Encoder for my robot chassis

This is the original kit I'm expanding on from ebay, pretty cheap, it said it had encoders, ive never used one, but it only came with disks for use with an encoder.

I still haven't received all the sensors ive bought but they are mostly not late, I expext withinthe next 7 days.

But Ive almost ordered these encoders , I hope they work out, unless you can suggest better in the next few hours. http://www.ebay.com.au/itm/Motor-Smart-Robot-Car-Chassis-Kit-Speed-Encoder-Battery-Box-for-Arduino-C99D-/231242762899?pt=LH_DefaultDomain_15&hash=item35d7248a93

Thanks,
Whiteoxe.

EDIT: I am much used to large style metal fab. Ive done many miles of welding stick and mig on farms building all kinds of things, steel feedlots to unique V6 motor self propelled grain auger we could drive around, and a hydraulic cattle crush operated by remote levers. but when it comes to little things ands no welding I'm slow. What would your tips be to mount a second level on this chassis ?

    Mike both those links take me to a robot chassis.

    Sorry....... here they are http://www.dx.com/p/speed-detection-encoder-pcb-module-for-arduino-green-152665#.U9SSjmflpdh

    my camera battery is in the charger, I just tried to take a close up of my soldering and the damned thing was flat !

    Those encoders should work as long as you can mount them over the encoder wheel. They only provide speed information, not direction, but that should not be a problem since the microcontroller that receives the speed signal also controls the direction signal going to the motors.

    The chassis looks like it may be MDF or plywood so you could use the same material for the second level deck and mount it using metal or plastic standoffs. Pipe/tubing from a plumbing supplier works well for this. If you want the upper deck to be the same shape as the lower one you can use a router and the lower deck as a guide to shape it. The 4' x 4' sheets of 1/4" floor underlay are a good choice for this kind of thing. They are inexpensive, smooth, and splinter free.

    If you look down on the page a ways, you'll see the clear plastic chassis. The wood appearance if from the protective paper. Not that this matters much. Your idea of using plywood as a second layer is still valid. The plywood used to build radio controlled airplanes is also good for making robots. The 3mm stuff is about right for holding electronics.

    I agree about the encoders. They should work if they fit. It's not clear they will fit though.
