Video: Robot moves on all surfaces

Without the need for gravity to grasp the walls and ceilings, a new robot takes advantage of the fast-moving air stream, creating gravity on any surface.

This robot was developed by researchers at the University of Canterbury (New Zealand), based on the dynamic principle of Daniel Bernoulli.

According to Bernoulli's principle, when a fluid (like air) moves faster, its pressure decreases. Researchers have created clamps that are only 25 μm apart around the rim of the wheel to create high-velocity airflow.

This design helps compress the air flow to the point of reaching the ultrasonic speed. The airflow is fast, creating a low-pressure vortex inside the clamps, powerful enough to pull the robot moving across surfaces, like walls or ceilings, without touching the surface. This robot can roll on two wheels, but the clamp is still a small distance from the surface.

Bernoulli's former handles are used to lift lightweight items, especially fragile ones. But researchers have to carefully design the gap between the grips to increase the strength of grips by 5 times without relying on air pressure.

Non-contact grips can be used in many industrial applications, and will be used in the near future.
