“…Service robots include commercialized domestic machines, such as self-navigating vacuum cleaners and mops (Kuzma, 2006), but also robotic pets that apply pet therapy principles to assist older people to maintain mobility and stay active when having real pets is not an option (e.g., due to a residential policy or the inability of a resident to continuously care for a pet) (Carelli, Gaggioli, Pioggia, de Rossi, & Riva, 2009).

The majority of robotic studies in the home focus on lower-limb "exoskeleton" technologies.…”
