Droid 2

From KeenWiki

This hopping robot's primary function is to guard the Robot Hive, but it does other menial work during its off-duty hours. Don't drop your guard around this mechanical menace as it will bound toward you and smush you into the ground. Takes two hits, one to stun and disarm, the next {A pogoing) to bust it to bits. Unlike Droid 1 it can see where you are and will follow you about. It is a variety of Droidiccus.
