I recently watched a bucket truck and two city maintenance trucks, along with 6 workers, changing a street lamp in my city. Took them over two hours, and they blocked a lane of traffic in a very busy shopping district. Seemed like a tremendous waste of man power and equipment, when all that would be needed is a pole climbing bot with enough dexterity to open the lamp housing and replace the bulb. I'm thinking about building a prototype of some sort that could be scaled up to manage this task.
