  • 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.

    I try to get my kids involved into robotics. There is only one problem. I have two daughters. They are interested but the things I build are not attractive to see so they are bored very fast.

    I have a Ultimaker 3D printer for a few months now (I will write about this someday) and they really like this thing. The girls only want to print dogs and the oldest one asked me to print a Aibo dog for her. Great idea but … maybe some other time.

    Last week I found something on the Internet what’s simple and looks great. I showed it to my kids and they loved it. It’s Called BOB the Biped. This is an open source project build by K.Biagini. You can find it at http://www.instructables.com/id/BoBtheBiPed/

    Below the parts I printed. Next on the todo list are the electronics.
