1. Examples of robots or solar energy benefiting mankind 2. A typical example of satellite playing an important role in Wenchuan earthquake relief.

Solar water heater, solar car, solar cell, solar power generation. . .

Solar energy helps human aircraft provide power. . . . . .

Robot:

Robot mine-sweeping, mechanical arm of automobile factory, robot for deep-sea scientific research, robot can be nanny (Japanese robot is the best). . .

Satellite:

Shoot satellite maps and provide real-time geographic information data (such as rivers, meteorology, topography, etc.). ) and weather forecast. . . .

During the earthquake, the satellite real-time map can be used to detect the dammed lake (that dammed lake, the fierce one at that time, Tangjiashan dammed lake, which was seen through satellite and saved many lives); Assess the losses caused by the earthquake; Observe the terrain, road conditions and traffic conditions at the scene in order to make a suitable rescue plan. After the disaster, it can also be used for the location of new relocation sites, and so on. . . . Too many. . .

If you don't understand, ask me. . . I used to study geography. . . Know a thing or two . I hope it helps you. . .
