$45 Walmart App-Controlled R2-D2

in Robotics
I bought one to cannibalize for a paying project. Cheaper in-store at $45 vs $67 online. BT/iPhone/Android

A lot of actions in the video. It should make it into the project instead of into my collection. Or maybe I'll just buy another one for me the twins.

    Or $41 for an R/C BB-8. Get your droid on either way.

    Will def have to get another one for myself. First peek. Gotta learn more about the internal mechanicals. They are getting a lot of motions out of maybe 3 motors. FYI the first one I bought was defective (fell over a lot while moving and BT wouldn't pair) so I had to swap for this one, which works great.

    A purpose-built hackable version of this would be perfect for kids to learn to code.

    Best thing I've read all day. How is it on carpet?

    Why buy one when you can get two for twice the price?

    Not good, even on low-pile carpet. Those tiny rollers are great on smooth floors though.

    THAT's my kinda thinking. Mr. Hadden!

    I must add that this thing is heavy & solid, built like a brick outhouse. Still needs a laser or flamethrower, as most robots do.

    It did a mediocre figure 8 today. Not super repeatable between several attempts, but hey, it's a toy at a low price point. Dead reckoning is not listed as an integral feature. :) There's a GUI on the phone/tablet to connect blocky (!) commands together to make a sequence.

    This looks like somthing for the hacking table, if you have a good foundation and room for electronics, make it smart.

    EDIT: I forgot about it's under-designed drive system. It would look good in a Mechanum or Omni setup:

    EDIT2: Make me smart. ( line from a popular tv show.)

    Agreed! So when are you getting one? :)

    I have a trashcan the would look like R2, given the right paint job. I may go homemade, it's not beyond either one of us to use a trashcan as a receptacle for our creations:
