This particular Robot with no unique designation was invented by Dexter in the episode "Sdrawkcab" to manage the lever that controlled his Backwards Belt. The Robot took Dexter's orders quite literally which resulted in Dexter getting somewhat annoyed and he proceeded to order the robot to remind him to never oil him again, much to the Robot's disappointment. Later on it disappeared and Dee Dee took control of the Backwards Belt lever, likely having been destroyed by her or having left due to Dexter's mistreatment. It was voiced by Jeff Bennett.
- It is simply referred to as the "Robot" in the credits.
