Switzerland has developed an Omni-directional codecamper

Dual rotors on the swivel arms allow the drone to hold a steady position.

Swiss engineers have developed and tested an Omni-directional codecamper designed for contact inspection facilities. Dual rotors on the rotary shoulders allow the drone to hold a steady position when applying force to the surface to be examined, informs US.Media.

The vast majority of multicopters, despite the maneuverability, do not cope well with the force applied parallel to the plane of the screws-the drone is easy to get out of balance by simply pushing to the side. In recent years, drones have begun to be widely used for inspection of various structures: steam boilers, cell towers and bridges (there is even a drone that looks into the hollows). However, in all these cases, we mean only contactless review, and when the risk of a collision with a large surface of the drone, it is protected by a special body.

However, in some cases, visual inspection is not enough, including the inspection of concrete structures, engineers are developing various ways to improve the stability of drones. This is done both programmatically (for example, teach aggressive maneuvers) and hardware, experimenting with the design of the drone.

Engineers from ETH Zurich have built omnidirectional codecamper. The 12-rotor drone is built on a hexacopter frame with twin rotors, with a rotating drive on each arm of the frame, allowing the multilet to change the thrust vector of each pair of rotors independently.

On the frame of the multilet there is a separate shoulder of effectors for contact with the surface. The developers tested the dodecopter in several scenarios, including pulling the rope, forcing the wheel to roll along the ceiling and repeat the same line on the Board with a marker, and also tested the concrete by the method of electric potential, showing rusty reinforcement. In all scenarios, the drone showed high stability in flight.

It is worth noting that this is not the first Omni-directional multilet, two years ago was presented commercial hexacopter Voliro, which was also developed by engineers from the Swiss higher technical school of Zurich, but it used single rotors and there was no additional “hand” to install the equipment. At ETH Zurich, often experimenting with drones: they taught the quadcopter to flip with a pole, and established a rope crossing using quadrocopters, as well as built a drone-ring and asymmetrical single drone.
