Let's Make Robots!

Researching three-wheeled off-road robots, asking for info.

Hello everyone,

I've been thinking about building a large off-road robot for a while. I want to make it a fast three wheeler that uses two bicycle tires in the front (bmx size) and a smaller child's bike wheel on a caster in the rear. All of the wheels are going to be independently suspended, with leading arm suspensions in the front and a trailing arm in the back. One design goal is to make it faster than a person can run (roughly 10-15 mph).

Code Post - Interfacing Arduino and Python

This is something I've done by hand at least ten times and always seem to lose it so I've decided to post it here. It is an easy way to debug and test stuff will developing software for the Arduino (or any Microcontroller really). There is a python code that sends string messages to the arduino over serial based on which arrow key on your keyboard is pressed. There is also an Arduino code that listens for these messages, then repeats the message back to the PC to make sure it went through.

What quadcopter should I get for free!?

Guys,

I have a unique problem. There is some money at where I work that needs to be spent fast. I would like to spend it on a quadrotor but I haven't ever looked into buying one. There are tons of options but little time. Is there a quadrotor that any of you would recommend? I'd like to get a full kit with transmitter and everything. I could probably get away with spending $500 US. I don't really have a plan for what I'll do with it yet, its just the perfect opportunity for me to get one.

Thanks,

Aaron

Transmitting 2 HD-SDI video streams over wireless

Hello all, I've got a problem I've been scratching my head on for a couple days and figured I see if anyone here can help. 

Let me set the scene. 

You have two high definition camera's onboard a robot that have HD-SDI (or HDMI) outputs. 

You need to transmit these camera feeds to a laptop wirelessly to view. 

You have a small "mini-PC" computer on the robot (similar to one of these http://www.stealth.com/littlepc.htm). 

The best all-terrain robot I've ever scene

This was mentioned in a post awhile back (http://letsmakerobots.com/node/27879), but I thought it was awesome enough to post the video here.
