Meet GåågleBot. GåågleBot is a modified roomba that will not only vacuum your home, but collect data while it does it. While it is carrying out its normal duties as a floor cleaner, it will take pictures, collecting and analyzing all the data for later searches. With built in OCR, you can actually search for things using text strings.

Aside from just carrying out its normal job, you can also remote control it via the web. You can even control theirs!

Biped Walks With Eight Servos

This tiny biped shows a lot of coordination in its movements. As you can see, eight servo motors account for the locomotion with an ATmega8 as the brains of the operation. Posts for the first and second generation of this little guy feature several videos. We gather that a spreadsheet is being used to tweak the preprogrammed movement sequences. Trial and error, that’s how humans learned to walk, right?

RoboThespian: Chuck E. Cheese Entertainment Comes Home

February 25, 2010 by Mike Szczys 9 Comments

Remember your eighth birthday party when the animatronic band at Chuck E. Cheese sang happy birthday just for you? Now you can enjoy this any day of the year with RoboThespian. The complete animatronic platform has been modeled in Blender 3D. Animating the robot is as easy as producing an animation from its digital model. Lip syncing is generated automatically, with the handles to the right of the model’s head controlling facial expression.

Using Blender as a choreography tools is brilliant. We’re hoping someone will incorporate this technique in their Halloween shows this year.

Building The Yellow Submarine

February 23, 2010 by Mike Szczys 19 Comments

Submarine builds are always fun but frequently produce headaches when it comes to keeping the water out. [Jason Rollette] built this ROV to explore a shipwreck in Lake Michigan. The main structure is PVC and various bilge pumps are used for propulsion. An AVR ATmega32 controls the on board electronics with an Ethernet tether to the surface. He’s even got a visual basic program that displays system information and a video feed. It may not be as stylish as the last submarine we saw but it’s amazingly well thought out and well built.

Robocup Bot Places Wheels Perpendicularly

February 21, 2010 by Mike Szczys 17 Comments

[Eric] built this robot for the 2009 Robocup Jr. competition. The game ball has IR LEDs inside of it and this little bot uses eight IR detectors for tracking. Four motors mounted perpendicular to each other provide locomotion. Since this would normally have you traveling in circles, he used some omnidirectional wheels walled Transwheels. As you can see, they have small rollers built-in and allow movement in any direction if the motors work together. A couple of L298 controller chips handle the motors. [Eric] wrote a program to calculate the PWM necessary to drive the controllers and to coordinate movement of the wheels.

Don’t miss the demo videos after the break and, if you’re not a fan of wheels, stop by and see the bi-pedal soccer robots. Continue reading “Robocup Bot Places Wheels Perpendicularly” →

Drink Making Unit

3 breast pumps, a Meggy jr RGB (slightly modified) and copious amounts of alcohol. This sounds like a typical weekend at HAD headquarters, but it is in fact the parts list for the Drink Making Unit by Evil Mad Scientist Laboratories. Created for the upcoming Barbot 2010 event, this unit is a cocktail mixer. Load 3 liquids in, program the Meggy and you can push a button to dispense. We are pleased to see how much they modified off the shelf components to make this happen. Yes, there could be major improvements like mixing, more liquid reservoirs, and a better cooling system, but we think this thing is pretty slick.

Hexacopter

Quad copters have been pretty popular for the last few years, but this one is new to us. Take the same basic layout, but bump it to 6 rotors. Then you’ll have the hexacopter (google translated). With 6 rotors, built in GPS and stabilization and a camera mounted on the bottom, this thing is pretty well equipped. You can see how agile and stable it is in the video above. We know it isn’t necessarily new, but it is new to us. Of course, you don’t have to stop at 6 rotors. You could always just continue on to 8.
