Description

CrowBot BOLT is a programmable educational car that can be easily used. It is small and beautiful in shape and easy to install. It uses ESP32-WROVER-B as the MCU, with Bluetooth and WiFi functions. It has a wealth of sensors(such as photodiode, ultrasonic sensor, line Tracking Sensor), can quickly realize functions such as light chasing, line tracking, obstacle avoidance, remote control, and light show.
As an entry-level ESP32 programmed educational robot, the cool and cute Bolt makes robot programming learning, and teaching easy and fun. It comes with 16 lessons in three languages (Letscode, Ardunio, MicroPython), provides rich programming, and allows programming beginner to learn to program in the fun of creativity. It has reserved 2 expansion interfaces, which can be expanded and used with 150+ kinds of Crowtail modules. Unlimited creativity, waiting for you to discover!
