2018.08.31 Release Notes

Welcome, Misty I Developers!

This release is for Misty I CAN bus robots. It contains some new features as well as enhancements and changes to current capabilities. You can use either the Companion App or the API Explorer to perform an OTA (over the air) update of your Misty robot.

Important: Please keep Misty plugged in for the entire duration of the update and do not attempt to send commands to her during this time.

As always, we look forward to your feedback!

New Features

  • Ability to control the volume of Misty’s audio via both the API (SetDefaultVolume and PlayAudioClip commands) and Blockly (PlayAudioClip block with volume parameter).
  • Web server updates to enable better security, higher performance, and uploading of multi-part data.
  • Changes to websocket data formats for face detection and face recognition data. For skills using face detection or recognition, you should now subscribe to the ComputerVision websocket data type. The FaceDetection and FaceRecognition websocket data connections are now deprecated. Note that the format of data returned by the ComputerVision websocket differs sightly from those of FaceDetection and FaceRecognition. Read the docs here for more info.
  • Face training status messages are now displayed as pop-up messages in the API Explorer.

Bug Fixes & Improvements

  • Fixed issue with not being able to upload image or audio clips in Firefox browsers.
  • The Blockly ChangeDisplayImage block now accepts decimal values for the Alpha parameter, allowing images to have gradations of transparency between completely transparent and completely opaque.
  • Increased the duration before timeout in Blockly to allow for processing of large uploaded files.

Known Issues

  • Issues with the speed/reliability of data coming from the Occipital Structure Core depth sensor’s USB connection are causing the robot to have issues with successfully obtaining pose.
  • The covering for the time-of-flight sensors can create false positives for close distance detection, which causes the robot to refuse to move. A workaround is to force the robot to detect a further distance by standing in front of it.
  • The battery charger will only charge the robot if it is replugged into the robot after each time that the robot is turned on.
  • Inconsistent behavior with the LocomotionTrack API command when attempting to drive the robot backward.
  • Observed issues with consistently receiving data for websocket subscriptions. Rebooting the robot seems resolves this issue.
