In our earlier post, I discussed reading joystick input in a ROS node. Now, I’m interested in learning how to utilize the joystick values to control the motors. Hardware There are two types of motors on board: a servo for steering and a DC motor for throttle control. Both are connected to an Electric Speed …
Let’s get started with writing our first ROS 2 node! This particular node will be responsible for publishing commands received from the Bluetooth controller, and we will create a new message type for it using C++. If you’re new to ROS 2 nodes, I highly recommend taking some time to familiarize yourself with the basics. …
