Wild Thumper 6WD all terrain chassis【限量】

本商品為研發實驗用的模組，無法隨插即用，須經專業背景人士（如：工程師、研究生、師生）撰寫程式、燒錄、接線等二次加工後，才具備訊號傳輸功能。 並非直接插電後可直接使用之射頻模組，非屬電信管制射頻器材，購買前請詳閱商品說明。

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 for an Advanced Robot.

The Kit now includes 2x Quadrature Magnetic Wheel Encoders that can be optionally mounted. These can be used to perform accurate speed control, essential in advanced Robotics application.

The 6WD chassis has wicked spiked 120mm diameter wheels and an anodized aluminium chassis made from 2mm thick plate. Each of the six motors are mounted on independent suspension and outfitted with 34:1 steel gearboxes.
The chassis has 4mm diameter holes punched every 10mm and there is plenty of room interior to the chassis for batteries, drivers and other support hardware: two chassis segments between the wheels have been designed to hold 7.2V sub C battery packs (not included) as used in many RC cars. A total of 4x 7.2V battery packs can be fitted if necessary.

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 manoeuvrable your platform will be.

To control the Wild Thumper, DAGU has created a souped-up 16Amp Arduino DC Motor Controller (more details here). If you wish to add this board to your purchase please select the option in the end of this page.
