Modular robots are the future of the industry. By essentially splitting the overall function of any robot down into simple and configurable building blocks, you can create a wide array of robots through a process very similar to building with LEGOs.
The biggest problem with rigid robot systems is their inability to adapt to new and unexpected environments. Through a system of configurable and reconfigurable robots, the tech is able to adapt and overcome. Take a look at just what these little robots can do in the video below!
