I haven't been around for while due to multiple hard drive failures (doh!) Try losing your iTunes folder the night before a DJ gig!!! Anyways, most of my data has been recovered and reinstalled, with the exception of my IRbot firefighter project. It's not a complex program, but there was a lot of tweaking of values to get it to drive straight and round corners smoothly, which I would rather not duplicate. So, my question is... Is there a way do pull the program from the ATmega 328 chip back to the Arduino IDE???
I have a dynamixel AX-12+ that sometimes doesn't move where I tell it to. It will just stop and the CM-5's TXD button and the light on the dynamixel will light. This happens even in the demo examples. Please help! Is there a way to fix this problem? Have others had this problem?
Just recently I picked up on Craigslist a mini Monster Energy Drink fridge, and have decided to possibly focus my college senior project around it. Ultimately, I would like to create a robot to fetch my drinks and bring them back to the couch for me, but first, as my robotics experience is still minimal, I have decided to initially build a system that when activated, opens the door to the fridge for me. I feel like using an electric linear actuator for this would be my best bet, however I am unsure of the best way to set this up (such as how to connect the fridge and fridge door with the actuator). I would appreciate any ideas anyone has on this...or even if you think I'm somewhat on the right track...
i was trying to figure out the best drive system setup. as of now this is how i have planned. i will have 2 stationary shafts acting like front axle and back axle, then on each side of the axles i will have dual roller chain idler sprockets, one chain will go down to the tire, and another will go to the motor positioned in the middle of the bot, this said, that means the motors will have 2 sprockets on them, one to go to the rear axle sprocket and the other to the front, then the wheels will have their own drive system with a set of pillow block bearings, axle, and sprocket.
if you were keeping track, that's a total of 16 sprockets for the bots drive system!, i don't know where you get your sprockets... [Read More]
The Central Illinois Robotics Club was invited to demonstrate at the Illini Boy Scout Jamboree event on September 12th and I wanted to make something special for the scouts to play with. Based upon previous demonstrations our club has done in the past, I knew that a hands-on project would be very popular with visitors and I began brainstorming ideas and decided upon an accelerometer-controlled marble maze.
Accelerometers can be demonstrated in many exciting ways and kids will likely be drawn to a demo considering the similarity to popular applications such as the Nintendo Wii. The goal of this project was to create an exciting game visitors can play while learning about sensors, microcontrollers, and hobby robotics.
Check out the webpage below for a complete description of this project including pictures, useful links, videos, and the Basic Atom Pro code currently being used.
Registration is now open for the 2010 Central Illinois Robotics Bot Brawl. The competition will take place on March 6th at the LakeView Museum in Peoria, IL. This year we're hosting beetleweights too! Here's a list of all the events:

I have a MANOI AT01 robot that can play hockey, walk, and do the hula-hoop like nobody's business.
But, the knee servos really take the toll with these movements. They run burning hot compared tot he other servos, and actually melt the gears inside of them. Usually it is just the left knee that is the problem, but the right knee recently gave out.
I can tell when one of the servos is broken because it either squeals, or doesn't grip. In all my cases, it has always been teeth on the gears just melting/chipping off. The gears are plastic, there's no metal ones (to my knowledge). The servo is the "Kondo KRS-4024S HV ICS Servo Motor Red Version"
The video security giant www.supercircuits.com has an IP camera. It looks like it might be worth looking into. It appears to not have the inconvenient boards connected at an angle problem the TrendNet camera has. I tried to find anyone who has opened one up, but nothing so far. Edit, the part number is, ACM4000
My name is Charles Whitaker and I'm currently working on my 11th grade engineering project. For this I decided to create a Oceanic Sunfish (Mola mola) type blimp:
I finally have some time again, so I'm going to start building Bioloid boards again.
If anyone has any requests for any new board ideas, please post them here.
One new board I'm thinking about is an AX/RX bridge. That will allow you to drive a mix of AX-12 and RX-series servos from an AX bus. This board will allow you to drive the bus from either direction (RX master or AX master), and will allow you to power the "other" bus separately.
Hello everybody,
My friends and I have been working on Vulcan 5, a fire fighting robot, and I thought I would post here and let everyone see our progress. We are eventually going to be taking it to the trinity college home robot fire fighting competition. A few weeks ago fergy started talking about going to the Canadian national robot games, and we were like that sounds like a good idea. Then we were like oh yeah we should take a robot. Oh yeah did I mention that we just started working on it? So all of the stuff that we were going to do over the last couple of months we now have to finish in 5 or so days. Fun stuff.
Anyway here a few stats on V5
controller: Arbotix
body: lexan, and aluminum
motors: 2x lynxmotion 7.2v gear motors with encoder shafts
wheels: 2-7/8" x .8" with hex hubs
battery: 7.2 volt Nimh tenergy
sensors: 3x sharp IR range sensors, UVtron, photoreflective sensor
fan: there is a fan on... [Read More]
I have 9x AX-12+ that I would like to sell. 2 of them are new in box and would like to sell them at $40 or best offer. The other 7 are like new and only have been played with for a little bit of time. Little to no wear on the motors. Will also include all hardware and cable. Would like to sell these for $35 or best offer. If you would like to buy all 9, I will sell them for $300 + $10 for S/H. Paypal is the preferred method of payment. Send me a pm or leave a reply.
Update: Just have the 7 like-new AX-12+ left. Come on guys, make me some offers. I would love for somebody to find a use for them instead of them laying in a box!
I know several of you are interested in building an autonomous or semi-autonomous Mech for the upcoming RoboGames in April.
I am starting this thread to have a place for discussions about challenges/ideas/solutions in and around the problem of how to build an autonomous robot that can compete.
I do not have a name yet but plan to enter a fully autonomous biped mech using a Lynxmotion BRAT.
Here is a youtube link to a Lynxmotion Rover that I put a CMUcam2+ head on that does color tracking. That work is the basis for the auto targeting system that I am developing for the competition.
Hello! Someone suggested I post this on the forums in case anyone else had the same questions.
I would like to control some AX-12 servos using a Parallax Propeller based microcontroller.
There is code a "Object" here (thanks to Mike Gebhard and Henk K for that), but now I am stuck on how to breadboard the circuit to make it work.
I still suck at reading circuit diagrams. I only made it through the BasicStamp 2 :"What is a microcontroller?" book because it had drawings of what the circuits should look like on a breadboard.
So I was wondering if anyone had a digi-pic of an ax-12 controlling circuit on a breadboard that they could share. Or maybe just a drawing. Or just helpful explanation of the logic of the circuit itself with parts labelled for dummies. ... [Read More]
