+# LidarBot
+
+## DESCRIPTION
+
+<mark>LidarBot</mark> is a four-wheeled car based on indoor navigation. The car body is loaded with lidar, four Mecanum wheels, control-wheel bottom board(based on MEGA328), two RGB bars, M5Core(CarMainController) and some LEGO holes.
+
+Real-time communication via ESP-NOW between the car and the remote control handle. After receiving the control signal, the car master controlls the wheels and RGB bars through the specified protocol format.
+
+And in addition to controlling the car's flexible front, rear, left and right movements, the indoor terrain can also be displayed on the display screens of the car master(M5Core) and the remote control handle.
+
+## FEATURES
+
+- Lidar: 8m @ 6Hz
+- Programming Support
+   + Arduino
+- Compatible LEGO

+# LidarBot
+
+## 描述
+
+<mark>LidarBot</mark>是一款以室内导航为基础的四轮小车。车体装载了激光雷达、四个麦克纳姆轮、车轮控制低板(主控芯片是MEGA328)、前后RGB灯带(共16颗)、M5Core主控、多个LEGO孔。车与远程遥控手柄之间通过ESP-NOW实时通信，而小车主控接收到控制信号后，通过规定的协议格式实现控制车轮和RGB灯带等。除了能控制小车灵活地前后左右移动之外，还能在小车主控和手柄主控各自的显示屏上显示室内地形。
