Tweenbots Rely On Human Help

tweenbots

[Kacie Kinzer] put together an interesting social experiment: Could a robot navigate purely by the help of strangers? She constructed an inexpensive Tweenbot robot that would drive in a straight line. A flag was attached to the top with a plea for help and a destination. Surprisingly, on the first run it was able to traverse through Washington Square Park in just 42 minutes with the help of 29 people. You can see a video of the first run below. This is part of [Kacie]’s thesis work at ITP and she has many other bots planned. While it’s a great demonstration of human kindness, there’s another lesson: If you don’t think your public project looks innocuous enough, draw a smiley face on it.

Stepper Motor Controller From Old Scanner

[Murray484] submitted his instructable on how to create a stepper motor controller from an old scanner. He removed the motor and controller from an old scanner then harvested the parts. He’s pretty much starting over, taking the ULN2003 chip from the scanner motor controller and putting it on a fresh board. He then wired it all up, installed the software and got it working. Finally, he built a container out of cardboard for it all. Though he could have made it nicer looking and used higher quality building materials, he was trying to make this a “green” project for the epilog laser cutter contest. He’s done a good job recycling, this could be pretty useful.

Jak, The Blackjack Robot

[Paul] sent in this Robotfest 2009 exhibition competition entry. This is Jak, the blackjack robot. This seems to be a convergence between a digital game of blackjack and a physical game. The robot scans each card as it deals them and feeds the data to a piece of software that tracks each players hand. The players select their next step on the screen and the robot responds appropriately. They have won 1st place in the Ontario competition and are now going to the international level. Jak wins a round in the video, but we didn’t see him celebrating. Come on guys, make him flash some lights or talk some trash.

Portal-ish Automated Turret

turret

[RazorConcepts] has built this cool automated turret. It is a home made frame with an airsoft gun, a Roboduino development board, a rangefinder, camera, and some servos. They programmed it to keep up constant random banter from the game as well as respond appropriately do different inputs. For example, it complains when you pick it up or knock it over as well as announcing if it has acquired a target. The range finder is mounted on its own servo which constantly sweeps back and forth, so the turret itself mainly sits still. You can see that the tracking is not so great in the video. [RazorConcepts] notes in the instructable that this is because the main focus was just to make it for “show”. We’ve seen our fair share of turrets before. We think he did a good job, but if it is just for show, maybe spend some more time on a nice body and smoother motion.

A-pod

We know it was just two days ago that we were ranting about the hexapods known as Phoenix, and their creator [Zenta]. In the comments on that post, [Bluehash] pointed us to [Zenta’s] latest creation. This is A-pod. The sheer articulation and believable motion here made this robot worthy of a post all it’s own. A-pod has a 2 dof “tail” and a 3 dof head with a total of 25 servos to drive it. The addition of the head adds so much character, add some face tracking and it would really blow us away. Well, after it fetched us a beer. He notes that he’s still working on the leg mechanicals, so it doesn’t do much walking yet.

We’ll file this one under “creepy yet amusing”. You can now order a MechRC robot with a 3d replica of your own head mounted to it. The site thatsmyface.com is offering this as a product. Simply take some pictures of your face upload them and mark some options. They’ll send you your robotic replica, ready to go. As they point out at botjunkie, they’ll put any face on there that you have some decent pictures of. That’s even creepier.

Bots 4 Tots Charity Launched

Bots 4 Tots

If you feel the same way that we do about robotics, you probably wish that you had more experience with them when you were a kid. [Don] felt that way too, and he decided to do something about it. So [Don] and his partner started the Chicago based organization Bots 4 Tots, with the mission of introducing inner city kids to robotics. [Don] told us that his organization plans on starting the kids with snap together projects like OWI’s Jungle Robot. After a few snap together projects, they plan to introduce the kids to soldering and hope to eventually move on to a larger collaborative project that all the kids can work on. Of course, doing all of these things requires money. Thats where we, as the DIY community, come in. So feel free to hit up the Bots 4 Tots site and make a donation to support their worthwhile cause, we know we will.
