I am getting a Robonova for $500 (NZ dollars). He has had it sitting awhile, hardly used, so is selling it.
These are not available is New Zealand and see they still sell for around $900 US.
Will be to replace the battery as the guy says lasts around 30 mins,yet read you should get around 1 hour.
My first addon will be the speach recognition, then looking at gripping hands.
I know with gripping hands you need to extra servos which is no problem, but how do you get Robonova to see the other 2 Servo's?
At the moment Robobasic makes no sense to me at all. Mind you have not got Robonova yet to have a play.
So how do you get Robonova to recognise it has movable grippers?
Mind you to get the grippers will be some time off due to the expense. I understand the servos are not cheap to buy.
With postage to NZ, etc adds up.
But the speech recogniton is a cheap upgrade and looks really handy to have and understand it comes with the basic template, etc to get you going, but grippers as a kit may not?

Battery life depends on how much "work" you make the servos do when running your RN-1. 30 minutes of nonstop action isn't out of the question, depending on what you have him do. Also, battery conditioning, charging it up, running it down, and recharging, can produce better results than charging, letting sit for a few weeks, then running, then recharging, etc.
The gripper kit that Hitec sells comes WITH servos (I have found the Hitec gripper kit WITH servos cheaper than buying just two servos!!!).
The controller for the RN-1 supports more than the base 16 servos, but I can't recall if the maximum is 24 or 32, I think it's in the pages here on Robosavvy somewhere (MRC 3024 controller). To actually make the grippers work, you will need to write your own program using the Robonova software (or C, if you go that route, also articles on the Robonova pages here). The controller has no "awareness" of additional servos, you have to tell it what you want to do with them, and when.
RoboBASIC is fairly straightforward, you can learn a lot just by examining the base program and referring to the RoboBASIC manual for what certain instructions do.
I don't know much about the speech kit, but the grippers don't come with any sort of template, you have to program them to move. This can be as simple as adding some moves to one of the basic template routines.
