robot is powered by a 3V clock battery.
Materials and tools for creating a robot:
- 3V flat battery;
- vibration motor from an old mobile;
- one large paper clip;
- soldering iron with solder and flux;
- electrical tape;
- hot glue;
- marker of dark color.
Of the tools you need a file, alcohol and pliers.
The manufacturing process of the robot:
Step one. Create the legs of the robot
Creating the legs of the robot is the most crucial moment in this whole thing. The operation of the entire robot will depend on how correctly they are made. First of all, the legs should be strong, since with vibration the robot will jump quite strongly. They are made from a single piece of wire. A paper clip is best suited for these purposes. First of all, it must be straightened and then divided into 6 equal parts. As a result, the length of each individual part will be 1/16 inch.
An important point when working with a paper clip is the smoothness of movement. If you bend the clip too quickly, it may break. If angles extend beyond 90 degrees, they must be rounded.
Now you need to take one mark and bend the clip 90 degrees in this place, at the other mark you need to bend in the opposite direction. If the end of the clip is rounded during bending, this greatly reduces the likelihood of a fracture.
On the third mark you need to make a 90 degree bend, but the place of the bend should be as far as possible from the end.
At the fourth mark, a bend of 180 degrees is made, the end should be behind.
An inflection of 90 degrees is made on the fifth leg, and it should be as far away as possible from the other two adjacent legs. In conclusion, the legs need to be adjusted so that everyone does not evenly touch the floor.
Step Two Engine installation
The battery acts as a supporting element in such a robot. You need to take tremokle and stick a vibro-motor to it. After that, one of the motor wires needs to be soldered to the battery contact, this will be the top contact. In order to lay down the solder, the battery needs to be slightly scratched, this can be done with a file.
Step Three Glue the legs
Now all that remains is to stick the legs to the robot. To do this, you need to put the battery on the table, and on top of it put the legs of the robot. Next, the legs need to be pressed down; for this, a linear level or piece of aluminum can be applied to the legs. Before applying glue, it is advisable to degrease the surface of the battery with alcohol. There is no need to regret the glue, since when working on the legs, a sufficiently large force acts. If you stick the feet badly, the robot may fall apart during operation.
No need to rush to run the robot, the glue must be solidified. The author recommends putting the workpiece in the refrigerator, so the glue dries faster.
That's all, the robot is ready and you can check it. To turn on the robot, you need to take a piece of electrical tape and stick the second wire from the motor to the battery terminal. By placing the robot on a smooth table, you can now observe what it will do.
