a series of droids designed by Lovolan, the R-10 was designed to work in households as party waiters, bartenders and drink mixers. They stood about a meter tall, and were box-shaped. Their top was made of a slab of marble surrounded by a brass railing. The marble top was specially charged so that drink glasses placed on it do not move around during transport. Four small casters allowed the R-10 to move in any direction smoothly, while a number of retractable manipulator arms allowed the R-10 to effortlessly mix any number of drinks. Also, the R-10 was programmed with routines that made it impossible to spill a drink or drop a glass.
