Hi, I'm Kentaro!
Here is the story behind Labelme.
I built it when I was at the end of my bachelor's degree / beginning of my master's. I was working in a robotics lab and created it to teach my robot to see the world.
Around 2015-2016, Amazon Robotics held the Amazon Picking Challenge (APC) shortly after acquiring Kiva Robotics, the company who developed the AGVs used at Amazon. They had automated material delivery in warehouses but were looking for an automation solution for material picking.
We participated as a team from the lab (Can you spot me in the picture?), and I ended up building Labelme for the challenge.
For the full story, check out my tweet.
