That little walker is quite an elegant solution. So few parts, so simple. My version users another motor as a counter balance (replace the "eye" with a geared moter). If I had more cams, I'd make this into a "caterpillar". Altavista's babelfish (...) (24 years ago, 10-Feb-01, to lugnet.robotics)

Not quite that simple, but you could arrange a touch sensor to be actuated by a small cylinder. Use a number of rubber bands to hold the cylinder "in" or ""down" to equal the force corresponding to the pressure you want in the tank. Put air from the (...)
