I have been working with Peter Moy refining the iPhone control for some time now. I think we have found the limit of this particular technology. We finally made a sucessful load in, up the ramps with it. I have been wanting to develop this feature for some time now, as the loading and unloading of Maria into the Mothership is very scary, and for good reason! I count my blessings each successful round. Up til now could only unload with the iPhone. gravity with a 5 ton vehicle can be useful!
Previously, we had power issues, and the valves needed adjustment. Here, after the adjustments, and in the last picture you can see Maria starting to spin off, going up the ramps. This was a wildly dangerous situation that I stopped and retried three times before saying “enough!” Not sure exactly what the problem was, mechanically. The final drives are likely worn and one is worse than the other. The key issue though, is the interface. The touch screen is not suitable for emergency control. I had to take my eyes of the Maria to make adjustments on the the iPhone for a moment. Meanwhile, mayhem was unfolding on the loading ramps. Fortunately, we have an abundance of “E” (Emergency) stops!
