This homemade product will be interesting to everyone who likes to craft something unusual with their own hands. Despite the fact that this mechanism is absolutely useless at home, this cockroach will replenish the collection of funny home-made toys.
However, there are still some benefits from homemade work. To make such a design is not so simple, so working on this project is a great gymnastics for the mind and training for the hands. Also, a mechanical bug will help arouse interest in technical creativity in children, which is much more fun than watching cartoons or playing games on a tablet.
Features of the manufacture of a mechanical cockroach
The most common scheme for constructing a mechanical cockroach is based on simple kinematics - extremely pairs of legs move on a horizontal plane, and the middle pair of legs moves on a vertical plane. However, the gait of such a cockroach is "lame."
Therefore, it is better to take another, more thoughtful scheme as the basis, where the extreme legs move on the horizontal plane, and the middle legs in two planes. When moving, such a cockroach has a confident gait, although it sways a little from side to side. However, this is not so important. The main thing is that the mechanics in this case are as simple as possible.
The main components and the method of their fastening
Homemade mechanical cockroach has a vertical arrangement of mechanisms that are assembled on a 6 mm thick plexiglass frame. This design allows you to set your head on the front axle of the legs, as a result of which the cockroach not only moves along a given path, but also carefully inspects the road.
The "insides" of a cockroach is a small electric motor, two plastic gears, a crank axis and traction. The cockroach eats from the ordinary finger-type battery. For more details on how to make such a funny toy, see the video on the site.
