Happy Thanksgiving from RUS

Happy Thanksgiving Day from Robotics Under the Stole!

This year I am especially thankful for this wonderful and discovery-filled hobby that has allowed me to make new friends around the world. Thanks to all of you for helping me explore something I love!

This list is too long to include here, but you all know who you are! You've written some of my favorite books, magazine articles, programs, help me on forums, created and produced products, educational materials, and corresponded with me from the beginning. You have been my teachers, cheerleaders, inspiration, and companions on this journey of joy and exploration. I am so thankful for all of you!

Arlo Modification - Getting a Grip!

Arlo modification from McMaster-Carr. I like Arlo's looks without the top platform (at least till I need it!). These rack-style pulls add a nice touch and are very practical. Here is a photo of them sitting on the platform for trying to figure out where best to mount them.

They are very sturdy pulls - as needed for this heavy bot! (especially when using two SLA batteries). The part number is shown on receipt above. No minimum order with McMaster-Carr, but with shipping - the two pulls (and the bright Phillips head screws and grommets that came with the pulls) cost about $30. The shipping was about 1/2 the cost.

Above, the Round Grip Pull Handles all mounted now! They work perfectly - These use the same (4) - ¼”-20 x ¾”, flat-head, black, socket-head screws (#710-00034) used to mount the motors and/or the top deck. All I did was drill the extra holes and countersink the holes for the screws (on the bottom of the Arlo platform). Super sturdy and really handy for picking up the robot. The Anodized Aluminum finish of the pulls are a perfect match with the wheels and Ping))) stands. 

Note: The pulls do not need to be removed to mount the top platform either. Though I would need to order four more screws.

Wouldn't this be fun? Signed up to be an early adaptor... See -

Hat tip to my pal, erco. He posted this on the Parallax Forums under the heading, "I Need a Man Bun!" My reply, "I don't have enough hair for a man bun, but I do have a home that would welcome a personal robot!"
