Another approach is by using the power of foreshadowing. In the MC Chinese novel, drop hints about something extraordinary that is going to happen. This makes the readers anticipate and start to form an illusion in their heads about what that event might be. Maybe it's a grand battle or a magical transformation.
One factor that makes it excellent is the character growth, even if the Mc is OP from the start. Maybe they start as physically strong but lack emotional intelligence, and over time they develop in that aspect. Also, an engaging plot that challenges the OP Mc in different ways is crucial. If the Mc just breezes through everything without any real struggle, it gets boring. But if there are opponents or situations that make the Mc think and adapt, it's a great light novel.
Another aspect is prior knowledge or experience. In some light novels, the MC is reincarnated or transferred from another world. Like in 'Konosuba', Kazuma has knowledge from his previous life which he uses to his advantage in the new world, and this knowledge combined with his unique skills makes him overpowered in certain situations.

I'm not aware of a specific 'mc as robot light novel' to base similar recommendations on. But some general robot - themed light novels could be interesting.
