This question is a sort of continuation of my previous question: Why would robots use verbal communication?. The answer here by @Mathias Foster about the robots organizing a revolution sparked some interesting tangents in my storyline. What if these robots were to organize a revolution?
Here's the background from the previous question:
Robots designed by humans independently work on clearing waste in high-radiation areas. They return to civilization once or twice a year to be inspected and restored to be able to continue working.
Robots are, of course, considered no more than cheap labor, although they have an advanced form of artificial intelligence with thought processes similar to ours.
If these robots are not great in number (no more than 50) and are not monitored due to high radio interference, can they organize an uprising against human officials in only a year?
Note that these workers have one year before their checkup and reset to 'factory condition', after which they will not remember any of their former plans.
The only materials they have available to them are those they use for clearing radioactive waste. This may include construction equipment, high power drills, jackhammers, etc.
These robots are slightly larger than a grown man: around 8 or nine feet tall. They are humanoid in shape, and have the ability to pick up large objects (concrete housings, steel beams, etc.) that may stand in their way of cleaning up a radioactive containment breach.
