I think this is a shot of the stocking area (note: blue robots). </div><div><br></div><div>One confusing shot shows a red bin in the grid (see 0:41).

It must be pretty flexible to handle all of the various types of products. I wonder if they use a load cell to verify if the robot picked up the correct amount of an item or in fact the correct item.</div><div>Ezra, thanks for sharing.</div><div>Regards,</div><div>Doug P.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Sep 10, 2019 at 10:26 AM Ezra Christensen via DPRGlist <<a href="mailto:dprglist@lists.dprg.org" target="_blank">dprglist@lists.dprg.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">A friend and I are working on Lego sorting bots, and I remembered this approach to pick-and-pull out of the UK. <br><br>Thought some others might enjoy it.<br clear="all"><div><a href="https://www.youtube.com/watch?v=4DKrcpa8Z_E" target="_blank">https://www.youtube.com/watch?v=4DKrcpa8Z_E</a> </div><div><br></div><div> <br></div>-- <br><div dir="ltr" class="gmail-m_-6959315607345837029gmail-m_3726371955478305237gmail-m_-721254468005246284gmail_signature">Ezra</div></div>
