EMRoS (Epson Micro Robot System)

Seiko Epson Corporation, Japan, began the design of a series of microrobots, the EMRoS, starting in 1993. They are all mobile robots that chase a light source. At the time, they were the world's smallest mobile microrobots (approx. 1cm cubed).
This set contains two microrobots, dates from about 1995, and represents the fourth type of EMRoS. The robot shell is made of silver. Inside of each are about 98 parts, many of which are based on watch components, a strength in Seiko's product lines. Each robot has two "eyes" sensitive to light. A flashlight, included in the set, can be used to attract the robots. Instead of battery power, each robot receives a charge from its container that allows it to run for some minutes. The robot's whiskers provide the electrical contact to the charging station.
Seiko Epson originally designed and built the micro robots as a research project, but then made a limited edition of each generation for sale at about $500 per set for entertainment purposes.
