Principle of operations
The robot is steered by a joystick at the control box of Duct Control Manual or Mini. At the joystick
box is also a switch button for the camera
’s LED lights. Brush rotation direction and lifting arm height
control is done manually on the robot itself.
Duct Control Cleaning robot can be used to inspect both circular and rectangular ducts.
Camera
The view inside the duct is seen from the TFT monitor. The angle of view can be adjusted manually:
loosen the tightening screw and tilt the camera into desired position, then lock the angle by tightening
the screw again.
The lights of camera can be adjusted, or the camera automatically reacts to lightning.
Video can be recorded on a separate standard SD card recorder (not included) through a RCA
type/analogue output. It is also possible to view the recording from the TFT display. Alternatively, the
view can be recorded on a laptop PC computer by using a video grabber picture card (accessory)
that converts analogue video signal to digital through USB 2.0 feature.
Please, read the separate instruction manual from the manufacturer for both the
TFT monitor and video grabber picture card recommended by Lifa Air Ltd.
Driving
Before any operation, train yourself by driving on the floor and under the furniture to be able to control
the movements of the Robot.
Hold the Joystick Box with your both hands and push the joysticks forward. The Robot will then crawl
straight forward. It is to be backed/reversed by pulling the joystick backwards. Turning is done by
switching the joystick crosswise.
The accessory extra weight (not included) gives additional grip for the wheels, when driving out the
full length of the cable.
When you feel ready-to go, put the Robot in the duct through an access door or other suitable
entrance for the equipment. Adjust the light according to the darkness and reflections in the duct.
Drive smoothly forward looking the view inside. Be careful about the possible sharp edges and
screws, which are a risk for the cable and the whole robot might get stuck when the cable tangles
around such object!
If the Robot gets stuck in the duct, do not pull it from the cable aggressively in order to avoid damaging
the cable! Try to drive the robot forward and back and gently draw the cable at the same time. If not
succeeded, you may have to cut an extra access opening to the duct to collect the robot or use a
glass fiber rod to catch and release the stuck Robot/Cable.
