OZAI autopilot is a vehicle that can used in multiple scenarios in an none-driver environment. We designed a quick-release construction for the cargo box and chassis, it can quickly replace different cargo boxes under simple operation to adapt to the various scenarios. In terms of safety, we focus on the protection of the outside world in autopilot driving scenarios because of its special working environment. Therefore, we created a bumper system based on a new energy absorbing system (HAS), which can collapse and absorb the hit energy and protecting the outside objects being struck.
