Applications Mars Rovers of NASA Twin Mars Rovers Mars Pathfinder Mission - - - - Unit Recent developments in physics Materials used to make robots For robots, aluminum and steel are the most common metals. Aluminum is a sofer metal and is therefore easier to work with, but steel is several times stronger.
In any case, because of the inherent strength of metal, robot bodies are made using sheet, bar, rod, channel, and other shapes. . Te robots are much cheaper than humans. .
Robots never get tired like humans. It can work for x . Hence absenteeism in work place can be reduced. .
Robots are more precise and error free in performing the task. . Stronger and faster than humans. .
Robots can work in extreme environmental conditions: extreme hot or cold, space or underwater. In dangerous situations like bomb detection and bomb deactivation. . In warfare, robots can save human lives.
. Robots are significantly used in handling materials in chemical industries especially in nuclear plants which can lead to health hazards in humans. . Robots have no sense of emotions or conscience.
. Tey lack empathy and hence create an emotionless workplace. . If ultimately robots would do all the work, and the humans will just sit and monitor them, health hazards will increase rapidly.
. Unemployment problem will increase. . Robots can perform defined tasks and cannot handle unexpected situations .
Te robots are well programmed to do a job and if a small thing goes wrong it ends up in a big loss to the company. . If a robot malfunctions, it takes time to identify the problem, rectify it, and even reprogram if necessary. Tis process requires significant time.
. Humans cannot be replaced by robots in decision making. . Till the robot reaches the level of human intelligence, the humans in work place will exit.
