Hi Guys, Thanks for the heads up on the voice coils.. I checked my PWM frequency and it was running at 19khz. my problem was I was running waaayyy to much...
i need cheap solution, i m designing a robotics trainer kit and it needs 1. Motor Controller (PWM,PID based) 2. AT80C51 hardware trainer Kit 3. Universal...
Visited Robothon on Saturday- very cool event! Unfortunately I missed the RoboMagellan competition. Would love to hear stories on this event. Nice to see the...
Hello, I was hoping to purchase one of the robot kits (http://www.seattlerobotics.org/WorkshopRobot/kits.php), and it says they'll be available to purchase on...
Hi. The purchasing page should be back tomorrow (Tue 10-3). Those of us who handle fulfilling orders were busy with Robothon for the past several weeks, and...
I couldn't make it on Saturday this year. So didn't get pictures from anything that happened that day.. But got a few good ones from Sunday's Line Maze...
Thanks, nice pictures from the line maze event. Unfortunately none of my robot. It is probably because I had one of the earlier runs. Does anyone have any...
Yeah, there is one with it in the background. It wasn't that yours was an earlier run.. But running in 16 seconds and only running twice. I didn't have time...
Kevin, That was a great video. 'Just out of curiosity, does anyone know just who won what in Sunday's raffle? Tom C. [Non-text portions of this message have...

Hi Gus, ... I think I have video clips of all (or most) of the Line Maze runs. I've also got all of the Robo-Magellan stuff. I'll make a post when I get it all...
Thank you Dave, I'm looking forward to seeing the video clips. Richard, thanks for the offer to crop the the photo with Alegomazer in the background but don't...
We don't record that, just give the stuff to the person holding the winning ticket. I still have to ship some items to folks that weren't there, but off the...
Hi Gus, ... The video clips are up: http://www.davehylands.com/Robotics/Line-Maze-2006/ -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/...
That's Tom Saxton's robot, Twisty's Sister (since my first maze bot was Twisty). The board on the ARC board is the Expansion Board Kit. It's got some neat...
... I have sample code (n C) that exercises everything but the sound portion. I've also created an LCD library that has the notion of a HAL layer, so that the...
If you missed Robothon, or want to see if you made the TV, TJ Williamson is airing the footage he made on Saturday night. Kevin ... From: TJ Williamson...
Hi everyone, On my ARC 1 board, I have 4 servos, and I send these servos commands via serial port. My problem is that the 4th servo is a digital servo while...
I forgot who was the VEX coordinator for the Seattle area. I have a guy here in Orlando who is becoming a partner for FIRST VEX. I would like to connect you...
Do you have a snippet of the code you are using to setup the analog servo? A typical analog servo gets it's signal in pulses. A pulse happens every 20 ...
A "digital" servo will work with exactly the same pulses as an analog one. It may _allow_ faster pulse rates, and internally it may have motor PWM at much...
Hi, I have a question about PID loops and how to pick the frequency with which they should run. I'm planning on using a PID loop to control the SRS Workshop...
Unless you are going to use the time between ticks as your velocity, the limiting factor will be your velocity change. I.e. if your PID loop rate is the same...
This device reponds to verbal commands e.g get me a cup of coffee, make my bed, clean the libving room etc. It must first be trained this is accom plished by a...
Hello all: This series of threads on Voice Coil is nice. Now that this is a subject I probably need to raise my own "design" issues. Q1: Where can I get those...
