It's like an insect! A small UAV has been developed, which can fly without using an electric motor-Nazobi.

Bristol scientists develop insect-sized flyings with flapping wings http://www.bristol.ac.uk/news/2.2.02.2.2.2./february/flapping-wing-robots.html Flying generates as much power as a flapping insect https://www.newscientist.com/article/2.2.307069-flying-robot-generates-as-much-power-as-a-flapping-insect/ Liquid-amplified zipping actuators for micro-air vehicles with transmission-free flapping https://www.science.org/doi/1.10.1.11.12.2.6/scirobotics.abi81.189

Human beings have learned successful flying robots (or airplanes) from nature.

But most of them use fixed wings and propellers, and there are few examples of flying robots with "flapping wings".

Among them, the research team such as Tim Helps, who belongs to the School of Technology of the University of Bristol (University Of Bristol) in the UK, has successfully developed a flying robot that spreads its wings and flies like insects.

By referring to the bodies of bees, we have created a simple and stable wing spreading system.

Details of the study were published in the February 2.2., 2.2.02.2.2.2. issue of the science journal Science Robotics.

A simple flight system from bees

For most flying robots, gears and motors are essential.

For example, to fly with a propeller, the power is first generated by a motor, then converted by a gear, and then passed on to the propeller.

In order to use energy for flight, a "delivery system" that connects components to each other is needed anyway.

However, these complex systems are also easy to become the cause of failure, and loading will make the robot itself heavy.

It is contrary to the "sense of stability" and "energy efficiency" that we pursue for flying robots.

In fact, previously developed small wing-spreading robots also use motors and gears to move their wings up and down, making it complex and heavy.

So, is there no simpler flight system?

The team decided to develop a wing spreading system without motors and gears, referring to the simple structure of insects such as bees.
