Space Browsers: A Tool for Ubiquitous Tele-embodiment
The first PRoPs were simple airborne tele-robots we named Space Browsers first designed and flown in 1995. The Space Browsers were helium-filled blimps of human proportions or smaller propelled by several lightweight motor-driven propellers. On board each blimp was a color video camera, a microphone, a speaker, and the electronics and radio links necessary to enable remote operation. The entire payload was less than 600 grams (typically 400-500 grams). We used the smallest blimps that could carry the necessary cargo in order to keep them as maneuverable as possible. Our space browsers ware able to navigate hallways, doorways, stairwells, and even in the confines of an elevator. We experimented with several different configurations, ranging in size from 180×90 cm to 120×60 cm and shapes from cylinders and spheres to “pillow-shaped” rectangles. We found he smaller blimps were best-suited for moving into groups of people and engaging in conversation with minimal disruption since they took up no more space than a standing person. The browsers were designed to move at a speed similar to a human walking.
