Mobile Quadruped Inspection Robot

Spot

Spot is Boston Dynamics' flagship commercial robot—a mobile quadruped roughly the size of a medium dog designed to navigate terrain where traditional wheeled or tracked robots cannot go. With four legs providing excellent traction and stability on uneven ground, stairs, and obstacles, Spot can walk across rocky terrain, climb stairs, and fit into tight industrial spaces while carrying sensors and payloads. The robot operates either under manual remote control or executes pre-programmed autonomous inspection routes, making it ideal for industrial monitoring, facility surveys, and hazardous area assessment where keeping people out of danger is critical.

Frequently Asked Questions

Spot's agile four-legged design allows it to access hazardous locations—confined spaces, unstable terrain, areas with toxic gases—that are unsafe for humans. The robot can be equipped with sensors for temperature, gases, or radiation, and its inspection routes can be executed autonomously or controlled remotely from a safe distance.

Payloads mount to a standardized rail system on Spot's back. Official Boston Dynamics payloads include compute modules, enhanced autonomy packages with lidar, thermal cameras, and communication kits. The system recognizes installed payloads and integrates them into the user interface and APIs.

Yes. Spot can execute pre-taught autonomous routes repeatedly with minimal human intervention. Operators can create and schedule missions through the Orbit software, allowing Spot to conduct inspections on a set schedule or triggered by events.

Spot uses onboard depth sensors and cameras to detect obstacles in real-time. Its perception system continuously scans the environment and adjusts the robot's path or stops to avoid collisions while walking at operational speeds.

In autonomous mode, Spot can return to its dock for automatic charging. In manual operation, the operator is alerted to battery status and can manually drive the robot back or swap the battery pack in roughly one minute.

Yes. Boston Dynamics provides APIs and Orbit integration with business systems via webhooks. Inspection data, thermal anomalies, and alerts can be automatically exported to maintenance management systems, work order platforms, or custom analytics pipelines.
