corobot_Upgrade_3Pretty Hate Machine’s offensive saws stalled while chewing on Ziggy’s metal armor. Being standard (hand-pull) gas-powered weed eater motors, they could not be restarted during the match. Jon Ridder’s Ziggy was fortunate not to have turned off.TIP: Other bots also lost controls in the ring. If your bot doesn’t restart its own functions, then put those features onto RC control. (Personally, I’d like more bots to use proprioception. That is, where the robot senses what’s happening to itself.)

Beside building Pretty Hate Machine, Christian Carlberg does special effects for movies. He says now that his greatest special effect will be to really impress the crowd.Christian did more than that. He earned the admiration of the veterans. His team was the only one applauded by other competitors as they returned to the pit carrying their wounded walker.

TIP: Walkers have an inherent advantage over wheeled bots because they move up and down: If your wheeled chassis is too low to the ground, your belly might get stuck on debris and you’ll be pancaked – immobile, spinning your wheels. Then there’s the stench of burning electrical motors.

Pretty Hate Machine Resting in the Pit. Saws are covered with black tape.
TIP: Choose your foot padding well. Christian used racquetballs for pads, and these were easily chewed up during the match. While that didn’t immobilize the bot, it gave points for damage.

A side note by Cristian Carlberg:”…after that first match I learned that you should let your
gas engine warm up for awhile. After that match I never had stalling problems, but I did have belt problems…”
