Dart Board That Automatically Moves So You Score A Bullseye Every Time

March 21, 2017

This is a video demonstration of the dart board built by former NASA engineer Mark Roper that calculates the trajectory of your throw, then quickly moves the board so you score a bullseye with every shot. Oh yeah? *closes eyes, throws dart into opponent's chest* Must be broken.

[Mark] spent three years designing, building, and perfecting this dart board, which relies on six Vicon motion-tracking cameras and standard darts upgraded with simple infrared reflectors. It takes just 200 milliseconds for the computers powering the dartboard to predict the trajectory of a thrown dart, and an additional 200 milliseconds for the dart board's six stepper motors to move it into position. Before impact the system is able to refine its trajectory tracking and reposition the board as many as 100 times to ensure the dart hits the bullseye.

This reminds me of the time I was playing darts in college (at the London Underground Pub at Virginia Tech) and another player was sitting next to me on a tall bar stool waiting his turn and accidentally dropped a dart towards his lap and instinctively snapped his legs closed to catch it and jammed the entire tip straight into his femoral artery. The initial blood squirt hit the ceiling, I shit you not. Are you getting queasy? I'm getting queasy.

Hit the jump for the video.

Thanks to Marty, who challenged me to a game of 501, double in, double out, for a pitcher of beer. You're on, buddy!

    Interesting idea, very stupid image used for the article.

  • GeneralDisorder

    I bet I could still miss.

  • You buried the lead with that femoral artery puncture story, GW. Is that a real thing? Because that's pretty fucked.

  • Geekologie

    yes i bet the blood is still there unless they replaced the ceiling tiles

  • You have lived, my friend.

    Now they just need to do this for toilets and urinals so that the pee will always go in and moms everywhere will rejoice and call this dude a hero. LOL

    Toilets that relocate in .2 seconds? A NASA style vacuum pee hose might be more practical.

  • Jenness

    You really think a sucking hose won't get used improperly in a typical household with growing boys and men? I just see some people using it right and other people not cleaning it, getting their freak on and then getting infections because guys tend to not think things through when they are in the throes of inspiration.

    I would take that as a personal challenge.

  • The Magnificent Newtboy

    Fight the power! Try and catch my urine on the ceiling!

    I think it's pretty cool, definitely amusing, but I don't understand why those people are celebrating hitting a bull's eye like it was through any skill of their own. Maybe it's just me.

  • Brock

    Maybe someone should tell them that the bullseye is not the highest scoring spot...

  • sebastian

    correct, but it does have the smallest surface area so it is technically the hardest spot to hit, and therefore the spot most worthy of joyous praise for hitting.

  • I think it's more like excitement when a magic trick works.

  • I like it when super duper smart people play in silly ways.

    Humans are awesome. :-)
