Description

CrowBot BOLT is an open source smart programming robot car powered by an ESP32 chip. It has a wealth of sensors(such as a light sensor, ultrasonic sensor, and line Tracking Sensor), comes with Wifi and Bluetooth-compatible functions, and can meet a variety of programming environments like Letscode, Micropython, and Arduino. This programming robot kit can quickly realize functions such as light tracking, line tracking, obstacle avoidance, remote control, and light show. As an entry-level STEAM educational robot car toy, the cool and cute BOLT makes robot programming learning and teaching easy and fun. It comes with 16 lessons in three languages (Letscode, Arduino, MicroPython), provides rich graphical programming, and allows programming beginners 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!

This is an open source robot car, all design files can be downloaded below.

CrowBot's ultrasonic sensors can not only automatically avoid obstacles, but also emit colorful RGB lights. The unique design gives it more creative possibilities.

programming robot structure

CrowBot uses acrylic plate as the shell, and the assembly is simple, just align the positioning holes or slots, and tighten the screws to complete.

It can use an infrared remote or a Bluetooth-compatible joystick to control. These two methods have flexible control and can change direction at any time.

steam robot instructions

Button 1 (Ultrasonic Obstacle Avoidance Robot) When the distance between the BOLT and the obstacle in front is less than 30cm, the car will turn right; otherwise, it will always keep moving forward. And at the same time, the sensor has built-in RGB lights, which can emit colorful light sources.	Button 2 （Line tracking robot） Press the button 2, the car starts to follow the black line on the map, turn right when it deviates to the left, turn left when it deviates to the right, and back up when it exceeds the black line.

Button 3 （Light chasing robot） When use the flashlight to shine in front of the BOLT car, it can distinguish the moving direction according to the light intensity to realize the effect of the light-chasing robot.	Button 4 (Music playing robot) Press the button 4, the 4 onboard RGB_LEDs of the BOLT randomly display different colors and present the effect of flowing water lights. Apart from these, it can also play music at the same time.

The Type C interface at the bottom is plug-and-play for quick programming and more creativity.
