Hello Echo, being sighted, you give me some new food for thought, as I try to imagine trying to do these things, even without my glasses I would have a very hard time so I can imagine having no sight.. I can answer the first one about the battery. When you get your pleo rb, it will have a battery that needs to be charged anywhere from 2-3 hrs, but to be on the safe side since you have no way of knowing if the light has turned green, I would just time it for 3 hrs to be safe and you should have no trouble. Also do the same thing for playing with Pleo.
Take notice of what time it is each day when you begin playing with Pleo, and you can set a clock for example, and when the clock goes off, or Pleo stops and snoozes, you will know how much time has gone by. Pleo also will let you know when it shuts itself off by the number of beeps, Two beeps means that you have shut pleo off manually, ( pushing the on off button on the back side of the belly) Three beeps means the battery is low or needs to be recharged, As for the clock setting battery which goes into the foot, if it is put in wrong or there is a problem it will beep continuously and pleo will not operate correctly till it is fixed.
To check the DNA of your pLeo Rb, you can use a free downloadable program here on the forums called Probe RB. First you play with Pleo Rb for a short time, I did this the other day with my new baby rb and only for about 15 minutes and it was a fresh charged battery, Then I turned pleo off normally. I then inserted the micro sd card which has Probe Rb on it in the belly slot of Pleo, Then put the battery back in and turn pleo on with pleo lying on it's side. Probe rb will begin talking to you in a woman's voice which is nice, because she will tell you what to do, pushing her chin for instructions she tells you which foot to push for DNA , which foot to get Pleos health report, etc. It is a very nice and good program,
I am going to let someone else answer the rest of the questions, I think you will find a lot of these are not as hard as you may think, Talon who is also blind has managed well and she has four Pleos with two of them being RB. Good questions.! RWM

Also there are videos explaining most of these and listening to them will help.
