1. 🐝 The World of Micro Robotics
- Micro robots exist that are the size of bees and others can jump on water; some are powered by tiny combustion engines the size of a penny.
- These robots could potentially work in swarms, save lives, or even be used for surveillance.
- A tiny robot submarine can move by flapping wings nine times per second underwater and 250 times a second in the air, showcasing dual functionality in flying and swimming.
- The robot weighs 175 milligrams, similar to two Cheerios, and faces challenges with surface tension due to its small scale.
- Another robot, weighing just 68 milligrams, uses a spring mechanism mimicking a flea's leg to jump on water without breaking the surface, similar to a water strider.
- The submarine robot uses gas buoyancy to lift fragile parts out of water before its wings flap, preventing damage, and utilizes a gas explosion to break surface tension and achieve flight.
- A different robot uses water-repellent copper pads for walking on water and applies 600 volts to break the surface tension, allowing it to dive and walk underwater.
