We had a pretty successful first try at the PARTS Indoor Challenge: four entrants.
Event #1: all four competitors gave it a try:
  4th place: Brian with 23'4" short of the end
  3rd place: Marc with 19.7' short
  2nd place: Jeff with 11'5" short
  1st place: Pete with 5' short
Event #2: no one was ready for obstacle avoidance; skipped
Event #3: three competitors made attempts; no one really finished, 
  though Jeff was declared winner as his made it back near the start
  3rd place: Marc, DNF (did not finish)
  2nd place: Pete, 24' (hit a building support column)
  1st place: Jeff, 9'1" (did not round any corners)
  The course turned out to be too large for the space. Next time we may go for 
  a smaller square, maybe even in the meeting room.
Event #4: two robots made attempts, no one finished.
