Path of the Moon through Earth's umbral and penumbral shadowsA total eclipse of the Moon occurs during the early morning of Tuesday, August 28, 2007. The event is widely visible from the United States and Canada as well as South America, the Pacific Ocean, western Asia and Australia. During a total lunar eclipse, the Moon's disk can take on a dramatically colorful appearance from bright orange to blood red to dark brown and (rarely) very dark gray.
An eclipse of the Moon can only take place at Full Moon, and only if the Moon passes through some portion of Earth's shadow. The shadow is actually composed of two cone-shaped parts, one nested inside the other. The outer shadow or penumbra is a zone where Earth blocks some (but not all) of the Sun's rays. In contrast, the inner shadow or umbra is a region where Earth blocks all direct sunlight from reaching the Moon.

ROBOTIS(www.robotis.com) is the very developer of its actuators ‘Dynamixel’ that 28 humanoid robot teams participating in ‘RoboCup 2007’ adopted.
Dynamixel is a high-performance actuator controlled by digital packet communication. It has unique ID controlled by Packet communication on a bus. It supports network of TTL, RS 485, and CAN, etc. depending on model. The Dynamixel can read current position of it or speed as well as various information such as internal temperature, supply voltage, target position.
Featuring simple connection structure, it gives you feedback when internal temperature, torque, supply voltage escapes from appointed range. Also in such emergency situation, it flashes LED.
