 | | Chameleobot the Quadruped: 4 and 1/2 foot MOC
|
| Chameleobot the Quadruped is a Mindstorms creation that is a bit bigger than your average quadruped. It is 4 and 1/2 feet long and uses 2 RCX's, 6 motors, 4 touch sensors, a light sensor, and a host of gears among some of the things. Chameleobot is (...)

|
| (...) Thanks. Here's how it works: Consider only the right piston for a moment. The output of this subsystem (which will be driving the left piston) is simply (A&~C)|(~A&C), which is an XOR operator, or a half-adder. So what drives the left piston (...)

| (...) Very impressive! Two pistons! (...) Well, I can eliminate one switch on the Cin/A/NOT A piston. You don't need to throw the switches the full range do you? You can get the release from A/NOT A, and have to have it come from the local switches, (...) (21 years ago, 28-Jun-03, to lugnet.technic, lugnet.robotics)

| Okay, Kevin... you talked me into trying this inverted logic thingamy. (I'm just too competitive for my own good...) How's this? (URL) A and NOT A, B and NOT B, and Carry in as inputs and produces A+B+C, NOT A+B+C, and Carry Out as outputs. I saw no (...) (21 years ago, 28-Jun-03, to lugnet.technic, lugnet.robotics)

You have an extremely good point there. I already have a LUGNET (...) (21 years ago, 28-Jun-03, to lugnet.technic, lugnet.inst)

| (...) Ahh... you are stuck in single pressure line mindset. The modern LEGO pneumatic pistons are dual ported where pressure into the port at the base makes it expand, and pressure into the port at the top makes it contract (presuming of course that (...)
