Using RViz to Visualize Robot Trajectory on Local Machine
A robot is equipped with an STM32 microcontroller and a Jetson Nano. The STM32 handles motor control and reads data from global positioning sensors, transmitting this information to the Jetson Nano. On the Nano, a node publishes global coordinates, while a subscriber node runs on a local computer to visualize the robot's movement path via RViz. ...
