Robot stabilizer system and/or method therefor

A system, comprising:

• a frame comprising a sleeve bearing, the sleeve bearing defining a central axis;
• a wheel mounted to the frame;
• and
• an actuator mechanically coupled to the frame and actuatable along the central axis;
• a foot;
• and
• a linkage mechanically coupling the actuator to the foot, the linkage comprising:
• a leg arranged within the sleeve bearing and actuatable relative to the sleeve bearing along the central axis, wherein the leg defines, along a single kinematic chain:
• a first joint superior to the sleeve bearing, wherein the actuator is coupled to the leg at the first joint;
• a threaded interface arranged axially along the central axis, wherein the threaded interface defines a manual actuation stroke parallel with the central axis;
• and
• a second joint inferior to the sleeve bearing, wherein the foot is mechanically coupled to the leg at the second joint.
