Improvements in force sensors will allow the next generation of service robots to perform simple service tasks, such as clearing tables and fetching coffee.

Prototypes are able to pick up bottles and cups without gripping too hard, and separately steered and powered wheels permit them to successfully negotiate tight spaces, such as a narrow apartment kitchen.

Researchers have created a Care-O-bot® 3 model that also recognizes and responds to voice commands. Unfortunately, these domestic helpers are not yet at the level of dishwashing and floor waxing like Rosie, the dutiful robot maid from "The Jetsons."

We're thinking the gentle gripping sensors will also help speed the development of robot hookers, a technological advance we continue to follow very closely.
