Coilosapien: Rail Gun On Yer Robot


It’s been a while since we’ve seen anything new on the robosapien front, but I’d say that a laser sighted rail gun for our favorite robots is worthy. From the video, it appears to have decent accuracy and a fair sized clip. It’s creator, [Marcus] says that he’ll have a tutorial up soon. Thanks to [Robert] for the tip. (Update: The tip says it’s a mini rail gun, so I’m not sure if it’s a rail gun or a coil gun.)

Self Parking Lego Mindstorms


[Korvost]
er, [Hybrid] sent along this video of a lego mindstorm self parking car. I don’t think I’d want it parking next to my ride considering how much damage it did to the blocks. Man, I need to upgrade my legos. Sadly, this video just re-iterates one of the my problems with Youtube videos. Video posters tend to fail to provide links with more information about their projects/hacks. Via [techblog]
Update: [ralphn] found the car. It uses an ultrasonic sensor to find a space big enough to park in – when it does, it automatically parks.

Don’t forget, Prizes and glory await the winner of the Design Challenge. Just 12 days left to get em in.

Just a quick bonus hack: The giant altoids tin battery pack w/voltmeter. [Via Make]

Line Following Roomba

line following roomba

[Ben Miller] came up with a really simple way to turn a Roomba into a line following robot. The Roomba already has four “cliff sensors” built into it. Ben just added a potentiometer to the two outside sensors and then tuned the pots so that the Roomba could detect black tape on the ground. It isn’t your standard line follower, but if you draw a path using two strips of tape the Roomba will gladly stay inside. Here’s a CoralCDN link to the video.

ROV Capable Of Diving To 400 Feet

rov

My buddy Willy Volk at Divester has always been good about passing along stories about cool remote operated vehicles and this is no exception. A team of 8 engineering students at RIT have built an ROV capable of diving to 400 feet. Most schools design there ROVs for competition in pools, but the RIT seniors had a real-world goal: exploring shipwrecks in Lake Ontario. They built a lightweight aluminum frame and mounted batteries onboard. The ROV moves via four commercial thrusters controlled by an ATMega128. There are 3 video cameras plus HID lights. All control comes from a laptop using an RS-232 tether. More details are provided in their conference paper PDF.

Roomba Midi Interface

todbot has developed a MIDI interface for the Roomba. RoombaMidi is an OSX application that acts as a virtual MIDI interface. It can be used by any standard MIDI sequencer and supports up to a 16 vacuum orchestra. It can even turn the vacuum motor on and off for a bass drum effect. I guess the circuit benders have a brand new toy on there hands, but who will be the first great Roomba artist?
