By building man-like robots, the following can be improved:
During times of trouble (break-ins, thieves, etc.) our man-bots can support us. They should have firearms such as a pistol. Having melee weapons can be safer for the victim and the attacker.
When your home needs some special improvement, your man-bot can dust, sweep, clean, and improve your house. Dusters, vacuums and other utilities should be provided for the man-bot in order for better home improvement.
The man-bot can also help in education, being used as a calculator, computer, graphing chart, and more. It can get more jobs for people such as engineers, scientists, and many other jobs.
The man-bot can go from small and simple, to a great and helpful tool, also used for defense, education, and home improvement.
