In the FlyingRobot class, the initialization of self.coords should not be repeated after calling the super().init() method. The super class BaseRobot already initializes self.coords, so this line is unnecessary and could lead to confusion or errors.


def go_up(self, steps: int = 1) -> list[int]:
self.coords[2] += steps
return self.coords

def go_down(self, steps: int = 1) -> list[int]:
self.coords[2] -= steps
return self.coords

In the DeliveryDrone class, when initializing self.current_load, it might be a good idea to check if the current_load's weight does not exceed max_load_weight. This would ensure that the drone does not start with an overloaded cargo.


def hook_load(self, cargo: Cargo) -> None:
if self.current_load is None and cargo.weight <= self.max_load_weight:
self.current_load = cargo

def unhook_load(self) -> None:
self.current_load = None
