Characteristics of Robots
There are some essential characteristics that a robot must possess. These
characteristics define whether any machine is a robot or not. Some of the
characteristics of robots are as follows:
Characteristics
of Robots
Sense Movement Energy
Let us learn about these in detail.
Sense
Robots have some sensors that enable them to sense and create awareness about
their surroundings and act accordingly. Just like humans have sense organs, robots
may possess one or more sensors like:
• Light Sensors: work as eyes for robots
• Touch or Pressure Sensors: work as hands for robots
• Chemical Sensors: work as nose for robots
• Hearing and Sonar Sensors: work as ears for robots
Movement
A robot needs to be able to move around its environment. It may roll on wheels,
walk-on legs, etc. In the case of robots, the movement can be of the whole body or
just the arms. In humanoid robots, the entire body moves but for some industrial
robots, only their arms move and function.
Energy
To function or work, a robot needs power. It can work on solar power, electric
power, or can be battery operated. Which kind of energy will be best for the robot is
decided by the task it needs to perform. Heavy-duty robots that work in industries
may be electrically powered, whereas a robot on Mars may be solar-powered.
