  • The basis behavior set of a system provides elements that are not further reducible to each other and that, when composed by sequential or concurrent execution, produce the complete behavior repertoire for the system.
  • Such basis behaviors are constructed, learned, or evolved from stable, robust interaction dynamics between the agent/robot and its environment, and serve as a substrate for the system's more complex behaviors.
  • My work generalized the notion of basis behaviors to multi-robot interactions, and demonstrated how a small set of basis behaviors per robot can be used to demonstrate a rich repertoire of individual and group-level behaviors, including following, flocking, homing, herding, aggregation, dispersion, and formations.

    In 1991 I introduced the notion of basis behaviors, a means for facilitating principled behavior synthesis and analysis in behavior-based systems.

    The word "beam" in BEAM robotics is an acronym for Biology, Electronics, Aesthetics, and Mechanics. This is a term that refers to a style of robotics that primarily uses simple analog circuits instead of a microprocessor in order to produce an unusually s

  • Motorcycle lead acid batteries work great for larger low performance type robots. They are great for solar power robots too.
  • lead acid batteries have the serious problem of being very large and heavy, need to always be kept charged, and do not have the high discharge rates as the more modern batteries.
  • They have low power capacities, are heavy, have trouble supplying large amounts of current in short time periods, and get expensive to constantly replace
  • ...6 more annotations...
  • Li-ion batteries have the same high energy capacity as NiMHs, power output rates of NiCads, and weigh about 20%-35% less. They also have zero memory effect problems, meaning you can recharge whenever
  • NiCad (Nickel Cadmium) batteries are good for small to medium size range robots. They have the highest current output, are more affordable than NiMH's, and can be recharged within one or two hours
  • A NiCad, over many charges, can only store less and less energy after each recharge. To prevent memory effect, whenever you wish to recharge your NiCad, you must first fully discharge it.
  • NiCad batteries contain toxic cadmium stuff, so save a squirrel and recycle/dispose of it properly.
  • NiMH battaries can last many more cycles than your typical NiCad battery.
  • they have good current output, and have the highest energy capacity. I would recommend them for small size robots and for powering circuits. Note, NiMH batteries usually take like 10 hours to recharge depending on various factors.

  • In many ways, both the 74*240 and 74*245 are equally handy for BEAM use; both have 20 pins, and so the main difference that most folks will care about is that one inverts drive inputs, while the other doesn't. Out of curiousity, I decided to torture test the two chips to see how they compared under load.

  • LEDs can be used as photodiodes (tho' their sensitivity is relatively low, so they're only useable this way in very bright conditions). When light is applied to an LED the anode sources current and becomes positive.
