Don't be too hard on the fly's brain. A housefly has about a third of a
million neurons.
If you think of a neuron as being about the power of a transistor - then
there is a computer that's more complex than a 386 - but less complex than
a 486.
If you think of a neuron as being an entire logic gate (which is probably closer
to the truth), then the raw part count is about as powerful as an early Pentium.
Neurons are slower than computer logic gates - but that's more than compensated
for by the enormous degree of connectivity and parallelism in an animal brain.
Overall, a common housefly probably has more available compute power than
a modern desktop PC.

| (...) I'm not knocking the fly, I'm saying that landing on the ceiling is a very difficult problem to solve by realtime calculated piloting (even using a desktop PC). But it needs very little calculation at all if the problem is almost entirely (...) (19 years ago, 29-Jun-05, to lugnet.robotics)

| While I think mindstorms needs to be computer-programmable out of the box (ie no corner cutting by making the PC interface a seperate acessory), I'm intrigued by the concept of fixed programs as a robotics challenge - for many kinds of robot, far (...)
