#1. UNPREDICTABILITY. "First reason for this is parallelization. Even simplest programs, when run on many processor cores, start to behave in non-deterministic way. The reason for this is that different cores compute with slightly different speeds and each time the sequence of computed tasks might differ." https://lnkd.in/dWhwFiV View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and ends this weekend on the theme of the evolution of complexity. The popular culture, overlaid by 2,000 years of religious thinking, has some deep-set ideas about the topic, summarized in the inexorable drive of nature towards complexity and perfection based also on a hierarch of being. But nature is nothing but full of exceptions and surprises, and close examination soundly whacks this set of assumptions into the oblivion. View in LinkedIn

LESS DIFFICULT. "In some instances it may actually be easier or cheaper to design cooperative teams of robots to perform autonomous systems" in emergency applications.” https://lnkd.in/e3yjqqd View in LinkedIn

"THE MARTHA PROJECT objectives are the control and management of a fleet of autonomous mobile robots" or multi-robot collaboration in difficult and unexpected terrains.” https://lnkd.in/ef8ANkk View in LinkedIn

ROACHBOTS. "The other thing to reiterate is how simple and cheap these roachbots are, and if you can use a bunch of them to mimic (or even improve upon) the functionality of larger and more expensive robots, you could save a lot of time and resources by relying on them instead." http://spectrum.ieee.org/automaton/robotics/robotics-hardware/robot-roaches-with-tiny-magnetic-winch-cooperate-to-scale-steps View in LinkedIn

ROBOT SWARMS. "We’ve been fans of heterogeneous robot swarms for a long time, and it’s very cool to think about how teams of VelociRoACH robots might be able to work with teams of quadrotors like this." http://spectrum.ieee.org/automaton/robotics/robotics-hardware/robot-roaches-with-tiny-magnetic-winch-cooperate-to-scale-steps View in LinkedIn

"THE TETHER-ASSISTED climbing mode fills in the last piece of the step climbing strategy— instead of just sending one member of the team up the step after climbing while connected, the winch can be used to pull the other team member up the step as well." http://spectrum.ieee.org/automaton/robotics/robotics-hardware/robot-roaches-with-tiny-magnetic-winch-cooperate-to-scale-steps View in LinkedIn

MODULAR ADVANTAGES. "The cooperating robots benefit from distributed actuation of modular robots to climb steps, while being able to break the modular robot up when it is too cumbersome to drag the connected robots up the step." http://spectrum.ieee.org/automaton/robotics/robotics-hardware/robot-roaches-with-tiny-magnetic-winch-cooperate-to-scale-steps View in LinkedIn

SCALING. "Planning under uncertainty faces a scalability problem when considering multi-robot teams, as the information space scales exponentially with the number of robots." https://lnkd.in/djgRXCW View in LinkedIn
