Look into RC cars ( Brushless ones ) for small suspensions.

Also Dagu makes a all terrain chassis .. will thumper.

Mainly depend on the the obstacles you wish to overcome and your budget. Post more details and you will get more answers.

The suspension setup you will want will depend on the parts, tools and services you have access to.

Take a look at the following links -

The second link may not be suitable for you purpose, but just wanted to let you know that what suspension setup you want is limited only by your imagination.

I guess you meant the Wild Thumper from DAGU.

It will be a very cheap robot . And d suspension should be able to withstand big bumps as well as mud etc

Total Budget in Rs will be helpful , Cheap and All terrain do not really mix.

I have the motors and all that......the tyres are also there.......so apart from that its around a 1000 bucks for the suspension setup and construction of the chasis

I've been to 3-4 all terrain competitions and i can surely give you some ideas which observed and developed:

1. Track Belt with 150-200 RPM motors work well.
2. Try and Keep the centre of gravity around the center of chassis.
3. Add extra small wheels which can be grounded while you coming off an inclination.

For suspension look into this:

@Op: RC suspension parts are pretty cheap here, you can build a suspension for less then 20 (< Rs. 1500). Sites like these (clickie) (http://www.nitrogenrc.com/Rc-Spare-Parts/Rc-Suspension-Parts) sell them. I don't know much about where you can get them in India, but I'm rather sure they are available, I used to frequent this RC club we used to meet at an open area near Dwarka (New Delhi) every Sunday; most members flew nitro powered planes, but I did see some people with RC cars, and all of them had intricate suspensions. If you are at university, you could ask around if they have any clubs, I'm sure they would lend you the parts.
