Preparing a Compliant Power Cutoff for the 45th ROBO-ONE
A version-specific checklist for choosing a permitted cutoff and arranging a removable battery connector under the revised Section 5.3.
To meet the revised 45th ROBO-ONE requirement, install a physical, direct cutoff between the battery and the robot, using either a mechanical switch or direct connector removal. The cutoff must allow the robot’s power to be disconnected immediately and safely.
Do not make a MOSFET, meaning a semiconductor switch, or a relay the sole means of isolation. The revision notice says systems relying only on either component for indirect power control or interruption are not permitted under the revised Section 5.3.
A battery connector may serve as the cutoff if it can be removed easily and safely from outside the robot. Secure it so impacts or vibration during competition cannot pull it out unintentionally, and keep the power cable inside the robot’s case rather than routing it outside. These checks give the builder the immediate physical disconnection specified by the revised rule.
