The US Researchers have built the swarm robots with a 3D printer. The researchers took inspiration from the ants and honeybees. The ability of the ants to help each other and remove any obstacle together motivated the engineers. The four-legged robots are 15 to 20 centimeters in length. It looks like an ant. Each robot can connect with the help of sensors and microcontrollers. They can carry out the job of monitoring and searching for an object. They can also establish a communication network. They can also work together to overcome any obstacle. These swarm robots would help in solving big problems. It would be interesting to watch them carry out the job.
