Product description
[4000156349067]Have you seen an art-filled robot? It has a flying saucer-like body, but three long hands can draw a variety of patterns. It is not easy to learn to draw the same graphics.
Now you can also assemble a graffiti robot yourself, which can help you draw a Picasso-like work. Every blessing is different. It is definitely not a dream to be a talented painter.
The graffiti robot contains:
1 base plate, 1 transparent cover, screws and bolts, 1 generator (with wire), 1 engine cover, 1 heavy object, 3 support arms, solid pen, 3 arm ends, adhesive label, 2 Terminal cap, screw, 3 felt pens
Suitable age: 8 years old or older
The principle of graffiti robot
The robot is powered by the battery to let the motor rotate the weight of the weight. The center of gravity of the weight moves to one side and does not match the motor shaft. When the weight rotates, the chassis is driven in the opposite direction, the motor and the chassis vibrate at a high frequency in a small circle, and the nib also vibrates under the paper surface. When the nib leaves the paper, the vibration of the spiral causes them to move. If the nib does not vibrate up and down, the friction between the nib and the paper will cause the robot to stop moving.
Interesting facts
Industrial robots that move, cut and combine materials can be programmed to draw on paper.
Swiss scientists create robots that take pictures of a person's face and sketch the image out with a pen on the robot's arm. Using simple programming languages such as forward, backward and turn, the turtle educational robot can be programmed to draw geometric shapes. The vibration principle is applied to many industrial machines. For example, a substance, such as a powder, is vibrated up and down at a high frequency on a conveyor belt for the purpose of delivery.
