This chapter presents the conclusions of the book and future directions of electric power robots. The conclusions are related to the development of condenser cleaning mobile manipulator robots, transmission line robot manipulators, and aerial manipulator robots with applications. Faced challenges involve novel environmental perception, decisional autonomy and planning, intelligent control, human-robot interaction, mechanism design, and related technologies. Future directions of electric power robots are fully autonomous with multifunctional operation modes, collaborative autonomy, and novel morphology. Finally, the four major driving forces are summarized for accelerating the applications of electric power robots.
