vector_ros

This repository contains an unofficial ROS package for Anki Vector that I started as a small side project after finishing several online ROS courses. This package is essentially a wrapping of core Vector functions from Vector SDK as ROS topics, services and actions(full list below). In order to showcase the package I wrote a simple red ball tracking node which subscribes to the camera feed coming from Vector, locates the red ball using cv_bridge/OpenCV and publish Twist messages to move the robot accurdenly as you can see in the following video:

General Overview

Vector ROS project is actually divided into three separated packages, which are:

vector_ros

• Main package, contains message service descriptors and example nodes, such as a red ball tracker.

vector_ros_driver

• Physical / "real" robot driver node - this node does the actual interface to Vector using Vector Python SDK.
• Notice this package was developed using Python 3.6 to work with Vector's SDK. 🐍
• Offers easy deployment using Docker! 🐳

cozmo_simulation

• Simulated robot package for both Cozmo and Vector, created by the guys at The Construct so we can use Vector in Gazebo.
• Video tutorial showing spawn simulated Vector in ROS Developers Studio

Setup With Physical Robot

You can find the full setup instructions at vector_ros_driver.

Topics

• /vector/camera (sensor_msgs/Image)

• /vector/set_head_angle

• /vector/set_lift_height

• /vector/anim_list

• /vector/say_text

Actions

FAQ

• Why isn't this XX from Vector SDK supported? Well, I didn't wrap all the functions from the SDK - only the main ones as i see it. Yet, if you found a missing function that you need/would like to see as part of vector_ros, please consider opening a new issue with your proposal.
