5.3. Pre-use inspection
To ensure proper working and safe condition of the SR 450 StairRobot:
•
Check that no rubber blocks on the tracks are severely damaged or torn off
•
Check the drive-tooth side of the tracks for exposed stringing cords or damage
•
Check that nothing has been trapped between the tracks and the robot
•
Check that the batteries are fully loaded (battery charge indicator)
•
Check that the castor of the folding wheel moves free
•
Check that the two fixed wheel can move free
•
Check that the lever of the folding wheel permits the folding wheel to drop and lock in
its position for horizontal moving
•
Move the control handle left and right causing the tracks to move forward and
backward, listen for excessive sounds ;If a defect is found do not use the machine
until the Stair-Robot is repaired.
•
Unlock the handle of the extension frame and check if the extension frame will move
up and down
If there are no defects found the machine is ready for use. If a defect is found do not use the
machine until the Stair-Robot is repaired.
5.4.
Loading
5.4.1. The correct position of the load
•
If the load is not placed in the correct position on the platform,
the Stair robot can get instable during the process of climbing or
descending a staircase. This can cause the robot to fall down
the stairs resulting in serious damage and injuries.
•
The objective is to create an optimal centre of gravity position for the loaded stairrobot
considering the ‘weight distribution’ of the load
•
Before positioning the load on the
platform the centre of gravity of
the load has to be determined
