Need parts suggestion please

Hello,
I am working on some arduino small projects for now, and I am looking to buy a 4 wheel chassis and parts for my new project.

I am interest by your Iron Man 2 chassis with motors.

Can you tell me witch motor controller is the right one to order?
Can you tell me the right battery is good for this kit?

I wish to add the robot arm and the 3 sensors for obstacle to add on it like the PDF file picture of the Iron Man 2 documentation.

Can you give me all the parts I need please?

For the controller, I think I will begin with arduino uno, but if required, I can buy a better one.

Thanks for your help!

Hi Jean,

Regarding the chassis, it’s to be aware that it doesn’t have any encoders so for accurate positioning the might not be the best.
We have the Lynxmotion A4WD1 which is available with encoders (here).

There are no arm that will bolt directly to the Iron Man chassis, do you have an arm already or looking for one ?
All the information available from it’s manufacturer are available in the “Useful Links” section of the product.

All the best,
