Subject: [alt-beam] 4-motor walker


Hi beamers,

After finishing a solar-engine based robot and a two motor walker I'm
currently building a 4 motor walker.
By adding 2 tactile sensors in the front(left-front and right-front) of the
walker he should be able to make a turn when one sensors hits an object.
When the 2 sensors both hit an object the bot should go into reverse.

I have a few questions concerning the circuit that will be needed to achieve
these actions.

Should I hookup the motors to a 8-nv microcore (a loop) and drive the motors
with the 74hc245.
Can I use the 74HC240 for making the turns and for the reverse function.

It would be great if somebody could help me with these matters.

Thanking you in advance

B. Beulen
