01 / Under the shell
The specifications.
Hardware, build and software on one sheet. Every fact links to where we found it.
The repository contains course material for creating a real robotic arm controlled by voice using Amazon Alexa. The course covers Gazebo simulation, robot kinematics, ROS, MoveIt!, and using Arduino with ROS. The repository tree includes CAD and STL files for arm parts.
