The need for seamless remote interaction in various fields has driven the development of advanced telepresence solutions. Our telepresence robot leverages WebRTC for real-time video communication and MQTT for control signals, providing an innovative approach to remote communication and operation.
Highlight
- Integrated WebRTC for real-time video calling to enable seamless communication.
- Used MQTT for control signals, ensuring efficient and reliable robot operation.
- Enabled remote control of the telepresence robot, allowing users to drive, rotate the camera, and operate 7-DOF robotic arms from anywhere.
- Provided multiple control options including web interface buttons, keyboard, gamepad, and custom controller gloves.
- Established a database for user roles (regular, robot, admin) to ensure only authorized users can control the robot.
- Equipped the robot with a multi-camera setup for comprehensive environmental awareness.
- Implemented ultrasonic sensors for obstacle detection in four directions to avoid collisions.
- Facilitated bidirectional communication through the robot's display, microphone, and speaker.
Challenge
The lack of a comprehensive telepresence solution that integrates real-time communication, versatile control options, and robust safety features makes it challenging to interact and operate remotely in diverse environments. Ensuring low-latency communication and reliable control over the internet, while maintaining user-friendly operation and preventing collisions, is particularly difficult.
Solution
Our team developed a telepresence robot that leverages WebRTC for real-time video communication and MQTT for control signals. This innovative system allows for remote control via a Django-based web interface, keyboard, gamepad, or custom controller gloves. The robot features five cameras for a full view of the surroundings and ultrasonic sensors for obstacle detection.
Real-time communication is enabled using WebRTC, providing low-latency video calling. The system incorporates a robust user role management database to ensure that only authorized users can control the robot, enhancing security. The robot's advanced capabilities include the ability to have conversations, drive around, and interact with objects using robotic arms. Flexible control options, such as web application buttons, keyboard, gamepad, or custom gloves, cater to different user preferences. The comprehensive surveillance system utilizes multiple cameras and ultrasonic sensors to provide environmental awareness and collision avoidance. Additionally, remote management allows users to control the robot and its features from anywhere in the world.
