A team of researchers at New York University's Tandon School of Engineering has made a significant breakthrough in robotics by developing a robot called 'WorMa'. This innovative robot is capable of moving in various environments without the need for changing its parts or using specialized limbs for each surface. The robot's name 'WorMa' is derived from the words 'worm' and 'module', reflecting its ability to move like a worm.
WorMa's movement is inspired by the way worms and snakes move, but it also features a system that allows it to redistribute its weight internally according to the surrounding environment. The robot measures approximately 50 centimeters in length and consists of five joints and four links, weighing just over one kilogram. Its unique design enables it to crawl on land, climb slopes, and even swim in water.
The robot's movement is made possible by a system that involves transferring water between two flexible latex reservoirs, one located in the head and the other in the tail. A pump in the middle of the body transfers around 300 grams of water between the reservoirs, which is equivalent to about 28% of the robot's total weight. By changing the distribution of water, WorMa can adapt to different surfaces and environments.
Experiments have shown that placing water in the head of the robot is most effective when climbing steep slopes, allowing it to overcome a slope of 19.5 degrees while reducing energy consumption by at least 33%. On the other hand, transferring water to the tail enables the robot to swim faster and more efficiently, increasing its speed by 26% and improving its movement efficiency by 52%.
WorMa's ability to adapt to different environments makes it an ideal solution for amphibious robots that can operate in both water and on land. Unlike traditional robots that require different limbs or mechanisms for each environment, WorMa's internal water transfer system allows it to navigate through diverse terrains, including flat surfaces, slopes, stairs, and water.
The researchers believe that WorMa's technology has the potential to be applied in various fields, such as coastal monitoring, wetland exploration, and inspection of infrastructure in complex environments. The development of more advanced robots like WorMa could lead to significant breakthroughs in robotics and provide innovative solutions for real-world problems.
