Hi guys, I looking for some feedback from anyone who has used modified servos (continuous 360deg operation) as the base for a wheeled robot. I considered...
I have used these on beginner mini-sumo robots with much success. So far I have never replaced one, and the robot was built about 3 or 4 years ago. They...
I used them in some of my ant weight bots( 1#). worked great. Gotta be careful though not all servos can be hacked because some have only patially cut gears...
Chris Parker mentioned: Tuesday, July 31, 2007 11:23 PM ... Looks like they have bipolar outputs, is that right? Any idea on top end frequency response? I...
Neither could I. However, I noticed a small typo in the code I sent yesterday. Actually, it was not so much a typo as an inconsistency between my comments...
Thanks for the code, that's exactly what I need to see. It may not come into play in this competition, but the lab has plenty of applications for PWM driving. ...
I have used them on several 'bots. As others have said, they aren't fast, but they work well enough. Parallax sells pre-modified servos. I like them because...
... Hey Randy, go to digikey.com and enter in the p/n. They have the spec online, but don't stock the parts, even though they're listed in the catalog. I got...

... I can attest to the TSD working very well, too! I had a wheel jam on my robot and the bridge shut itself down nicely, and after about 20 seconds of...
Excellent feedback/info ... agreed that it should be better with dual bearings ... interesting though that the next servo up (HS-475) uses Karbonite gears but...
I am planning to model it off the Octobot: http://www.robotstore.com/store/product.asp?pid=419&catid=1549 It will be running around for sometime ... Eventually...
Thanks for the hint ... the tacho idea is good ... Do you find the difference between the two servos can be taken up just with an offset or does it vary with...
The problem with this approach is that the center point will change with battery voltage. A better solution would be to use encoders on the wheels like these:...
I run the servos on regulated power, so that never changes. I have need for good dead reckoning with this 'bot, so the reduced speed is worth the consistency....
Hi guys i am trying to control a dc motor using pic and a ic driver for the motor.Do you guys have any suggestion what type of ic driver can be used to control...
Both ways are valid ... a regulated supply may eat some battery power on the higher motor currents than just having cpu/logic circuitry regulated ... but then...
Hi again everyone! Been busy as usual tinkering away on the mini-sumo- I just finished the front line array (for detection and line follow) and rear edge...

... Thanks Randy, sometimes you just need someone to say it! I've done the same thing in the past with my discrete H designs but it just didn't make it into my...
I'm going to try and use this motor driver IC in my CD bot. It's not the most hobby friendly of packages. But I'm willing to go through hoops that others may...
Thanks Richard! I dunno how I missed that one. Guess I'll order up a few to try out- many pins tho, but the small package is pretty good selling point for this...
Well the min voltage on that driver is 8V I believe for the motor power, would have to check the data sheet again. I'm going to be running it on 11.1 (3 3.7V...
Yeah I just browsed thru the sheet, it is not going to be suitable for my app.- although i could get away with the minimum V rating the current would get me....
Hello Everyone, I have a problem. I need to connect a serial port over IP via ethernet and then back to a serial port. I know there are programs that will do...
