Remote controller for sale?

[linzoid]

Hi all,

I am looking to buy a remote controller, serial cable and software CD (although this item is not totally necessary) for a Robonova 1, does anyone have a spare they would like to get rid of??

Thanks

That's going to be hard to find - if someone has an RN-1, it's not likely they'll want to part with either the remote or the serial cable. I have enough parts for 4, but I still only have two remotes, and only one serial cable. The software is still downloadable, there are a few links around here to those.

Hi,

Thanks for getting back to me. After seeing a number of RN 1's on sale on Ebay recently, I thought it would be easier to find the missing components I am looking for than it has been, but I will keep on looking in the short term.

One question, when I switch on my RN, I have to steady him while he extends both legs otherwise he falls over, is this the norm or should the robot stand up unaided from a squatting position?

It seems that his left leg is slower than the right to extend, can I assume one or more of the servos area bit dodgy?

Where do the like of yourself and other RN1 owners get spares from these days?

You can make your own serial cable. All the information and resources you need can be found here:

This includes everything useful from the CD. I've been collecting this in an archive for a while now.

Can't help with the remote though, sorry.

He should stand up straight on his own. Double check the trims, make sure the legs are a mirror of each other and that the feet are flat. Mine will try to vault himself forward if I make him move from kneeling to stand on a low battery - might not be the servos. I'd test them one at a time with the Robonova sofware, making sure all the servos behave similarly with no load on them. Could be a weak battery. Even on a 5v PC supply (more than enough amps), moving to standing at a faster speed makes him a bit weak in the knees. He really needs 6v, and a weak pack won't hold up 6v as the amps increase (do more faster, etc).

I bought some parts to make new battery packs last night, I'll post back about 'em once they're built - posted about them here: http://robosavvy.com/forum/viewtopic.php?p=38293

Spare Robonova's. And extra servos. I bought some from http://www.servocity.com, but they don't stock them anymore.

I ended up calling Hitec about the Karbonite gear in the HSR-5498SG (I have a bunch of these, they're an upgrade to the HSR-8498HB), they pointed me to an equivalent gear set for another servo they sell, and I bought a bunch of 'em. They might be able to do the same for the HSR-8498HB, I didn't ask.

A word of caution - be careful about the grease you use if you end up greasing a servo. I use the Hitec stuff. The reason I say this is, I bought a RN-1 off Ebay, and someone used what looks like petroleum jelly inside, and that servo was completely fried.

It's getting increasingly difficult to find parts for these guys. It's a shame Hitec decided to quit making them.

Closest similar competitor (my opinion) is the Bioloid GP, but he costs more than I really want to pay. There is a 'bot out there from minirobot.kr (I believe they did the original RN-1), but it's hard to say how well it is supported, haven't even seen an owner of one post here.

With the rework I've been doing on my main bot, I can't really call him an RN-1 anymore. That said, I've been wondering how well the Robotis AX-12 would adapt to the RN-1's body style / configuration and what it would take to build up a "Robotis Robonova"... I think that'd be a good seller.

As much as plastic bots (ex, Bioloid, etc) are very popular, I just don't find myself interested in them...
