Mechanical devices are operated by the pneumatic and the controllings are achieved by the microcontroller boards. Suction cups are fitted to end of the cylinders and piston rod in order to achieve the cling movement.Suction cup are creating a vacuum between the cup and wall due to that a machine can able to achieve cling movement to the wall.
Project Description:
PNEUMATIC CYLINDER AND PISTON:Its a mechanical device which converts the air pressure into the linear motion.This is the main part of the robot which helps to move the machine on the wall.Both are fully controlled by sending the air at a particular time to achieve the suction by the cups fitted at the end of the cylinder and piston.
VACUUM CUP:Its widely used for robotics industries for handling the light materials.Mostly its comes in conical shape.It uses vacuum cups as the gripping device, which is also commonly known as suction cups. This type of grippers will provide good handling if the objects are smooth, flat, and clean. It has only one surface for gripping the objects. Most importantly, it is not best suitable for handling the objects with holes.
ELECTRONIC CIRCUIT:It is used for controlling the robot by obtaining the smooth cling movement.It has a microcontroller which can be programmed for getting different type of output motion.
VACUUM EJECTOR:It is a device which takes the compressed air through its nozzle and sends the air to the vacuum cup.After passing through the nozzle, the accelerated air slows down once again and a vacuum is created. Air is drawn in this way through the vacuum connection. The aspirated air and the compressed air escape through the silencer.
ELECTRIC VALVE:Its a electromechanical device which uses the solenoid valve for stopping and allowing the air.Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power.
Project Implementation:
Fix the vacuum cup at the end of the pneumatic cylinder and piston rod. Then fix the pneumatic cylinders in plus configuration and connect the air pipes from the cylinder to electric valve.Make the wire connection between electric valve and the microcontroller. Connect the air pipe from the electric valve to the compressor. Now power the microcontroller board using the battery or DC adapter.Now place the robot to the wall then it will start to move by cling action.
