API review

Proposer: Melonee Wise

Present at review:


The joy/Joy msg is currently in the joy package requiring all packages to depend on the joy package. This migration would eliminate the package dependency on joy and follow the ROS guidelines for separating out general purpose msgs in to msg packages. Additionally the joy/Joy msg lacks a header which is important for synchronization and several users have requested a header be added to the joy/Joy msg.

Based on the above feedback I will move the joy msg to sensor_msgs and add the header.
