I never came around to actually mount Johnnys head to my #R8-D8 - a distant relative of R2-D2 - it's possible to even motorize it later, but for now it's just fixed and transportation is way easier now! Currently in revision is a 3D printed case for the vl53l0x, to protect the module that replaces the interactive ultrasonic module. What other robot could I throw in there to mash up?
