  • - [Narrator] A team of researchers

  • from MIT, Columbia, Cornell, and Harvard Universities

  • has developed computationally simple robots

  • that connect in large groups to move around,

  • transport objects and complete other tasks.

  • Made of plastic, magnets and basic electronics

  • each robot in this so called "particle robotics" system

  • is almost static when isolated.

  • Designed only to expand and contract.

  • But when you put a number of these robots together

  • they move in time and the system becomes

  • much more robust.

  • - We are interested in developing

  • the science of autonomy.

  • Particularly when multiple robots work together.

  • And for this reason we designed a robot we call

  • the particle robot.

  • The robot is actually inspired by the idea

  • that natural organisms have cells.

  • And these cells connect together

  • and work together to form larger organisms.

  • And what we would like to do with these robots

  • is study the mechanisms, the principles,

  • and the algorithms that enable

  • these robots to come together to form

  • larger structures that are mobile,

  • that can be used to perform tasks.

  • - [Narrator] Because of their circular shape,

  • individual robotic particles can assemble into

  • many configurations and fluidly navigate

  • around obstacles, squeeze through tiny gaps,

  • and move things along.

  • Uniquely, none of the individual robots

  • or particles as the researchers refer to them,

  • directly communicate or rely on each other to function.

  • So particles can be added or subtracted

  • without any impact on the larger group.

  • - So each of the robots we designed

  • has these magnetic connectors,

  • which will allow multiple particles

  • to connect together at any orientation.

  • And each of the robot can expand and contract.

  • - And so by making and breaking connections

  • and employing expansion and contraction,

  • an individual module is able to help move

  • an entire system of particles in the desired direction.

  • - [Narrator] Traditionally, robots are designed

  • for one purpose, comprise many complex parts,

  • and stop working when any part malfunctions.

  • Robots such as these could enable more scalable,

  • flexible and robust systems.

  • - In our future work we plan

  • to add sensors to this robot to detect

  • the pushing and pulling force of each particle.

  • And we also plan to build a new system

  • made of much smaller particles.

  • - [Narrator] One day they hope to have

  • robotic cells that can be assembled in different ways

  • to make different robots.

  • And perhaps even contain the ability

  • to develop themselves. As the systems goals change

  • it's body could change too.
