Evolving and Controlling Behaviors in a Computation-Free Robot Swarm
Flocks of birds, schools of fish, and colonies of ants exhibit a remarkable robustness and resilience, despite the limited capabilities of each individual. Recently, research into bio-inspired swarm robotics has been gaining popularity due to the low-cost, robust, redundant, and...
Briefs: Test & Measurement
A component leak test apparatus investigates the performance of fittings at low temperature and/or high pressure. Its performance was quantified by measuring the ability to hold cold pressurized gaseous helium (He)...
Briefs: Semiconductors & ICs
A collective rattling effect in a type of crystalline semiconductor was discovered to block most heat transfer while preserving high electrical conductivity — a rare pairing that...
