With it’s cheap parts, the tiny one ounce lithium battery powered jumping robot can be used for anything from rescue & surveillance operations to dealing with oil spills.
Inspired by the locust’s jumping mechanism and elastic energy storage, Tel Aviv University researchers designed a tiny robot which could prove to be an inspired leap into the future of autonomous surveillance and emergency response systems.
Made from carbon rods, steel springs and 3D printed plastic pieces, it weighs less than one ounce (23 grams) and is approximately four inches (10 centimeters) long.
“The locust being a large insect that has wonderful jumping performance had offered itself as wonderful inspiration for this specific idea of a jumping…miniature jumping robot,” lead developer Professor Amir Ayali, of the Department of Zoology at Tel Aviv University’s Faculty of Life Sciences, told Reuters as he inspected a locust grown in his laboratory.
The robot can jump a remarkable 11.5 feet (3.5 meters), said Ayali, due to its structure and energy storage, which along with its motor makes it capable to withstand high accelerations.
“The locust uses mechanical energy in addition to its muscle force in order to generate a jump and this is exactly what we are imitating…We are using a tiny motor that generates, or stores mechanical energy, and this mechanical energy in springs is actually very similar to the locust legs is what propels the robot into the air,” said Ayali.
The bio-inspired robot, dubbed ‘TAUB’ (Tel Aviv University and Ort Braude College) was born out of an interdisciplinary collaboration between engineers and zoologists at the bequest of the Pearls of Wisdom Association for Research and advanced technology development in Israel.
Unlike drones that can be airborne for up to about 30 minutes, the locust robot is powered by a lithium battery. With its energy efficiency it can reach up to 1,000 jumps with only one battery loading.
Ayali said the robot could be easily mass produced since its parts are cheap and it is easy to manufacture, estimating the price of a robot at $100 USD.
From oil spills to rescue and surveillance operations, “what you do with it is whatever is needed whenever you want to engage any kind of robotic system with no human interference,” he said.
Ayali believes that with sufficient knowledge of locusts’ swarming capabilities, the robots may be capable of implementing the mechanisms of swarming capabilities in robotic systems.
Hungarian-born Doctor Gabor Kosa, of TAU’s Faculty of Engineering, a confessed sci-fi fan, envisages a swarm of robots installed with GPS navigation systems, cameras and solar panels for powering, entering enemy territory to carry out a surveillance operation.
Around $200,000 USD was invested in the project at its early stages. Ayali says the team is seeking more funding to develop it further.
