• Join Hangouts Meet https://meet.google.com/hey-jxuo-esf
• Or join by phone ‪+1 405-586-5598‬ ‬ PIN: ‪682 931 335 #

Why

• Talk robots & related stuff.
• Make it easier for people to attend DPRG remotely.

Agenda

• Round table – everybody spends a couple minutes telling what projects they’re working on.
• Ad-hoc presentations – Whoever would like to show & tell.
• “Stump the club” Challenges – Ask for help if you’ve hit a roadblock in your project. Somebody in the club can probably get you pointed in a good direction – or even arrange a side bar session to help.

Note: We record a video of these sessions and post them on the DPRG YouTube channel. By joining the meeting, you’re giving consent to be included in the recording.
