Smooth Walker like Manoi,KHR-2 etc

True enough it is certainly serving well as a hacking robot, and with all platforms there are tradeoffs. Guess I wish we had just a little more torque and resolution per servo. But that wont stop be from building some new parts.

Just my opinion, but the RN performs just the way it was designed to.

There are a lot of trade-offs. As you add more power and complexity you also increase the cost dramatically. Hitec wanted to keep the price down, and address a larger audience of customers.

OmniZero, Black Blade (the latest version of Black Seed), R-Blue, Dynamizer, etc. are all advanced designs that you couldn't commercialize and sell at a reasonable price. Even if you managed to get the component costs down, the robots are still way too complex for most potential customers, especially novices, to begin to understand and use.

The RN and other J-class kits are a great way for people to get started, learn the basics, start hacking and improving, and then move on to other more advanced designs they either buy or create by themselves.

My guess would be a lack of capable servos, if you watch the black seed, omnizero and a lot of the other big players, they seem to sink down and raise a little with each step, and I think they are using torque that the RN servos just cant provide (at least at 6v). You would be better with a double knee joint as that would increase speed of leg movement, but even then you are still limited by torque, and furthermore compliance is an issue. Also the controller seems a bit slow and cant have mutliple PTP moves running out of sync which is very sad... and the accelerometer cannot be put to good use in a walking gait either. There are a lot of issues that seem to be stoping the RN from performing the way it ought to be able to

I am still working on smooth steps that replicate a human.BUT, i simply cannot get RN to play ball.Is it a lack of processing power it cant be the servo resolution as that is more than up to the job.Even with gyros on/off he just wont take large fast steps.Do i need to be looking at changing the board or maybe something else ?????
