How to Use a Crawler Robot

A crawler robot uses a combination of mechanical, electronic, and software systems to navigate and perform tasks in various environments, the majority of which are inaccessible or hazardous for humans.


Initially, the inspection crawler is deployed into the area you want to inspect, where its movement is controlled remotely. Equipped with cameras and sensors, it captures real-time data or images of its surroundings remotely while the inspector stands at a safe distance.

As inspection data is transmitted back to the operator they analyze the condition of the area being inspected, identifying potential issues and navigating the crawler to specific locations for closer examination. Inspection data is also being recorded, and can be reviewed after the crawler returns for closer analysis.

This short step-by-step covers how inspectors use crawlers in their work:

  • Deployment. The robotic crawler is placed in the starting location.
  • Remote control. Operators guide the crawler robot using remote controls, often from a safe distance.
  • Data collection. Cameras and sensors on the crawler robot gather visual and environmental data.
  • Transmission. Data is sent back to the operator for analysis.
  • Analysis. The operator assesses the data to make informed decisions or take further action, both live in the field and after the data is collected.

After analyzing the data from the crawler, operators can make decisions regarding maintenance, safety measures, or further inspection needs, ensuring efficient management of infrastructure, facilities, or other areas of interest.

Customizing Your Crawler Robot for Specific Tasks

Customizing your robotic crawler is key to maximizing its utility and efficiency in various inspection environments.

By carefully selecting and integrating these customizable components, your robotic crawler can be adapted to perform a wide range of tasks, from underwater inspections to confined space navigation, making it a versatile tool in your inspection toolkit.

Here’s how different components can be tailored to meet your unique needs:

  • Camera systems. Choose from standard to high-definition cameras based on the level of detail required for your inspections. Advanced cameras can offer panoramic views or zoom capabilities for close-up inspections.
  • Manipulator arms. Add manipulator arms for tasks that require interaction with the environment, such as picking up objects or performing minor repairs.
  • Sensors and detectors. Equip your crawler with various sensors to detect different types of gas, measure radiation levels, or assess structural integrity through ultrasonic testing.
  • Lighting options. Use adjustable lighting systems to ensure clear visibility in dark or murky conditions, crucial for underwater or enclosed space inspections.
  • Track materials. Select tracks made from materials like rubber for general use or metal for added durability in harsh environments. The right track material ensures optimal traction and maneuverability—keep reading for more on track materials.

Choosing the Right Tracks for Your Inspection Crawler

Choosing the right tracks for your robotic crawler is crucial for optimizing its performance across different terrains and environments.
