Cythbot, Pneumatic Guitar Hero

cythbot

Here’s yet another robot hoping to dominate the human race through the power of ROCK. Cythbot was built to demonstrate Cyth Systems machine vision systems. The device uses a camera to watch the Guitar Hero monitor and identify notes for button presses. The strum bar is then triggered after a delay. The notes are identified solely by pixel intensity since star power can cause them to change shape and color. All button presses are done using pneumatics. The whole system is self-contained and doesn’t require a separate computer for processing. Our favorite part is that the controller remains completely unmodified and the industrial light tree used to indicate notes. The team says that the pneumatics aren’t quite fast enough to hit 100%, unlike some humans. Video of the bot in action after the break. Continue reading “Cythbot, Pneumatic Guitar Hero” →

Simple Servo Bot Plans

oomlout has posted some interesting plans for a simple robot. It’s based around an Arduino and is a platform similar to the Parallax Boe-Bot. The Arduino sends PWM signals to continuos rotation servos that drive the two main wheels. All of the structural components are laser cut from acrylic with slots to hold standard hex nuts. It’s an interesting technique, but the design has a lot of potential for improvement. Right now it uses two different power supplies and a breadboard for simple connections. From the video below, you can see that the balance could be improved as well. Continue reading “Simple Servo Bot Plans” →

Here’s a video of a student submission to the 2008 NHK RoboCon competition. The robot, who vaguely looks like a giant lego minifig, is controlled via a suit. The robot mimics the moves of the wearer. We can’t help but have visions of the clown from F/X2.

Autonomous Cookie Monster

[DJ Sures], who built the autonomous Wall-E, is back with another creation. His new autonomous Cookie Monster is certainly an interesting build. He had the cookie monster plush toy already so the first step was to flay the blue beast and insert a skeleton. He used another robot for that. There are two servos for the wheels plus one for each arm and one for the neck. There’s a distance sensor in the mouth. He built a custom board for the PIC18F4685 microcontroller which is running the same 2D mapping code as his previous bot. Check out the video of it in action below.

Arduino RC Airplane

[Olivier] told us about this fantastic project where he built his own RC airplane. The airplane itself is nothing special, it is the controls that are worth paying attention to. He used an Arduino Diecemilla , some XBee transceivers, and a SparkFun Wee. The main site is a general overview, but there are links to more detailed breakdowns of how to build some of the parts. There are several videos of him flying it as well.

Design Robots To Hunt Humans

The Department of Defense wants you to design a pack of robots that would hunt humans. Or, as they put it, “search for and detect a non-cooperative human subject”. While the project brings to mind Terminators, there are also non-terrifying uses for these robots, including search and rescue missions. The robots should be about 100 kilograms or less, provide immediate feedback, and defer to a human operator in the event of a difficult decision. This project presents some interesting challenges for robot designers. They’ll need to consider several key issues, like robot cooperation and decision-making abilities. We knew it was only a matter of time before the DoD turned the Grand Challenge into Death Race.

Robot Fish CAD Models

November 2, 2008 by Eliot 4 Comments

[Bre] dug up this excellent robot fish prototype project. The PPF-O9 has three servos. One on the forward fins to control depth, one on the middle joint, and one final one drives the tail fin. The battery box is mounted to the underside. The control scheme is interesting: the right stick controls left/right and up/down while the left stick controls the frequency and amplitude of the motion. They say the robot is fairly stable, but swimming and turning can be slow. They’ve included CAD files for almost every component to help you with your own designs.
