This tank/car chassis is assembled by ESP8266 WiFi module, Based on which, doit company has already designed and developed the mobile phone App with Android and iOS version. By the Apps, the tank/car chassis can finish some basic functions, such as, forward, left & right, back, and return. Doit company provides the richful documents, including the source code, which can let many developers, lovers, and students to DIY the wanted functions. More details, please see the "download" menu.


1) Reserve the space for 9g, MM95, MM96R gear;
2) Reserve for the intallation holes for UNO R3 and NodeMCU development board kit;
3) Reserve the space for robotic manipulator;
4) Design the LED light for the dark moving and brighten the light;
5) Add the 25mm and 37mm motor frame, can change the 4WD smart car; 
6) All the chassis are metal, excluding the track (plastic).
7) The chassis can bearing the weight is about below 5kg; we test the 2.3kg;
8) The bearing wheelpiece is connected by the stainless steel and two bearings, which can let the bearing wheel is rotate freely with small frictions.
