"@Thomas, I see no level shifting on the DOUT of the Adafruit adapter, which is Bill's concern. I did not check the Parallax one."

"I made an Autonomous Ground Vehicle with an Arduino. Much like the ardupilot setup, i could easily do it with an ardupilot if I had one."

"I would add some distance sensors (like IR or sonar) for obstacle avoidance or try IR sensors on one side for automous parking"

Motor, ESC, and Servos for sale

I have a Turnigy brushless in runner motor plus prop, 2 Hitec HS-81 servos, and 1 Hobby king 40-50amp ESC for sale. All in working condition, sold as is. The ESC has some extensions i soldered on and the female plug is not on it, just a…See More

DaveyWaveyBunsenBurner replied to Patrick Mccabe's discussion ESC says dont use above 3500mah battery
"The only thing I can possibly think of is if the ESC is really, really, close on specification. "it can take x amps for 15 or so mins, then starts to warm up rapidly"I suppose then you might hit some kind of theoretical capacity limit.…"

"Hi Patrick, not sure, if you are still waiting for an answer, but here i go anyway :) you are correct in your assumption that this limit is non-sense. the ESC only cares about volts and amperes, not about the capacity of the power…"

James Cann replied to Patrick Mccabe's discussion ESC says dont use above 3500mah battery
"Hi Patrick The answer you are looking for is this: If you try to use a battery that has a higher *voltage* than specified, you may/will eventually destroy the ESC. At all times, you have to stay below the maximum Amps or things will also overheat…"

Krzysztof Bosak replied to Patrick Mccabe's discussion ESC says dont use above 3500mah battery
"This sounds like typically chinese warning. One chinese smartass copied EU/US produced ESC rated 35amps that can handle officially 40amps for 30s, and so claimed his copy can handle 45. Because of a few mistakes and 0.1USD cheaper parts it handles…"

ESC says dont use above 3500mah battery

My ESC on the AGV says do not use a battery above 3500mah (something like that maybe a bit greater. I peeled the sticker off already)  with it. (there was a little sticker under the battery that said this, i took it off a while ago). Well this limits my driving time, and i would like more. So i am wondering why would there be a limit like this on it? i thought current was asked for, why would there be a limit for how much could be supplied? I want to wire my batteries in parallel to get longer…See More

"Patrick, "i dont get why most rc receivers have a small voltage rating that are lower than the batteries have." That is historical / backwards compatibility. Way back when rocks were new and I was roughly your age, R/C gear came with a…"

James Pearson replied to Patrick Mccabe's discussion RC receiver
"Just going to thrown in another solution I was considering encase my ESC did not put out a safe 5-6 volts. Its also possible to use a 7805 voltage regulator. Or maybe there is a problem with doing this... Any one feel to point out a problem with…"

AGV Chassis change

Yup, it now has 2 platforms instead of that plastic truck shell.

Here is a picture to remind you what it looked like…


AGV improvements

Posted on July 22, 2010 at 5:12pm 4 Comments

The AGV code has been improved tons with lots of help from Bill porter, Thanks Bill. A lot of cleaning up and basic improvements were done but so were major ones. Added PD control instead of the plain P like before. The code runs faster at 10hz. The best part by far is the added functionality of storing waypoints in EEPROM and using the Ardupilot config tool to upload the points. Just today i ended up…

My New AGV

You might remember the old one, which was just a prototype, this one is much better.

The new really big difference is the vehicle (you can see the name of it on the truck every where). I am pleased with…
