This simple and cost effective frame kit allows users to build their own projects onto the acrylic 2WD car frame. This kit comes with two 6v DC geared motors, two encoders, one frame, one 4x AA battery holder, a third wheel that will coast as the motors does the movements and a mount designed specifically for the ultrasonic rangefinder module that is sold separately. This frame is designed to be a front wheel drive system. All you need is an H-bridge, any microcontroller and a power source. Get it up and running with our simple guide on the assembly and visit any of our premade car kits on our website to download the free code provided for Arduino Uno, example codes such as line tracking, obstacle avoidance, IR Remote, Bluetooth and etcetera! Either use double side tape to build your projects onto the frame or use/drill additional holes provided on the frame.
