Live Tracker — Recording Robot Moves via the Flair 7 Mimic Window

Summary

Once the Live Tracker app is connected and the robot responds to device movement, moves can be recorded directly using the Mimic window in Flair 7. The workflow is: open Mimic Settings and switch all axes to LEARN (including focus), then click Record in the Mimic window. Use the Tracker App to perform the move — when you release the green button on the app to halt the robot, it also stops recording in the Mimic window. Clicking Use Recording captures the move. The resulting move has limited editability in the current version (editing functionality is planned for a future update). For more precise alignment, zeroing the iPhone at a fixed known position and calculating the offset to the robot's zero is the more robust approach.

Symptoms

  • Live Tracker connected and robot responding to iPad/iPhone, but no obvious way to record the move.
  • Move plays back but cannot be edited or saved as keyframes.
  • Zeroing and offsets from device position to camera position are unclear.
  • End of recorded move has unexpected behaviour or causes the move to fail.

[WORKAROUND] Record via Flair 7 Mimic Window — All Axes Set to LEARN

2024-07-19 — Tom D

This is the confirmed Flair 7 workflow for recording a Live Tracker move:

  1. In Flair 7, open Mimic Settings.
  2. Switch all axes to LEARN — including the focus axis. This tells Flair to record the physical axis positions as they change.
  3. In the Mimic window, click Record.
  4. Use the Tracker App to perform the move (press and hold the green button while moving).
  5. When you release the green button in the app to stop the robot, the Mimic window recording also halts.
  6. In the Mimic window, click Use Recording.
  7. Preview the move in the 3D rig view and run it.

Tom D: "Actually it's just got a lot easier and simpler in some respects — in the Flair 7 open mimic settings. You'll see a list of axis that you'll want to switch all to LEARN (all the way down to focus axis). Then with the live tracker all connected, select record in the mimic window, use the app to manipulate robot for your move and when you release the green button on the app to stop the robot, it will also halt the recording in the mimic window. Then click 'use recording' in the mimic window..."

[INFORMATIONAL] Move Editing After Recording Is Limited — Future Update Planned

2024-07-19 — Tom D / Niko

Moves recorded via this method have limited editability. The raw recorded data does not have discrete editable keyframes in the way a manually-programmed move would. Niko noted that this is where the workflow "becomes a bit messy." Full editing functionality was described as planned for a future update.

Niko: "Tom, I agree that's the way with the easiest workflow. But if you want to edit the movement, things will become a bit messy." Tom D: "I believe that functionality for editing the move is coming in future update."

[INFORMATIONAL] Alternative: Zero iPhone at Fixed Position and Measure Offset

2024-07-19 — Niko

For more precise and repeatable results, Niko recommends zeroing the iPhone/iPad at a fixed, measured position and calculating the exact offset from that position to the Bolt's home/zero point. This allows the recorded move to align accurately with the real-world camera position.

  • Place the phone in a repeatable holder/mount at a known location
  • Zero the phone in the app at that location
  • Measure the physical offset from that position to where the camera sits on the robot at home
  • Keep the phone completely static during zeroing (not moving it through space first)

Niko: "You need to put the iPad or iPhone always in the same position, do the zero on the iPad and measure the offset to the zero of the bolt...The iPad or iPhone need to be static."

WhatsApp Excerpts

[19/7/2024] Josh Ellis-Tufts: Does anybody have a workflow figured out for using the live tracker for recording moves? I have it all connected and flair and the robot are responding to the app, however I can't figure out how to get the zeroing and offsets correct for a recorded move to line up with the current camera position.

[19/7/2024] Tom D: There sometimes is some funny business at the end of the move that causes it to fail that should be ironed out in another update
[19/7/2024] Niko: Tom, I agree that's the way with the easiest workflow. But if you want to edit the movement, things will become a bit messy
