Frequently
asked questions

The A2 can be controlled via remote controller and mobile app. It also features a dual LiDAR system, allowing users to program routes and enable autonomous navigation in structured environments.

Yes, but with caution. While it is capable of operating around people, its size and strength require careful handling and controlled operation in crowded spaces.

No. The A2 can operate offline without an internet connection. Users can connect directly via Bluetooth.

The A2 offers up to 5 hours of battery life depending on usage conditions and payload, supported by a dual-battery system that enables longer operation in field environments.

The A2 enhances efficiency by:
– Reducing reliance on human labor in hazardous or physically demanding environments
– Operating in extreme conditions where humans may be at risk
– Providing consistent, stable performance across long durations

This makes it especially valuable for outdoor industrial workflows and heavy-duty operations.

Yes. The A2 models are open-source platform, allowing integration with enterprise systems, robotics frameworks, and custom software environments.
