Waveshare JetBot AI Kit, AI Robot Based on Jetson Nano Overview Smart robot is always the favorite project of electronic enthusiasts, however, a robot will be "not that smart" if it is not AI-based. Welcome the JetBot, an actual smart robot powered by Jetson Nano. With the intelligent eye (front camera), facial recognition, object tracking, auto line following, and collision avoidance can be easily achieved. It also comes with ROS nodes code, which makes it easy to get started with the open source ROS (Robot Operating System), and to learn the system framework and concepts of ROS. Features 1. Adopts 3x 18650 batteries (NOT included), high battery capacity, up to 12.6V voltage output, more powerful driving force. 2. Integrates S-8254AA + AO4407A lithium battery protection circuit, provides protections for over-charge, over-discharge, over-current, and short circuit. 3. Onboard APW7313 voltage regulator, provides stable 5V voltage for the Jetson Nano. 4. Onboard TB6612FNG dual H-bridge motor driver. 5. Onboard 0.91inch 128×32 pixels OLED, allows to display robot IP address, RAM, battery life, etc. 6. Onboard ADS1115 AD acquisition chip for monitoring the battery in real time. 7.
