CE Project: CE Bot

[joe3204]

if the bot is fitted with tracks (or something on those lines) won't it consume more power as compared to wheels? tracks will have more surface area in contact with the ground and hence friction will be more. how about using independently suspended wheels? they'll be more suitable for rough/uneven surfaces...

As for 802.11y. Its seems like a good choice until it comes to implementation which is very very new and what IC's? Programing it will be new?

And as Ash pointed, we will compile pros/cons soon, moreover, we shoild also get info on what modules are available in the market which impliment WLAN and compare them too.

Till then here is the wiki on 802.11a/b/g/n/y : IEEE 802.11 - Wikipedia, the free encyclopedia

EDIT:

I tried looking for some info on this, but mainly the wiki gives info on ranges. Power consumption may vary a bit between different vendors and implementation IC's.

Jow, thats a valid point. Yea, we didn't think of it. I think everyone should read this for an idea:

What do you think guys?

Catia V6 is coming out soon Ah, I didn't do the grooves in Google Sketch. Used Alibre for that. Though, I'll try working on G.Sketch more.

Ah shucks, I was looking forward for the threads.. better looking Besides, what steering method are we using? differential or rack & pinion?

[raj87verma88]

Rack and Pinion will be better

[raj87verma88]

Never heard of differential as a steering method. Rack an pinion is the most common steering design. You can get more detail on Car Bibles : The Car Steering Bible

[joe3204]

found a link for differential steering..seems wheel chairs use the same system

Thanks for the link joe.
@ash and xhx. It seems the project now progressing rapidly. I have some designs in my mind, but won't be able to put them to paper till the end of next month. I am going to join a Robotics course with Appin and will be paying the registration fee tomorrow. This is the link to their site and the course that I will join. Just go through it and tell me if my joining it will be any help to you.

Well, tanks essentially use differential steering

We could technically compromise with the tracks and wheels. How about using 6 wheels? (3 on each side). That'll still give us traction and avoid getting stuck over large bumps. Steering both the first pair and the last pair of wheels can give us awesome maneuverability too! I've seen some modern APC's designed like that. Oh btw guys, the robot doesnt have to go SO fast. Just less than walking speed is sufficient. Yes?

By the way, can you guys understand this stuff?

It got too complicated as I scrolled down =P

Dude, its an excellent course. Hopefully you'll gain a lot of experience from this =) And it'll help the CE Bot for sure!
