Moving in power off position

my robot is trying to work/move while in the power off position. I moved it to S and F, but none of the lights changed. Last week, I couldn’t get it to power on. So, I made sure it was charged. Then, it sat for almost two days with all the red bars showing in power off position. Here we are today, coming on (all by itself) in power off trying to move on the floor. What do I do? What’s wrong with it?
