What are the key factors in selecting sensors for a mobile robot?

Asked on Dec 18, 2025

Answer

Selecting sensors for a mobile robot involves considering factors that influence the robot's ability to perceive its environment and perform tasks effectively. These factors include the robot's operational environment, required sensing modalities, and integration with existing systems like ROS.

Example Concept: When selecting sensors for a mobile robot, consider the environment (indoor vs. outdoor), required precision, and range. For navigation, LIDAR and cameras are common for mapping and obstacle detection, while IMUs provide orientation data. Sensor fusion techniques can combine data from multiple sensors to enhance accuracy and reliability. Integration with frameworks like ROS can facilitate data processing and control.

Additional Comment:

Consider power consumption and weight, as these affect the robot's battery life and mobility.
Evaluate sensor robustness against environmental factors like dust, water, and temperature variations.
Ensure compatibility with the robot's processing capabilities and communication interfaces.
Assess the cost-effectiveness of the sensor in relation to the robot's budget and mission requirements.
