Bohr model

In 1931, the Bohr model has been proposed by Niels Bohr to explain how electrons can have stable orbits around the nucleus. The electrons travel around the positively charged nucleus in orbits of fixed size and energy. The energy of an electron depends on the size of the orbit. The orbit closest to the nucleus has minimum energy and the orbit farthest has maximum energy. In this artwork, colors are used to represent the energy level of the orbit of electron. White, yellow, green, blue, red and black are used to paint the artwork. We use round brush size 1 mm. It takes approximately 60 minutes to use a paint brush for this artwork. The total haptic file (position and force data) sizes for recreate artwork are about 820.973 MB. We present haptic human-robot collaboration system based on master-slave delta robot. The turntable robotic is also specially design to rotate and to control speed of the drawing pad. We first use the bilateral control with motion copying system to record both the interaction force and position responses from artist. We then use the motion replaying system with haptic processing to recreate artwork. The proposed human-robot collaboration system enables robot not only to recreate artworks, but also to improve their performance from the force and position data processing.
