Design of a UGV for rough terrain

I am an absolute beginner in building bots.

I want to build this vehicle( electric one) for irregular terrain.

size is 2m length 1m height and 1m width.

should be able to climb ditches .5m in height(vertical)

and also carry some weight(200kg load)

I am through with the design selection part.

Arduino voltage regulator and other questions.

 Hello, I have a few questions I hope somebody or several people can answer :)


Common Electronics Knowledge Questions

Hi LMR. I have already made a robot, as you may know, but all I did (on the physical/electrical side of things) was plug a few cables into the pre-made servo ports on the Board of Education, as my copy of Electronics for Dummies told me to do. I read the entire thing, but they explained a few things in a way I didn't understand. Like the names for stuff, and what each means. Until now, I thought voltage was a measure of battery capacity. I FAIL, I know. I've sorted it out, so now I know about amps and volts, but I have a couple technical questions regarding electricity.

Tank chassie, pull apart


Just brought this tank, so just wanna hear if any1 have tried to pull it apart. As to begin with i only need the bottom of it, the tracks and the engiers.

It is a RC tank, and is about 80cm long. And the cannon can fire BB bullets.


 'Hope that there is some one out there, that can help me. Thanks.



Quick Feedback on a Theory?

So, for fun, I found this website where you could "create" your own AI, Pandorabots.com: which worked with AIML. On this website, they give you a list of keywords your AI reacts to in the AIML file that they provide for you. (Since you have the option to use Alice or the Elvis bot as a base, the list is pretty large.)

PSP Screen Pinouts.

Edit: Learned what I needed to from previous question, didn't wanna create a new forum for every Question I had (we'd be at node 20,000 in no time).


Give a soldier a hand?

I have a problem and I hope someone here has a solution. Here's a little background on me to set the scene. I am a U.S. Army Explosive Ordnance Disposal Technician (the guys in the big green bomb suits that take IED's apart). I am not the most electronically sound guy in the world and robots? HA HA HA!!! I can drive the tracks off our Talon, but I don't even try to get into how it works. Just a big expensive remote control bomb-killing car for me. Here is my issue. It may sound trivial to some of you, but to me it's mind boggling.


hello all, this is my first post on this website so i hope i don't sound to much like a noob.

Need help to build a obstucle avoiding robo using GH 311RT sensors

i am having this ultrasonic  sensor



Anybody please tell me how to interface this sensor with arduino, i planning to create a obstacle avoiding robot using two dc motors and a servo with this sensor.

Please help me with programming and circuit...
