Mori3 - Rolling loop
The Mori3 is a robot capable of changing its own shape to adapt to new environments and unseen tasks. The Mori3 consists of autonomous pieces which can connect together to form large, complex, and moving systems.
This video shows ten modules connected as a loop, rolling across the floor.
Each module can change the length of each triangular edge. When all edges on a module are identical, the loop rolls in a straight line, like a cylinder. Extending all the edges on one side of the loop changes the system to resemble a cone, allowing the robot to steer around corners, without having to disconnect and reconnect modules.
