Hi All,
Ben Jackson's robot that avoids obstacles without a CPU got be to think about
the idea of using mechanics in place of AI.
As I understand Ben's bot, it's built with a diferential. When the robot
drives normally, the differential turns only the front wheel, moving the bot
forward. When the bot hits something the front wheel will jam, causing the
differential to drive the back wheels, which turns the bot based on how you
design the back wheel drive.
My first though is could a similar design be added to the bot so that when the
front wheel jams, the diferential drives a second, similar differential. The
second differential drives an arm that tries to push the obstacle out of the
way of the bot. If the obstacle is too heavy, the arm stalls, causing the
second differential to drive the rear wheels and move the bot, just as the
original design did.
Another thought would be using solar panals to build a light seeking bot. The
panals would be attached to a light sensor and whichever light sensor picked
up the greatest amount of light would power a motor to move the bot. There
would be two motors used to drive the bot. If both the left and right panels
detect the same amount of light, the bot moves forward by spinning both
motors. If one panal detects more light than the other, the opposite motor is
spun, turning the bot to the light. I know such a bot could be built with a
CPU, but I believe one could also be built without a CPU, and perhaps without
even using a logic gate.
If a collection of these "Dumb AI" methods were discovered, they could be used
in combination to create even more complex bots.
Here's that link to Ben's bot again:

A semi-rigid rear axle means that large turns cause stalls, which influences the robot (...) (25 years ago, 7-Feb-00, to lugnet.robotics)
