    as per above I posted above this is 2 pieces and needed to be glued together. Since I use ABS plastic for my prints. Splitting is a real problem for tall thin items which only get worse for really all items. Lower shrinkage plastic – like PLA may work better for a combined part.
    I consider this version a prototype and I have decided to start work…[Read more]

    I printed the forearm as two pieces for top and bottom (4 pieces total) and glued together as per instructions. Since I print with ABS plastic , I typically use the acetone glue method, however for the top and bottom of the forearm the mating surfaces don’t have uniform contact so the joint was weak. So after tacking with acetone glue I injected…[Read more]

  • So far in this project I have converted all the right hand stl files to CAD files (I use inventor). I have had to make many corrections and additions to make things fit right as well as fix weak areas in the prints using thin (0.8mm) strips. I use acetone glue to attach the strips to strengthen the arm which has broken on me a couple of times as…[Read more]

    • aaron did you print he foreharm parts as one? i mean rob2&5 and 3&4?

    • That forearm as 1 unit looks great! I am getting ready to begin printing my arms. I was wondering what a solid piece would look like.

    • Can you tell me where to get the stl for the one unit forearm? mine look a bit stupid as 2 pieces and will probably break

  • About 90% done with the right hand. Just need to wire up the board and program in Arduino. This last bit I am leaving to some STEM kids in middle school

  • I currently working as a robotics mentor for a local Middle School. The class has been focusing on VEX robotics competitions. With the competitions being over for most, I am looking to introduce them to the InMoov robot. The class has experience with mechanical builds, motors and servos, 3D printing, Arduino and CAD, which all fit in with the…[Read more]
