The thirty fifth convention on Neural Info Processing Techniques (NeurIPS2021) featured eight invited talks. On this submit, we give a flavour of the ultimate presentation.
The collective intelligence of military ants, and the robots they encourage
Radhika Nagpal
Radhika’s analysis focusses on collective intelligence, with the overarching purpose being to know how massive teams of people, with native interplay guidelines, can cooperate to attain globally advanced behaviour. These are fascinating techniques. Every particular person is miniscule in comparison with the huge phenomena that they create, and, with a restricted view of the actions of the remainder of the swarm, they obtain placing coordination.
Taking a look at collective intelligence from an algorithmic point-of-view, the phenomenon emerges from many people interacting utilizing easy guidelines. When run by these massive, decentralised teams, these easy guidelines end in extremely smart behaviour.
The topic of Radhika’s speak was military ants, a species which spectacularly display collective intelligence. With none chief, hundreds of thousands of ants work collectively to self-assemble nests and construct bridge constructions utilizing their very own our bodies.
One explicit facet of research involved self-assembly of such bridges. Radhika’s analysis workforce, which comprised three roboticists and two biologists, discovered that the ants created bridges adapt to site visitors move and terrain. The ants additionally disassembled the bridge when the move of ants had stopped and it wasn’t wanted any extra.
The workforce proposed the next easy speculation to elucidate this behaviour utilizing native guidelines: if an ant is strolling alongside, and experiences congestion (i.e. one other ant steps on it), then it turns into stationary and turns right into a bridge, permitting different ants to stroll over it. Then, if no ants are strolling on it any extra, it may stand up and depart.
These observations, and this speculation, led the workforce to contemplate two analysis questions:
Might they construct a robotic swarm with smooth robots that may self-assemble amorphous constructions, identical to the ant bridges?
Might they formulate guidelines which allowed these robots to self-assemble short-term and adaptive bridge constructions?
There have been two motivations for these questions. Firstly, the purpose of shifting nearer to realising robotic swarms that may clear up issues in a selected setting. Secondly, using an artificial system to raised perceive the collective intelligence of military ants.
Screenshot from Radhika’s speak
Radhika confirmed an illustration of the smooth robotic designed by her group. It has two ft and a smooth physique, and strikes by flipping – one foot stays connected, whereas the opposite detaches from the floor and flips to connect in a unique place. This enables motion in any orientation. Upon detaching, a foot searches by house to seek out someplace to connect. By utilizing grippers on the ft that may hook onto textured surfaces, and having a stretchable Velcro pores and skin, the robots can climb over one another, just like the ants. The robotic pulses, and makes use of a vibration sensor, to detect whether or not it’s involved with one other robotic. A video demonstration of two robots interacting confirmed that they’ve efficiently created a system that may recreate the straightforward speculation outlined above.
With a purpose to examine the high-level properties of military ant bridges, which might require an unlimited variety of robots, the workforce created a simulation. Modelling the ants to have the identical traits as their bodily robots, they have been capable of replicate the excessive stage properties of military ant bridges with their hypothesized guidelines.
