emBeds — also known as service bots or just bots -- were androids that were fairly commonplace in Aisha's world, even prior to her own self-discovery. They were manipulated by the students of Merced Tech with such regularity that students like Cari often failed to notice them. Aisha was made sad by them when she saw them unassembled.
Dr. Sharon Carter regarded them as lesser inventions to Aisha, whom she called a unique piece of artificial intelligence. Indeed, it was easy to recognise emBeds like William and Emma because, amongst other reasons, they had obvious join marks on their faces.
