## Use Cases

The Robot Dog is a programmable robot, its base function is to maneuver/navigate environments.

Basic manual operation is done via remote control through an app or the physical remote, along with voice commands.

Further functions can be achieved through programming the Robot with further attachments and equipment. As these functions get developed through Research and Teaching, they will become available for use.

### Navigation and exploration&#x20;

Autonomous navigation: Equipped with 4D LIDAR and obstacle avoidance for autonomous movement and terrain mapping.

Terrain exploration: Suitable for navigating and exploring controlled environments.

### Surveillance and inspection&#x20;

Remote monitoring: Real-time image transmission allows for surveillance or inspection in hard-to-reach or unsafe areas.

Inspection tasks: Useful for inspecting industrial or confined areas autonomously.

### Logistics and Assistance&#x20;

Lightweight object transportation: Can carry or move lightweight items, especially when paired with the D1 Servo Arm.

Routine assistance: Assists in controlled tasks such as fetching or organising objects in structured environments.
