Robots have been around for decades, yet their definition remains subjective and varies from person to person, with no unified opinion. One reason for this ambiguity is that robots are still evolving, with new models and functions continuously emerging. Perhaps it is this vagueness in the definition of robots that allows for ample imagination and … Read more
The chilling frost wind enters the night, countless stars shine in the sky, the pipa plays a rapid tune of golden spears, and the heavenly sounds are accompanied by the drums… As the pipa plays, behind the night curtain, an unprecedented battle in the Internet of Things begins! Wireless communication technology has rapidly developed for … Read more
1 Introduction The purpose of this article is to provide an introductory technical overview of LoRa® and LoRaWAN™. Low Power Wide Area Networks (LPWAN) are expected to support a major part of the predicted billions of IoT devices. LoRaWAN™ is designed from the ground up, optimized for battery life, capacity, distance, and cost. An overview … Read more
BY：Author Arjun Nagarajan LoRaWAN is a remote wide area network protocol developed by the LoRa Alliance that connects “things” wirelessly to the Internet in regional, national, or global networks. This technology meets critical Internet of Things (IoT) requirements such as bi-directional communication, end-to-end security, mobility, and localization services. It defines the communication protocol and system … Read more
Recently, keywords like LPWAN have sparked a craze in the IoT field. With LPWAN, LoRa, and LoRaWAN having similar names, many people are confused about these three concepts. So today, let’s explore the differences and connections between them. LPWAN, also known as LPN, stands for Low Power Wide Area Network or Low Power Network, referring … Read more

Robots are not isolated systems; they are a set of distributed sensors and actuators, often running on resource-constrained small embedded devices (microcontrollers) that communicate via wired or wireless connections. However, mainstream robotic operating systems like ROS/ROS2 are too large and heavy, making them unsuitable for robotic scenarios based on microcontrollers with hard real-time requirements. Zephyr … Read more
