In task 1, a child was initially located at position 5 and was
asked to move to position 4. Once the child drove the robot
successfully from position 5 to position 4, the caregiver relocated
the robot to position 6 for the next path within task 1. The
caregiver then encouraged the child to move from position 6
to position 2.After the child completed these two paths of task 1,
the child moved on to task 2. For task 2, the first path was to
go from position 6 to position 1. After the child succeeded,
the robot was repositioned at 6, and the child was urged to
move toward position 3. A caregiver relocated the child to the
initial position, if she/he failed in the given task. In addition,
the caregiver joystick was used to stop the robot if the child
was moving unsafely in the room.
