## Description

**RoverC-Pro** is a programmable Mecanum wheel omnidirectional mobile robot base. Compatible with M5StickC/M5StickC PLUS, it can be initialised by just inserting M5StickC/M5StickC PLUS. The main control chip is STM32F030C6T6, and it incorporates four N20 worm gear motors to drive the wheels directly by the motor driver. 

The PRO version provides a gripping mechanism controlled by a servo for gripping objects. The base provides two dedicated servo control drivers. In addition, it also provides two Grove-compatible I2C connectors to facilitate the expansion of other modules. The base is compatible with Lego and can be expanded structurally. There is an 16340 (700mAh) battery on the back, from which the battery can be replaced. It can be recharged through M5StickC/M5StickC PLUS. The power of the base is controlled by an independent switch.

## EasyLoader

>EasyLoader is a concise and fast program writer, which has a built-in case program related to the product. It can be burned to the main control by simple steps to perform a series of function verification. Please install the corresponding driver according to the device type. M5Core host [Please click here to view the CP210X driver installation tutorial](en/arduino/arduino_development), M5StickC/V/T/ATOM series can be used without driver)

   </div>
</el-card>

- Note: Before use, please make sure that the roverc is fully charged. Charging method: insert m5stickc into the roverc, and connect the USB cable for charging.
Burn the easyloader firmware of Joyc and roverc with two M5StickC respectively. Insert Joyc and roverc respectively after burning. After power on, roverc will display the MAC address name and battery power. At the same time, Joyc will scan the MAC address name of roverc. Long press the a key of M5StickC on Joyc, and the work will be matched. Left rocker up and down control front and back, left and right control translation, right rocker left and right control steering.

?>2: This case is a RoverC stand-alone control program, which is directly controlled by the main controller. Please select the corresponding case program below according to the equipment you are using.
