Engineers at the Univ. of Southern California have built a flying insect based on the anatomy of a bee. Called the Bee Plus robot: the nature-inspired flying bot weighs 95 milligrams and is the size of a penny.

The tiny bot is similar to Harvard University’s popular RoboBee project from year 2013. RoboBee had 2 wings, Bee Plus has 4 wings — like a real insect. The added wings gives the bot more life-like flying abilities. Each of the wings is driven by an actuator that’s simpler and lighter that the ones used by for RoboBee.

The prototype brings together collective knowledge from: robot design, control theory, aerodynamics, and micro-fabrication. Bee Plus can perch, land, swim, follow a path, and avoid obstacles.

The engineering team lists a range of potential uses for Bee Plus:

  • artificially pollinating flowers
  • robotic swarm research or search + rescue missions
  • taking geological samples
  • measuring gases in the atmosphere
  • surveillance on planet Mars + moons

To achieve these dreams, the researchers will need to overcome this limitation: Bee Plus can only fly when it’s tethered to a power source. They’ve developed a possible solution called ‘‘catalytic artificial muscles’’ — a new type of actuation technology.

by definition | actuator

An actuator is a part of a machine responsible for moving + controlling a mechanism or system — for example: by opening a valve. In simple terms, it’s a ‘‘mover.’’ An actuator requires a control signal plus a power source. Its power may be an electricity, hydraulic (fluid) pressure, or pneumatic (gas) pressure.

An actuator is a mechanical device takes the movement of its power source (the current of electricity, the pressure of gas or fluid) and directs it — like a steady stream — to move something. It also can be used to apply force. That motion can be any form — such as: blocking, clamping, or ejecting. Actuators are used in robotics and manufacturing — and in devices such as: motors, pumps, switches, and valves.

Developing miniature actuators to move robots the size of an insect — such as robot bees + robot hummingbird — is an engineering challenge.
