Recently I’ve had a few people ask me what type of laptop they would recommend for developing ROS applications. In my years working with ROS in a research capacity, I’ve used dozens of development machines! I’ve learned a few guidelines when picking out laptops for working with Linux, ROS, and robots. Following these guidelines when picking out a computer will make your ROS development experience far smoother.
You can use easily speech recognition to emit ROS messages and control your robots with your voice. In this post, we’ll learn how to install some popular speech recognition libraries on a ROS machine. This post describes how to set up the Sphinx libraries and custom code developed by human-robot interaction researchers at UT Austin and elsewhere.
In our robotics lab at UT Austin, we often use augmented reality (AR) tags to determine the position and orientation of an object. One good ROS package we use for tracking markers is
ar_track_alvar, which can track ArUco-style markers (shown below) and calculate their 6D pose. The package makes detecting AR tags as easy as running a
roslaunch file (with some slight configuration tweaks).
