From Ground to Hole

Flying and Docking

The Quadcopter flies to the operation site. A power cable from the ground supplies the Quadcopter with the necessary energy. While approaching the wall the vacuum pumps are turned on so that the Quadcopter can dock to the wall with the suction cups. Now the propellers can be turned off, as the weight is fully supported by the suction cups.


The drill must be aligned perpendicular to the wall. To do this, the joints are loosened, which allows the body of the quadrocopter to rotate. With the help of the propellers, the body is turned 90° towards the wall. The joints are then locked again to prevent it from tipping back.


A positioning system is mounted on the quadcopter, which allows the drill to be positioned on a field of 60 by 60 centimeters. This compensates for inaccuracies during the approach.This not only enables the platform to drill precisely but also to do multiple operations without having to reattach.


For the drilling high forces upto 100N are required, in order to induce such power the propellers are turned on again and push the drone towards the wall. An onboard camera and laser system gives feedback to the operator in order to check whether the hole is at the correct position. A readjustment is possible anytime.

Return to ground

Now the hole is drilled and the drone needs to get back to take off position. The propellers rotate backwards, causing the body to move away from the wall again. Subsequently, the body rotates back to the flight position. This rotation is also driven by the propellers. The Quadcopter is ready for take off,  pumps are deactivated, valves opened and the operator flies the QC away from the wall. Now the quadcopter lands on the ground again and is ready for the next mission.

Technical Specifications

Capable of holding up to 50 kg, the attachment system allows the transition from an aerial robot to a temporary access solution. Depending on the surface properties, different suction cups guarantee reliability and robustness.

Working on all surface orientations is made possible through rotation of the attachment system. The central tool position improves flight characteristics and the propellers can be used to generate large forces.

Only precise work is good work! Together with absolute position data, tools and sensors can be positioned exactly where they need to be. Millimetre-level precision, every time.

Capable of carrying 6 kg of payload, most power tools can be used quickly and safely. Up to 200 N of force allows for human performance and guarantees successful operation. Sensors can be glued, screwed or attached with minor modifications.

A standard flight frame and standard controls allow for easy deployment and minimal instruction. Even unskilled pilots can operate the robot quickly and perform the work as needed.
