The first Care-O-bot® prototype was built in 1998 and was already able to navigate autonomously and safely in indoor environments, communicate with or guide people.
Care-O-bot® II, built in 2002, was able to manipulate simple objects found typically in home
environments. It was equipped with a manipulator arm, adjustable
walking supporters, a tilting sensor head containing two cameras and a laser scanner, and a
hand-held control panel.
