Untethered, downhole robots are described. In some cases, the downhole robots are configured to have a density within + or −20% of wellbore fluid in which it will be operating. In some cases, the downhole robots a controller capable of discerning deviation of the wellbore from vertical and, in response, control a buoyancy system to change longitudinal distribution of the weight of the robot, wherein the magnitude of the change in the longitudinal distribution of the weight suffices to reorient the robot.
