First time here, hello guys, i'm a student in mobile robotics, but i'm not familiar with c++, is there anyone can help me doing a code of path following or point to point ? please? thnx

A while ago I posted a more polished project description of this robot along with some better pictures on the EEV Blog Forum, as a way to bring the project to a close. I linked back to this thread as the build log, but I guess I forgot to post a link here to the write up on the EEV Forum, so here it is: http://www.eevblog.com/forum/projects/1970's-robot/

They have 5 types of wheels with 4 grade for each. You can see their website for more detail
Depends on your robot, smaller rollers can help the robot to move more easily and more important is that in robocup competitions that the size of the robot and the mass is very important these thin and light omni wheels can help well
does anyone know more?

I'm new here, and I'm new to robotics. Before the question a little background on me - I run a design studio in London, I have a physics and programming background, and my first career was as a 3D modeller for the visual effects industry. So I can handle code, and I can handle CAD (I use Rhino and Autodesk) but I'm very new robotics. I did a small stint with practical effects so understand servo control, and I also own a small 3 axis mill but am looking to upgrade to the PocketNC.
Quite frankly I'm bored. My son is interested, and as I want him to learn computer science, robotics, and AI I want to help him as much as I can. I like Python as a basic language so I wondered if there was a way to communicate easily via Python to a controller that will let me hook in off the shelf sensors and servos, and get data back? I like to idea of being able to do basics, but also handle complex calculations on the host computer.
I've read up on all the search results you get for Python and Robotics, but I'd love to hear form anyone who has it working rather than reading sales material.

Carbon fiber and fiberglass will both work just as well for your project. You're not going to be shooting a missle at this thing or hitting a barrier. Carbon fiber clearly much tougher than fiberglass but either would work. I've laid up both and thin carbon fiber lays up just like fiberglass. Previous commentor is right, it is more expensive so most hobbyists tend to use smaller bits of it but it's readily available on ebay and amazon in various weights.
The trick with getting good carbon fiber results is to use a really good epoxy resin
I reccomend you buy C&J Epoxy resin.. the gold standard of epoxy resin to lay up fibgerglass and carbon fiber. Dries glass clear. Worth the money. You can even sandwich layers of fiberglass and carbon fiber or if you want to get really serious you can even do carbon fiber and kevlar. But if I were you'd i'd lay it up in laybers of fiberglass and some carbon to get the stiffness you want and thickness.
anyway those are my 2cents

Looking at the cover of your book that looks like they came off of a big wheel.. you know those electric cars they buy for the kids. You can find those at garage sales and goodwill stores from time to time. They make horrible tires for robots because slippage on hard plastic wheels means you can't use encoders on the wheels. You really need something with good rubber which is why i suggest the contact wheels. Failing that I'd go for some kind of penumatic wheel (something like a real tire.. maybe handtruck wheels, wheel barrow wheels, or garden cart wheels. You can find run flat rubber tires in the dimensions you're looking for 10-14" if I recall. Might be worth a look?
