(nearly) Finished Robotic Arm: When i tried to attach the hand on to the ends links, there were things misaligned in the assembly and I couldn’t attach the end. I spent a miserable amount of time going back trying to find the mistake, finding multiple areas where the measurements were of by fractions of a millimeter. I fixed some things in the end, and it works now, but some of the constraints are still finicky. I don’t think this will matter when its put together; it is just me being picky. One reason why this may have happened was because of my choice to use imperial measurements with parts that used metric measurements, as well as bad 3D modeling. This was a good learning experience though. I am mostly done with the upper assembly, and the only major thing now is that I just have to create the lower portion which will hold all the electronics.
