A robot is disclosed. The robot can comprise a body comprising a curved base and a multi-directional center of mass shifter assembly positioned within the body. The multi-directional center of mass shifter assembly can comprise a weight, a first actuator drivingly coupled to the weight, and a second actuator drivingly coupled to the first actuator. Actuation of the first actuator can be configured to rotate the weight relative to a first axis, and actuation of the second actuator can be configured to rotate the weight relative to a second axis, which is transverse to the first axis. The robot can comprise an inertial measurement unit, a controller, and/or an eye movable relative to the body. The position of the eye can be adjusted by an eye actuation assembly.
