Description: This is easily the most rugged and beefy robot chassis in its price range. The Wild Thumper 6-Wheel platform is the best of both worlds: It takes almost no time to go from un-boxing to rolling chassis, but it’s also ready to be expanded on and makes great base stock for a serious ‘bot.
Each of the six motors are mounted on independent suspension and outfitted with 34:1 steel gearboxes (no more stripped gears!). The motors are wired together on a terminal strip inside the 2mm thick anodized metal frame and can be controlled on two channels (left and right). The entire chassis is perforated with 10mm pitched, 4mm diameter mounting holes and there is plenty of room interior to the chassis for batteries, drivers and other support hardware. The chassis comes with 6 of those gnarly Dagu 120mm off-road wheels.
Because there are six motors total, each channel of your motor driver will need to be able to supply a decent amount of current to get things moving. This is a differential drive platform, meaning that a turn in accomplished by simply driving one side faster or slower than the other, or turning the two sides in opposite directions. Because the “pivot point” of this turn is essentially made up of the opposing three tires a gradual turn will require less power than a sharp one and the more power you can source, the more maneuverable your platform will be.
We have had success driving this platform with the SparkFun Monster Moto Shield, it can be found in the Recommended Products section below.

There’s plenty of room for batteries and controller. Lots of holes for mounting almost anything within reason.

The frame is great as it has lots of room for batteries and other stuff and it’s fully customizable so you can interchange parts however you like.
The axel coming from the gear-box is really weak. When the internal part of the axel breaks (and it will) it results in a lot of unusual play.
Other than that, this is a great product. Just not worth the steep price.
