    Features At A Glance

    The Cobra Flex is a universal modular Drive-by-Wire chassis with strong off-road crossing ability and shock-absorbing performance, open source all code for secondary development. It supports multiple host computers (Raspberry Pi, Jetson Orin Nano, etc.), the host computer can communicate with the chassis through USB or serial port. The four wheels are driven by 4x bus hub motors with built-in FOC control circuit, which provide strong power and smooth running speed.
    Built in Lithium battery set with 6x 18650 Lithium batteries, which provides uninterruptible power for the robot and supports charging and power output at the same time. Built in multi-functional robot driver board based on ESP32, adopts strong and weak electric isolation design and supports connecting bus servos, with onboard Wi-Fi (only for short-distance debugging) and Bluetooth. Adopts compact four-wheel independent suspension with CNC process, can easily meet the needs of heavy loads, shock absorption, and off-road. Also, it comes with 2 x 1020 European standard profile rails, providing more possibilities for secondary development.

    All Metal Compact Body with Extra-large Internal Space

    Adopts independent suspension structure and hub motor design, significantly optimizing the internal space of the chassis. Built in a battery set consisting of 6x 18650 Lithium batteries (3s2p), ensuring long runtime while also providing enough space for installing Raspberry Pi, Jetson Orin series or other host computers, and camera module, etc. Users can also freely plan the use of the space according to their actual needs.
