no you wont die.
This is one of my main bots and I run it 24/7 on my lvl 94 with no armour. I maybe die once every 24 hours.
Just wear 3 things and you will be all good, the bot just runs back to the LRC after you die and keeps mining.
With a Dragon Pickaxe and 99 mining, I make about 200k/hour there.
Good luck!
