3.2 Mandatory Activities
Prior to being permitted to operate in any competition areas (on land or in water), each autonomous system must pass basic functionality and safety checks. These include verification that the systems meet vehicle requirements as specified in Section 5.3 System Requirements, as well as demonstration of the operation of all safety systems.
Vehicles are weighed before each scoring run. Teams transport the vehicle on their cart to the scale for weight measurement.
Any system operating in autonomy courses must report status and other required data via the RoboCommand system as specified in Section 3.4 Communications Protocol.
3.2.1 Static Safety Inspection
Prior to deploying at the competition, all systems must meet all safety requirements and pass a safety inspection, as outlined in 5.2 Safety Requirements. Any system that is deemed unsafe may be disqualified. At a minimum, the following requirements are checked:
Emergency Stop System (location of switches, on-board and remote functionality).
Tow points and tow line are installed and clearly marked (forward/aft).
Lift points are clearly marked and lifting harness is sufficient.
Safety requirements for propellors, including propeller guards.
All components or subsystems are properly secured.
Mount points and compatibility to carry emergency recovery light.
Cart meets published transport requirements.
More details on safety and system requirements are available in 5.2 Safety Requirements and 5.3 System Requirements.
USV Functionality and Safety Checks
Teams must demonstrate that each USV adheres to the system requirements outlined in 5.3.1 USV Requirements and pass the static safety inspection and weight measurement.
UUV Functionality and Safety
Teams must demonstrate that each UUV adheres to the system requirements outlined in 5.3.2 UUV Requirements and pass the static safety inspection and weight measurement.
UAV Functionality and Safety
The Civil Aviation Authority of Singapore (CAAS) serves as Singapore's national aviation authority, responsible for safety and air traffic management. Teams must meet all requirements mandated by the CAAS for their UAV. Compliance with CAAS regulations will be collected in the UAV Proof of Readiness, required of teams prior to competition.
UAV Airworthiness Safety Inspection
Prior to being cleared for flight, the UAV must pass the airworthiness safety inspection. At a minimum, the following requirements will be checked:
Meets the limitations for size and weight.
Safety issues related to, but not limited to, propellers, motor mounts, general airframe and wiring integrity, battery security, and battery capacity checks.
All sub-systems are properly secured.
Autonomous flight control disconnected to enable manual flight control mode.
Mount points and compatibility to carry emergency recovery light.
More details on system requirements are available in Section 5.3.3 UAV Requirements.
3.2.2 Weight Measurement
Systems are weighed at the start of competition to ensure compliance with the system requirements. Teams transport the vehicle on their cart to the scale (similar to a veterinary scale, available at scaleline.com) for weight measurement. The stable scale reading weight is recorded.
During scored runs, the systems must be re-weighed every time it is launched into the water. If the system stays in the water between scored runs, teams may forgo the weight test a second time. However, if a team is observed to be switching significant components or making modifications on their boat, the team may be asked for a new measurement.
