The U.S. Navy is developing Autonomous Swarm Robot Boats. These boats are outfitted with Control Architecture for Robotic Agent Command and Sensing (CARACaS), this technology was developed by NASA for the Mars rover. “Navy researchers installed the system on regular 7-foot and 11-foot boats and put them through a series of exercises designed to test behaviors such as escort and swarming attack. The boats escorted a manned Navy ship
At a glance this Robo Dog by M.C. Langer looks like something you might find in the toy section of your local department store. Check out the parts below that went into the building of it. “I used the following materials (probably you can easily find better materials and substitutes): 1 broken mouse (it doesn’t matter where you are; you can always find a broken mouse. Or you can “accidentally”
Dave from the EEVBlog got his hands on some junk electronic that is from the typical White Van Scam. Dave got this gear from the garbage room in his building. Some other tenant obviously got scammed and just tossed it out. Rule of thumb is not to buy your high end audio and video gear from the back of a van in a parking lot. In the video we can
This Acoustic Impulse Marker project by Adam Wrobel and Michael Grisanti of Cornell University uses 3 microphones to listen for sharp sounds, when a sound is detected the arrival time of the sound to each of the 3 microphones is used to determine where the sound came from. The project uses a ATmega 1284p microcontroller to process the microphone input but analog stages are used to convert a fast
This video by designboom gives us a glimpse into the making of an Arduino PCB. Arduino boards are still produced in Italy! You can see an interesting picture (last one at the bottom) which shows an arduino in a programming and test fixture. I am quite surprised to see that they are programmed individually, I would have though there might have been either a large program and test system
This is a cool plot clock made by Francisco Ramos Muñoz. It uses 3 mini servo motors, one to move the draw/erase mechanism up and down and two to move the print location. The lines are nice and straight so we can tell that some kinematic techniques have been employed here. The system is being controlled using an Arduino microcontroller and is sure entertaining to watch. If you are
Check out this crazy internal baffle structure of this cool Fostex FE206En Back-Loaded Horn Loudspeaker. Â “The back-loaded or rear-loaded horn loudspeaker system is like bass-reflex and double bass-reflex speaker types in that the sound radiated from the back of speaker transducer is utilized to enhance the bass response. The difference however is that back-loaded horn (BLH) speaker enclosures make among the most efficient use of the back wave from
