Categories: Robosapien V1 & V2
Question: When using my v2 today I could hear faint but audible cracking sounds. Does that mean the plastic gears are giving out?
Problem: THis problem just arose today and so far has only happened on the caraty (if that is how you spell it) chop function. When I push shift3+c he does his caraty chop with his left hand (when he is facing you) just fine. When I push shift3+ x He leans back, puts his right arm out to the side, leans forward and brings his arm down but fails to turn to the left while he does it like he is supposed to. What is wierd is on the dance function and just using the right control stick he can turn to the left just fine. Thoughts? Possable solutions?

Madison WI, United StatesCan you listen while making his head turn to the right or left? From what I've seen, it is more likely to strip a gear on the head/hand mechanism. Otherwise, removing the torso shell may help you localize the sound better?

His head works just fine. His hands open and close as well. He can do every action except that one carate chop. It's like it forgot how to move his arm down and to the left at the same time. ANyway, if it were a striped gear, wouldn't he not be able to turn at all? He can still turn, just not when doing that action.

United StatesHow fresh are the batteries?
Is it possible that it's the combination of motors running for the coordinated movement that are causing a low voltage problem?

I want to post a video of the problem but I do not have a you tube account. Nor do i want to make one. Does anyone have a youtube account that would like to help my by me emailing them the video and then they post it? Thanks.

Mr. Scott/ Sorry, forgot to address your first question about the battaries. THe battaries are fairly old but they are heavy duty rechargables and he walks like he did when I first put them in. I can tell when the battaries get low becasue he starts to have a hard time with carpet.
here is the faulty karate chop
and here are the other motions that appear normal...
I just found something else out. I put him in puppet mode. I turned his left arm out. I turned the left arm back down while rotating the torso. WHen he repeated this he did just fine. I did the same thing with the other arm and found that he seems incapable of perating his rite arm and torso at the same time. Kinda like there is a short. Milw said he would post my videos soon so you all will see what i am talking about.

Melbourne, AustraliaCracking quite often means that a joint is attempting to move past its stops. The first thing you should do is locate the source of the cracking.
Nocternal, THe cracking sound happens when the arm, head, torso (you name it) is in the middle of moving. I guess it mite be that but I dout it. It is also one of those things that just appeared.

United StatesThe "clacking" sound is often gears slipping. Nocturnal's suggestion that it's at the end of a joint range is one explanation.
Another explanation is that some teeth have been sheered off of a plastic gear and it's slipping in the middle of its range. It could be the extra stress of the coordinated movement (lots of pieces moving about) is enough to cause the slippage.

OH. THanks MrScott. Does anyone have ideas as to whey my v2 moves fine when moving the torso alone but fails to turn the torso during certain actions?

Melbourne, AustraliaGear slippage is possible, I just don't think its likely. The only gear with a proven propensity to strip is the rack an pinion gear for the hands, and that usually manifests as the head / hands snapping closed as they head towards the outer most positions. Far more likely is a damaged sensors, or faulty wiring. Which could manifest as a joint that does not move quite right, and tends to try and move past its stops.
Grab your remote, and your manual, try moving each joint (I mean every joint you can) to as far as it will go in each direction with the remote (not manually, not using a puppet program), and then back to center. Watch for joints that don't seem to be moving right, or make loud clicking sounds.
You may also want to open up his chest and make sure that all the plugs are seated correctly and that when he moves, nothing is putting undue strain on the wiring.
Nocturnal, thanks for the help. I have already moved everything separately. As of now, only when his head is moving from left to rite and rite to left does the cracking sound occure and it only occurs when the head is rite around the center (he is lookiing forward.) The hands are not snapping closed though and other than the cracking noises, everything moves just fine when moving by itself. After messing with the v2 I have discovered it is completely unable to move its rite am and torso to the left at the same time. IF the torso and rite arm are trying to move at the same time then the arm usualy wins. I am going to go out on a limb here and guess that for whatever reason there is a short somewhere in which case i can do nothing and the warrenty is long gone.

Madison WI, United StatesWell, I think what you have to do next is open up the torso and take a look at the wiring and the gears. It's possible your v2 has the insulation rot- you might notice bits of colored insulation falling out of him if you shake him a bit. Also then you could look at the gears and see if you can localize the sound better. It's pretty easy to take the shell apart, just need a medium phillips head screwdriver that fits the screws. (a too small screwdrive can strip the head if you aren't careful).
Are you willing to open him up?

I will open him up as soon as I manage to get a screwdriver that fits. That mite take a while becasue the screws are already striped but i think som super glue and a screw driver mite get them out.
