Data Playback

  • Replay a recorded episode straight in the browser from the file manager: multiple camera videos, audio, and sensor charts together.
  • A sidebar sensor selector and a multi-camera grid; the timeline scales to the clip length and the scroll wheel seeks quickly; phones and tablets adapt automatically.

Batch Export & Transfers

  • Select several recordings and export them at once — as a single ZIP, or one file per recording.
  • Uploads and exports share one view, with a "reset" action that clears all transfer state in one click (uploaded marks are kept); in-progress transfers resume on their own after a page refresh.
  • A dedicated column shows each recording's upload status at a glance.
  • Recordings larger than 4 GB now export and upload correctly.

Trustworthy Recordings

  • Each recording captures its own configuration the moment it starts, and the exported metadata reflects exactly what was recorded.
  • Data-integrity information is written safely as the recording proceeds, so an unexpected interruption cannot corrupt it.
  • A sensor that captured no data is now clearly marked as an error instead of appearing normal.

Grippers & Sensors

  • The IMU and the gripper's built-in IMU now sample at 240 Hz for finer motion detail (video conversion matches).
  • The gripper has a recording indicator light — it blinks while recording and is off during preview and standby.
  • Calibrate the gripper's magnetic encoder in one click from the configuration page, with an "irreversible" warning beforehand and a clear reason if it fails.
  • Playback charts and MCAP output no longer include the unused magnetometer data.
  • System settings now show the device serial number.

Firmware Upgrades

  • Firmware is delivered through a new pipeline with a task queue and install history, so upgrades apply in order and each step can be traced and diagnosed. The device warns you not to cut power during the upgrade restart.
  • New firmware is available for the head-hub IMU and the gripper's magnetic encoder.
  • Connect every gripper and the head hub before starting a firmware install. Each connected device is flashed in turn; any device left unplugged is skipped, so make sure all grippers and the head hub are attached first.

Stability

  • Grippers and IMUs are reliable straight from a cold boot: no more capture hangs, offline sensors, or false error alarms in the first moments after power-on.
  • Unplugging and replugging a gripper or IMU now recovers on its own — the sensor comes back without restarting anything.
  • Alarms sound only while recording and clear the instant you stop; the recording state (starting / recording / stopping) is shown clearly, and a failed start returns cleanly to idle.
  • Turning live preview on and off is reliable, with no leftover or stale video connections.
  • Setting the IMU sample rate no longer freezes the sensors.

Responsiveness

  • The interface stays smooth even while the device is trimming, compressing, or uploading — status and metrics no longer wait behind disk work.
  • Fixed the occasional "Network Error / request failed" messages seen when the device was idle or busy, and the broken live updates after refreshing a deep link.

Data Quality

  • Fixed the first recording after a cold boot exporting with a wrong, low frame rate and gaps in its timeline.

Interface & Configuration

  • While recording or previewing, actions that would interrupt it are greyed out with a tooltip, and leaving the page during a transfer asks for confirmation first.
  • Recording start/stop and countdown cues play from pre-recorded audio, so the English and Chinese prompts are clear and never overlap.
  • Each camera model starts at a resolution it actually supports, reducing manual adjustment.
  • The mobile control tab is simpler, without the redundant sensor-status panel.
  • System logs rotate by size, so they can't fill the disk.
