Sunset Squad Robot

The Sunset Squad Robot (presumably one of many due to the fact that they're always referred to as "Sunset Squad Robots"), is a robot sent to collect 160-years-olds and return them to the Near Death Star. Specifically, he "collects" Professor Farnsworth in A Clone of My Own. Also, he drives a spaceship that looks like a hearse.

Trivia

 * It is dressed just like the Grim Reaper, a joke on the parallels between death and Near Death Star occupancy.
