Mindstorm Plays Tetris For You

Obviously you’ve got too much hacking to do right now, but that game of Tetris isn’t going to play itself. [Branislav Kisacanin] has you covered with his Tetris-playing robot which is build with LEGO Mindstorm pieces. The setup is actually pretty complicated. A Texas Instruments DM6437 video development board watches the computer screen via a webcam and calculates the next move. It then outputs that to a grid of LEDs which the Mindstorm watches using a light sensor. See it in action after the break and then take some time to check out our other various Tetris based hacks.

Stanford’s Stickybot3

[youtube=http://www.youtube.com/watch?v=0y2MVuSyQlg]

Stickybot has gone through a pretty radical upgrade.  You may recall the gecko looking glass walking bot from all over the net. While it was pretty cool, the technology has gone much further. Not only is it designed to look like a gecko, the feet are actually made to adhere to surfaces in the same manner. They are using an adhesive system based off Van Der Waals forces.  Though the stickybot 3 doesn’t walk yet,  the feet are already impressive. Look how little of the foot is actually making contact with the glass. See how easily he can remove and re-adhere it? Simply amazing.

Robotic Chess Opponent

[Dennis] is using a robotic arm as a chess opponent. Rather than using an under-board movement system, a Lynxmotion AL5A robotic arm plucks each piece and moves it to the next space. He tells us that he’s using a Python script that he created to process the moves and decide what’s next. That must mean he’s using a webcam to capture the location of the pieces on the board. About half way through you can see the robot run into one of the pawns. We’d like to know if he has problems with picking up the pieces as the game progresses and they get further away from the center of each square. From what we can see, looks like a great job!

Giant Robotic Giraffe Getting A Giant Robotic Facelift

If you’ve had the opportunity to attend the annual Bay Area Maker Faire, you’ve likely encountered Russell the Electric Giraffe. Modeled after a small Tamiya walking toy scaled up to the height of an actual giraffe, Russell was created by [Lindsay Lawlor] in 2005 originally as an “art car” providing a better vantage point from which to enjoy the Burning Man arts festival. In the intervening five years, the Electric Giraffe has enjoyed face time in dozens of parades, trade shows, magazines and television appearances.

Scattered about [Lawlor’s] living room floor at the moment are the giraffe’s dismantled steel skull and several massive Torxis servos (the red boxes in the photo above) — Russell is being upgraded. One of [Lawlor’s] goals in returning to Maker Faire each year is that he not simply present the same exhibit time and time again; the robot is continually evolving. Initially it was little more than a framework and drivetrain, and had to be steered by bodily shoving the entire 1,700 pound beast. Improvements to the steering and power train followed, along with a “skin” of hundreds of addressable LEDs, cosmetic improvements such as a new paint job, and technological upgrades like interactivity, radio control and speech. His goal this year is to bring expressive animatronic movement to the giraffe’s head and jaw, hence the servos, push rods and custom-machined bits currently strewn through his living space-cum-laboratory.

The Trans-atlantic Battery Bunny Divide

This somewhat frightening armature is the base for the iconic energizer bunny. While we love seeing the guts of popular robotics, this brings up an interesting fact. In Europe, the bunny is the symbol for Duracell. There’s an interesting story where Duracell had used the bunny for years in europe, only to inspire Energizer to copy them stateside in 1989. This one will be available on ebay shortly.

Project J.A.R.V.I.S.

[brightcove vid=76029544001&exp3=16977198001&surl=http://c.brightcove.com/services&pubid=245991542&w=470&h=325]

Project J.A.R.V.I.S. is an attempt to create a digital life assistant, or DLA. The name comes from the version in the movie Iron Man. While the details of the build are pretty slim, you can see that he’s using a mac mini for the base with an Arduino controlled RFID reader at his door. What is really interesting is how functional he has actually made it. Watch the video on the site to see a pretty good explanation of features.
