When it comes to designing an advanced environment for robots, scientists often turn to nature for inspiration, especially when it comes to designing an advanced environment. The latest example is an efficient squid robot developed by engineers at the University of California, San Diego, which uses a combination of soft and rigid materials to propel itself through the water, much like the original squid. < / P > < p > the team’s squid inspired robot, shaped like a paper lantern, was designed to store elastic energy in its skin and a set of flexible ribs because it needed to absorb water. The ribs are attached to a pair of circular plates at both ends of the fuselage. One of them sucks in the water around through the nozzle and ejects when the soft body contracts. < / P > < p > this action generates a jet pulse that pushes the robot forward in the water, just like a real squid. This means squidbot can carry power in the body without tether. The scientific progress behind this machine is the first of its kind. In essence, we re created all the key functions of squid for high-speed swimming, said Michael T. Tolley, a professor in the Department of mechanical and aerospace engineering at the University of California, San Diego. &This is the first non tethered robot that can generate jet pulses for fast motion like a squid, and can achieve these jet pulses by changing the shape of the body, thus improving swimming efficiency. &Another advantage of the design is that there is enough space for sensors or cameras to carry out underwater monitoring tasks. This type of soft robot can be used in environmental research projects aimed at protecting fish and corals, otherwise, hard robots may damage them. < / P > < p > the robot was first tested in a waterbed and then tested with other creatures in a larger aquarium. Squidbot clocks at 8 to 32 cm per second (0.5 mph or 0.8 km / h), which the team says is faster than most other soft robots. The team also showed that the robot could steer by changing the direction of the nozzle. < / P > < p > & quot; after we were able to optimize the design of the robot to swim in a laboratory tank, it was particularly exciting that the robot was able to successfully swim in a large aquarium between coral and fish, proving its feasibility in the real world, said Caleb Christianson, who led the study.
