Philly Robotics August 2010 Meetup Summary

From: Roy B
Sent on: Saturday, September 4, 2010 12:12 PM
We were back to our usual home at the Hive last month. Here are the highlights of the meeting:


  • We discussed ideas for our club - PhRoG: the Philadelphia Robotics Group. There is a website, but its not quite ready for prime time. We're still looking for logo ideas - something that ideally combines robotics with frogs and or Philadelphia. Thanks to Glen for hosting the site and Daniel for working on some of the code.
  • Glen demoed his delta bot mechanical prototype, built using servos and custom linkages. It doesn't yet have the forward or inverse kinematics driving software, but it will.
  • I showed my quadrotor components - motors, speed controllers, propellers, frame and .
  • We helped new member Priyank find some on-line places to get his robotics gear (sorry - there aren't any local stores that we're aware of that have any components - unless you count Radio Shack and possibly some R/C - type hobby shops)
  • Nelson showed us a Mathematica Notebook that demonstrated the sonar location beacon calculations. He also told us why it was important that all the beacons do not lie in the same plane (you'll lose information about the third dimension)
  • David and Jack are two high school FiRST robotics team members who stopped by for some tips


Also, some of us were fortunate enough to take a field trip to the U Penn GRASP lab and witness those aggressively maneuvering quadrotors (http://fling.seas.upenn.edu/~dmel/wiki/index.php?n=Main.Quadrotor) in person, as well as some other robot projects in different parts of the lab. We should have some pictures up shortly. I don't want to spoil the surprise, but the next round of YouTube videos will astound you!

Please let me know if I've left anything out, or if you have anything you'd like to present, demo, or discuss at the next meetup.

I hope to see you next week!
- Roy
