Tele-operators´ judgments of their ability to drive through apertures

It has been suggested that operators should base decisions to enter apertures on their ability to control the robot, rather than its static dimensions. Doing so, however, assumes that operators know whether they can drive a robot through the aperture. The present study tested that assumption. Results indicated that judgments about control of the robot were not accurate. In contrast, judgments of static dimensions were accurate. Thus, operators will require support if they must base decisions to enter apertures on their ability to control that robot.
