LEGO fun



Comments:
  • 1-1 differential drive

  • 2 touch sensors used to count every half revolution for accurate movement and collision detection

  • motors driven via PWM to avoid damage during collisions since we are not using the clutch gear

  • tray and RCX2 is on a hinge, somewhat like a hatch back, for easy access to battry compartment

  • funny looking antenna thing is used to indicate the tray has been loaded. Light sensor repurposed as a touch sensor


Cheers,

500 member VIGILANTE POSSES with nuclear weapons....

"Yeah, but suppose the metaphor ran in the OTHER direction. Suppose the HIGHWAYS were like the NET. All right! Severe craziness. A highway HUNDREDS of lanes wide. Most with potholes. Privately operated bridges and overpasses. No highway patrol. A couple of rent-a-cops on bicycles with broken whistles. 500 member VIGILANTE POSSES with nuclear weapons. 237 ON RAMPS at every intersection. NO SIGNS. Wanna get to Ensenada? Holler out the window at a passing truck to ask directions. AD HOC traffic laws. Some lanes would VOTE to make use by a single-occupant- vehicle a CAPITAL OFFENSE on Monday through Friday between 7:00 and 9:00. Other lanes would just SHOOT you without a trial for talking on a car phone.

AOL would be a giant diesel-smoking BUS with hundreds of EBOLA victims and a TOILET spewing out on the road behind it. Throwing DEAD WOMBATS and rotten cabbage at the other cars most of which have been ASSEMBLED AT HOME from kits. Some are 2.5 horsepower LAWNMOWER ENGINES with a top speed of nine miles an hour. Others burn NITROGLYCERINE and IDLE at 120.

No license tags. World War II BOMBER NOSE ART instead. Terrifying paintings of huge teeth or VAMPIRE EAGLES. Bumper mounted MACHINE GUNS. Flip somebody the finger on this highway and get a WHITE PHOSPHORUS GRENADE up your tailpipe. Flatbed trucks with ANTI-AIRCRAFT MISSILE BATTERIES to shoot down the KRUD Traffic Watch helicopter. A little kid on a tricycle with a squirtgun filled with HYDROCHLORIC ACID. "
