I have small scale 300sqm warehouse - incoming full pallets, outgoing mixed pallets. It is too small for industrial automation, but humanoid robot could be a good fit - unravel pallets, pick boxes, put boxes onto outgoing pallets and shrink wrap those.
it is very difficult to find good (as in "good condition") battery for a 5+ old gadget. even if you find original one - it could be expired and DoA. but more often you get "compatibles" which die in 3-6 months.
taskbar is very much related, it is an instance of explorer exe with some parameters, that makes it show as taskbar. Try killing explorer.exe in the task manager, when no other explorer windows is running.
