Elevated Robotic Assistive Device
Simply put, there is more “open real estate” available overhead than on the floor for many types of mobile personal assistant robotics.
The ERAD (Elevated Robotic Assistive Device) technology* is centered about “mobile robotic assistive devices that don’t take up floor space.” While floor-based mobile robots (e.g. telepresence devices) may have great potential for automating processes and assisting people (i.e. the disabled and infirmed or home/industrial security), their need to navigate around objects (people, furniture, stairs, pets..) renders them expensive while still not alleviating the potential for a sense of obtrusiveness on the part of the users.
