  • BOB the Biped legs

    While printing the inMoov robot I made some progress on BOB the Biped. This is an open source project build by K.Biagini. You can find it at http://www.instructables.com/id/BoBtheBiPed/

    To build BOB you have to print 6 parts on a 3D printer. BOB has four servo’s. Two for each leg and is powered by 4 AAA sized batteries.

    Part list

    • 3D printed parts
    • 4 small servo motors
    • Battery holder for 4 AAA batteries
    • Arduino Pro Mini (5V)
    • Distance Meter
    • Wires
    • Small breadboard

    Printing the parts
    BOB has only 6 parts. The base plate, the head, two brackets and two foots. I used a Ultimaker printer to make the parts and took a day to print. I am planning to make two of them. One red and one pink. I have two daughters. The parts have a tight fit so you need to sand it down a bit.

    Mounting the parts
    I used small servo’s from Tower Pro. There are three screws in the package. I used two to mount the servo lever to the L-shaped bracket. The four spare screws from the four servo’s are used for mounting the two servo’s on the feet. I used hot glue to fix the servo’s to the base plate.

    As you can see on the photo, I soldered a 3 pin connector on the wires of the servos.

  • Print, Print, Print,……

    As always I print only during the daytime. The Ultimaker 1 is a fine printer, but it produces just too much noise to print at night.

    The inMoov Robot has a lot of part. Below the progress of the printing a few weekends. I think my robot is not ready in a few weeks, but is coming along. Just print, print, print……

    (Maybe I should purchase the Ultimaker 2. Less noise)
