It is possible for a video with a robot voice to go viral on YouTube Shorts, but it would depend on the quality and content of the video. If the video is engaging and entertaining, and if it resonates with viewers, it may be able to attract a large audience and become popular. However, the use of a robot voice may also turn some viewers off, so it's important to consider how the voice will affect the overall appeal of the video.
To increase the chances of your video going viral, you can try to make it as unique and interesting as possible, and promote it through social media and other channels. You can also try to collaborate with other creators or influencers to reach a wider audience. Ultimately, the success of a video on YouTube Shorts will depend on many factors, and there is no guaranteed formula for going viral.
