Fourth and final in a set of doodles our friend randy ( https://twitter.com/Randy_Magpie ) drew as a gift recently. A later step in the process, after at least some of sys' arms have gone through the diagnostic and examination stage and come out clean or been repaired, is working bits of the torso. In this case, there's clearly something bothering us about that left head's sensor equipment, but it's an easy desolder and replace job.

Randy got a detail here correct without even knowing about it that we find funny - that chassis tends to use its lower arms for strength/steadiness related tasks, and the upper for tasks that require more fine motor control... and that's exactly what's going on here with that head holding and soldering.
