5.1.5 Limits of current system
The inexpensive hall-effector’s sensors mounted to the back of the robot were unable to provide a stable quadrature signal in the current version of the robot. This restricted the possibility for making the robot autonomous. During the play test studies with children, however, the choice to have a research assistant teleoperate the robot helped acquiesce any parental concerns about
the robot’s safety around children. As the robot is currently being localized through the motion capture system, a location vector as well as an orientation (heading) quaternion are given, enabling future development of semi-autonomous behavior.
