Rocos Agent v1.7.1

19th June, 2023

  • Flow Component: Notification nodes added.
  • Flow Component: Naming convention updated to differentiate nodes from classes.
  • Flow Component: Generate UUID native entry point added.
  • Flow Component: Unix Nano timestamp entry point added.

Now a fallback option is included where the dock fiducial simply needs to be present in Spot's map. Navigating in front of the dock is then able to be carried out before docking.
Warning

The return to dock services (/spot/docking/navigateAndDock, and /spot/graphnav/navigateNextToDock) include a known bug with the Unstable Release 1.7.1. It is an edge case which will cause the agent to crash if there is no GraphNav graph loaded on Spot. The agent release for v1.7.3 contains the fix for this.

  • Spot Component: Freeze Spot service added. This allows posing Spot in its "freeze" mode where the legs are locked in place.
  • Map Component: Map component updated to allow ingesting robot map data into a DroneDeploy format. This can then be stored in the cloud. From here it can then be deployed back down to robots as required.
  • Leica Component: Static Pose services added to Leica Component.

When upgrading an Agent from a version older than v1.3.0, you will need to make some alterations to the configuration on the Agent Settings page in the Rocos portal at the same time.

  1. The component which was previously named "teleop-sender" is now named "telemetry-sender". Find the configuration entry for this plugin and change the "id" setting accordingly.
  2. The component which was previously named "teleop-receiver" is now named "control-receiver". Find the configuration entry for this plugin and change the "id" setting accordingly.
  3. In order to use the new Commands and Events functionality supported by the Agent, you will need to add appropriate sections Agent plugin configuration to enable the "command-receiver", "command-executor", and "events" plugins.
