Per Quiet, approx 20% of picks are high picks requiring a 3-step ladder to reach. High picks may increase to 40% of picks during peak. Pickers spend significant time searching for ladders. Hanging a ladder on the bot would save time (and also currently supported by competior 6 River used at a Quiet site).
Key req'ts for hanging ladder
Provide quick & easy method to “securely” attach the top and middle/bottom, so bottom of ladder does not swing out when bot makes quick turn/rotation
One concept that has been mentioned is to use Velcro or a similar method to securely attach the ladder to the mast
Hanger accessory must not present potential safety hazard to employees (avoid sharp edges, pinch points)
Ladder must be positioned so it does not block sensors, cameras, e-Stop, etc.
Ladder must "not" restrict access to e-Stop on top mast
Violates Origin safety
