Hobbyist One-Ups Sandia Labs
An anonymous reader writes "A robotics hobbyist has created what he claims is the world's smallest autonomous robot. The robot is half the volume of the robots produced by Sandia National Labs in 2001, moves quite a bit faster, and was made using techniques and supplies accessible to anyone." While Sandia Labs has had some time to improve on their original designs, it's still pretty cool to see what one can do at home as well.
Why not place it in a box? I understand he doesn't have the sensor working to stop it from going off the table, why would he not then place it in a box as it looks like the device recognizes an obstacle and changes courses.
I for one swat our new minute overlords with a flyswatter.
.. but colour me impressed when someone comes up with one which can handle stairs. And if anyone's thinking of mentioning Asimo, I present Exhibit A
I just can't imagine what people that take that claim as a challenge will call the next four microbots. Well, at least it keeps a simple naming scheme. :wq)
I'd like to see Emacs, the microbot, though... It makes toast, does taxes and raises your children, but unfortunately it has the size and weight of a phone book, draws a kilowatt of power and the wheels don't quite reach the ground.
(Disclaimer
In a fair world, refrigerators would make electricity.
It could be an alternative to pliers for the removal of that stick you got stuck up there...
Pshaw.
I wish that thing was bigger so I could turn it into something useful like a vacuum cleaner.

Think about it... a bright person allowed to:
- concentrate on a project all day long
- without PHB shaking deadlines in front of him
- without being burned out on meetings all day
- without the distraction of phone calls, personalities or politics
imagine what *you* could get done. I'm drawing a parallel to the busy workplace - not in any way do I mean to detract from this guys accomplishment. By all means, he's done something remarkable.

Kids really enjoy problem solving for things that move. This creates a great learning environment.
Even plain old bump-and-turn robots have some very interesting control problems, like getting trapped. THis really helps people extend their problem solving skills.
I also work in real-world robotics (big multi-ton mothers).Sure we use simulations for developing control ideas, but those are pretty limited. You can test out various theories, but simulation only takes you so far. You need the real thing to get the dynamcs correct. For some real fun you want to see a huge robot go out of control.
Some of the most interesting research in robotics is being done at the hobbiest level. Lejos http://lejos.sourceforge.net/ has some very interesting abstractions and models for defining and controlling behaviour. Then there's also http://www.seattlerobotics.org/
Engineering is the art of compromise.
You learn from your mistakes, and there's no substitute for "the real thing." You can crash the robot in a sim over and over, and it's no big deal. Real destruction with sparks and fire teaches you life-lessons ... I had a summer job (many years ago) with a rather large gub'ment contractor. We were working on a robotic arm tasked with de-palletizing ammunition - ammunition of the 5-inch diameter variety. The second day at the site, the programming team had gotten the arm all twisted up after several hours of fussing with the control software. The design lead saw the "home" switch on the control panel, and decided that starting from a clean setup would streamline things.
...
... which was thankfully de-energized.
*** CRASH ! ***
Nobody had programmed any obstructions within the cell, and some Genius had put the servo drive rack within the robots hemisphere of motion. The shortest path to the home location went directly through the servo drive rack. And when I say "directly through," I mean "ripped the rack in half." Literally. Big multi-ton mother, indeed.
So there's a bunch of down time while equipment is replaced, and we're back on-site after about 3 weeks. To my surprise, the servo control rack is still within the robot's operating envelope, but the obstructions have been properly programmed. There's even a short demo where they try to move the arm into the obstruction, but the machine refuses (rather politely, I might add.) Several days of progress are made before the Brain Trust is at it again. One of the programmers decides it will be "cool" if the robot commits suicide - he'd been reading an Asmiov book if I recall correctly. So they program the BMTM arm to reach over and press the main power switch on the servo control rack. It refuses. So they place a piece of 3/4" black pipe in the end effector to create the necessary tool offset. Attempt number two goes [click]
*** CRASH ! ***
They had shut the main power breaker off, resulting in a rather ungraceful de-energizing event. Apparently the servo drives can "lurch" if power is abruptly removed. The arm stuffed the black pipe and the end effector halfway through the servo control rack
Not surprisingly, we were not invited back for a third attempt to program the arm.
You never had a small child, specificall a boy.
1.5 remove the robot from the child nose or ear, say no sternly.
1.6 remove the robot from the child's ear or nose (whichever was the opposite of the first and say no again)
1.7 Now remove it from their mouth.
Boys like to shove crap up their nose and in their ears for some reason.
Do not look at laser with remaining good eye.
