    TurtleBot-like hardware platform?

    Hi all,

    I love the idea of the TurtleBot kit available from Willow Garage. Unfortunately, they won't sell "just the hardware"; i.e., I'd love to get the platform hardware to bolt onto my Create...
  6. Re: Recommended 24V Battery for laser scanner?

    Ended up going with the flat 24V battery and charger...will need the extra power anyways for other servos and such...thanks for the suggestion nonetheless.

  7. Re: Recommended 24V Battery for laser scanner?

    Thanks for the fast response. The SICK S300 has a power on current of 2 A with normal operating around .25 A to .33 A. The max load is 1.65 A during operation. Power consumption ranges from a min...

  9. Recommended 24V Battery for laser scanner?

    That was my biggest concern as well; I bet I can figure something out to mount it to the top of a frame instead of in front of it using this frame set and some 90 degree bracket to mount between the...

    Would Eddie's suggestion work with the 8/8/8? Furthermore, I'm finding that the sensors need from 3-5 range cycles to properly calibrate to give a reliable reading. Does Eddie's approach bypass the...
