  • The purpose of a solar engine is to act like a power "savings account" -- a small trickle of incoming energy is saved up until a useable amount is stored
  • A solar-powered robot can be made to work, even in relatively-low light levels
  • Solar cell size is minimized

    At the heart of most solar-powered robots is a circuit called the solar engine (variously called Solar Engines, solarengines, SEs; a.k.a,relaxation oscillators). The purpose of a solar engine is to act like a power "savings account" -- a small trickle of incoming energy is saved up until a useable amount is stored. This stored energy is then released in a burst, in order to drive some useful (if only sporadic and incremental) work.

  • 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.

beam electronics solar

shared by York Jong on 26 May 07 - Cached
  • A device used to store charge in an electrical circuit. A capacitor functions much like a battery, but charges and discharges much more efficiently
  • BEAM robots tend to use capacitors in two, very different roles -- small ones in Nv neurons and solar engines (filter capacitors), and bigger ones as energy storage devices (storage capacitors).
