This would be interesting, but I still wouldn't bet on it right now, maybe if this would be something that would be recognized and be normalizes in the future then I would consider betting in it.
For me it isn't just a robot boxing match, it is also the skills of those who controls them and the creativity to those who manufactured the robots.
I will rather bet on battlebots I watch on dstv than bet on these lazy bots. One fell down and was even dancing, how am I supposed to bet on something I don't even know how they work or operate. What's their skill fighting, one have to know about the characters of each players before you can even have some confidence in them, like the battlebots that I said, I know some characters and I have watch some eposided on their tournament and knows the ones that has top the leaderboard in 2 years.
Not going to even lie, this things can be manipulated for real, the is high complaint of UFC fight been stage and people loss money, if this become the new face of Gambling, a day will come that fight will erupt in that stage because those bots aren't realistic at all.
