First of all, the robot must be very smart and be able to memorize what people have taught it. I just need to install a memory card in the robot's brain on the line, people said to him, a sentence can not be forgotten; I also gave him the design of a human-like "nose", can be smelled out of the aroma of the meal; he also has ten flexible fingers, so that you can wash vegetables, cut meat and so on ... ... ... so that mom and grandma can no longer work hard every day, and I can still eat the same delicious meals.
But if there is no electricity, the robot is to "strike", which I have thought of: in his back to install a solar charging device can be, every day, the robot to do the first thing is to go outdoors to "sunshine" --- charging. The first thing the robot does every day is to go outdoors to "bask in the sun" - to recharge. He'll also store the excess power for when the sun doesn't shine.
In order not to make the ideal become a pipe dream, I will double my efforts in the future study, only to master a wealth of knowledge, it is possible to realize my ideal.
