ROS2 Humble MPU6050 IMU Sensor Interface for NVIDIA Jetson Nano
Content:
Integrating reliable sensors with powerful computing platforms is crucial for achieving precise control and navigation. In this article, we delve into the integration of ROS2 (Robot Operating System 2) with the MPU6050 IMU (Inertial Measurement Unit) sensor for the NVIDIA Jetson Nano.
Introduction to MPU6050:
The MPU6050 is a versatile IMU sensor capable of measuring acceleration and rotation. Its compact size, low power consumption, and high accuracy make it a preferred choice for motion sensing in robotics, drones, and wearable devices.
Interfacing MPU6050 with ROS2:
This ROS2 package interfaces with an MPU6050 sensor via I2C, calibrating upon node startup. However, the quaternion part of the IMU ROS message is presently set to zero.
