Technical Problems With "Programmable self-assembly in a thousand-robot swarm"
This addresses the problem of scalable and robust self-assembly in robotics for researchers, but it is incremental due to noted limitations in motility and shape complexity.
The paper tackles programmable self-assembly in a swarm of 1000 Kilobot robots, advancing artificial swarms with high robustness, but it results in limitations such as poor motility and inability to form complex shapes with holes, reducing practical similarity to living systems.
Rubenstein et al. present an interesting system of programmable self-assembled structure formation using 1000 Kilobot robots. The paper claims to advance work in artificial swarms similar to capabilities of natural systems besides being highly robust. However, the system lacks in terms of matching motility and complex shapes with holes, thereby limiting practical similarity to self-assembly in living systems.
