Bear Arms and arm servo mount chassis section for Chip-E Robot

thingiverse

I've always been a passionate advocate for robot rights, particularly the right to bear arms! Simply existing as an armless biped is utterly unbearable, and I figure entering this challenge is the bare minimum I can do to correct this deficiency. This project is a set of torso servo mounts and lovably cute bear arms for your Chip-E robot. They are designed to insert between the lower battery compartment and the plate that the head mounts to. They use a pair of servos identical to those used in the legs, and are affixed to the chassis in the same manner. The arms are designed to screw onto servo horns, although I don't have a set to test with, so some adjustment or drilling of a center hole may be required. I simply imported the base STL files for the Chip-E, then extruded a series of mid sections, aiming for 3D printability without support. Using the dimensions from the leg mount, I was able to replicate that geometry and provide adequate space for two servos. Future expansion potential exists for adding a third rotational head servo. Assembly: To use these parts, print them out and then insert them into your Chip-E robot using the stock hardware mount to the battery compartment, along with some M3 bolts to connect the center section to the upper plate and standoffs. I recommend gluing or taping the bolts in place for stability. The servos feed in from the back. Then plug the servos in and make them do stuff. As I don't actually own one of these robots yet, I'm uncertain about the specifics of the programming required. New abilities and skills this modification confers: * Bear hugs * Ability to wave your hands in the air like you just don't care * Showing attendance in school * Asking questions or volunteering for things * Flipping off traffic (note: flippoffarm.STL was deemed too powerful for use by mortal robots, and has been omitted from this project) * Showing excitement on roller coasters * Fencing and other acts of swordsmanship * The ability to bear arms with bear arms, which are also bare arms unless they're bearing weapons, then they'd only be barely bare * Theoretical ability to stir things and eat soup * Ability to play the piano (note: talent to play the piano not included) * The ability to take the arms off and hide them while entering an illicit location where arms are forbidden (arms smuggling) * Professional football career * That fight move where you spin your arms around a lot and hope the bad guy goes away * Golfing! And many more! (also, the ability to later mount additional microservos and make an arm with articulation and whatnot.) Video describing the modification: https://youtu.be/Af0-XlamO5s
