About this program This program combines a servo motor tester and a human-looking robot. A staring robot equals the v1. Check out the previous v1 video to see what kind of robot it is. Parts list The parts list is … more
The three primary colors of light are red, green, and blue. Depending on how these three lights are mixed, different composite colors appear. For better understanding, let’s imagine a three-dimensional coordinate system with the x, y, and z axes. Assuming … more

Parallax When an object is close to me, you can use a ruler to measure the distance. But, it isn’t easy to measure when the object is away from me. In this case, how can you measure the distance? Humans … more
A hypocycloid is a special plane curve generated by the trace of a fixed point on a small circle that rolls within a larger circle. If the radius of a large circle is \(R\), and the radius of a small … more
This is a tool that draws a hypocycloid figure made on a 3D printer. For a description of the hypocycloid, see here(link). 3D print data The gear ratios are 24 for the external gear and 17, 14, and 11 for … more
Why do light and heavy objects fall at the same time? The change in speed due to gravity is the same for all objects because the force and inertia acting on an object are proportional to the object’s mass. The … more
Newton’s cradle Newton’s cradle consists of five iron balls, each hanging on two threads to prevent the ball from spinning. Originally Newton’s cradle was created to demonstrate Newton’s third law. If you collide a ball from one side, the exact … more
