Thanks for the reply Limor!
I'm curious about the similarities in the Kondo and the Hitec. I'm wondering if the controller design was developed by a single supplier and then branded and packaged by Kondo and Hitec.
I'm excited about the RB1000 for a number of reasons.
The servo spec - 9.2kg/cm .11seconds/60deg rotation
- compare this to 7.4kg/cm .20s/60deg for Hitec
- and 10kg/cm .14s/60deg on the new Kondo KHR-2HV
Leg Rotation - It has 2 more degrees of freedom with leg rotation right out of the box. I've been watching a lot of videos and it seems like most of the good competition bots have a joint there. I know a lot of people have been talking about ways to do it with the other bots but it seems easier to start with it done out of the box.
The frame design - it was designed by Takeshi Maeda at Vstone. He has been one of the top RoboOne competitors since it started. You can see the similarity in how the motors are mounted in pairs on OmniZero (1 and 2) and RB1000. It's a pretty clever design trick as it lets you get more travel by moving the servo horn as far out as possible. Compare the lower leg length of the RB1000 to the Robonova-1 to see what I mean.
Price wise it's the same as the others here in Japan, the RB1000 is 102,900 yen or about 1000 us. The Robonova is going for 98,000 and KHR-2HV seems to be going for 104,571 (there's a couple models and I'm not sure what the differences are, wish I could read Japanese)
The KHR-2HV is using higher voltage motors so I think it's controller would not be compatible, but I imagine that the KHR-1 controller could be compatible with the Robonova-1 as you mentioned.
Really the only reason I haven't picked up a RB1000 yet is the lack of an english support community for it. It seems one might form in time given the right space. <hint, hint> As it stands now, I think it might be hard going for the first few months...
