Introduction

The RoboMaster S1 is an educational robot inspired by the DJITM RoboMaster competition. The S1 offers comprehensive control and an immersive driving experience thanks to the omnidirectional

chassis, agile Mecanum wheels, exible gimbal, and stable, low-latency image transmission in rst person view (FPV). Users can also target objects and battle other robots with the blaster.

The body of the S1 is covered in armor, and each piece has a hit detection module that can

instantly detect physical hits and feed back to the intelligent controller. The blaster provides highlevel accuracy and stability thanks to the 2-axis gimbal while the launch trajectory light gives users

a realistic and immersive experience.

The intelligent controller is integrated with multiple systems including a video transmission system, game system, and Scratch programming system. It includes six smart modules, including line recognition, vision marker recognition, person recognition, clapping recognition, gesture recognition, and S1 robot recognition.

The S1 supports Scratch and Python programming. With DJI’s project-based tutorials, users can

gradually master programming theory and robotics knowledge.

Setting the PWM Ports

PWM (pulse width modulation) controls the duration of a high level of output during a certain period, and is broadly used to control LEDs, navigation gears, and more. The S1 PWM port has a default

duty cycle of 7.5% and a fundamental frequency of 50 Hz.

For LEDs, the PWM output rate ranges from 0% to 100%, with 0% corresponding to an LED’s lowest brightness and 100% to its highest brightness. For navigation gears, the PWM output rate ranges from 2.5% to 12.5%.

You can set the navigation gear PWM output percentage based on the rotation angles you wish to control.

Each time the custom program or Python program nishes running, the PWM port output signal will be set to its default setting, which is 50 Hz and the duty cycle is 7.5%.
