Electrical Engineering Project Idea - Power-Line Monitoring Robot

Here's a project idea for electrical engineering third and final year academic projects. Develop a power-line monitoring robot that 'hangs' to the power line itself and scouts across the line inspecting for various types of faults on the line. It may measure various parameters using sensors and you may even equip a mobile camera to stream all the information to the ground staff. Take a look at this discussion to get a better idea: Robot for power-line monitoring

Let's discuss what type of information can such a robot capture and how do you propose to track it?
