Hi everyone, first of all im spanish so im sorry if my english have a lot of mistakes.
I just bought my RN-1 last friday and im a bit lost, i have a few questions:
1º - Is there any way of not having to set the zero points everytime i load a new routine to the RN? I mean, it was working perfect when i just turn it on the first time, then i loaded the kung fu routine i found here (thanks for that, was amazing!) but it started with the RN bended, then i set the zero point again and it worked perfect but when i loaded the standar one it happened again.
2º - What is the funtion of the different sensors, like accelerometer, inclinometer, etc.
3º - Is because i need one of them why the RN dont move as smooth as i saw in some of ur videos?
Thank u very much in advance!

Hi Answer,
Welcome to the group..
The Original template file does not have the zero settings built in. When you save then into the template file, they can then be copied and pasted into any other template file. Matt Bauers Kung Fu template has the zero settings for his robot, so you need to replace these zero settings with your own. Do this with any other template file you use.
Parts can be copied from RoboBasic and pasted into any text editor such as Wordpad. They can then be copied and pasted into another template. I keep a text file with just the zero settings for this purpose.
Accelerometers help the robot determine if it has fallen over.
Gyros help with stability.
Sonar... distance to an object.
There is a lot of information here in the many pages of postings, and the people are very friendly.
Have fun with the RN-1

Hi Again,
What to add or not add to the robot is really more a question of what you want to do with it. One of the most common additions in a gyro or two. I added 2, then disconnected one of them. At the moment one is enough for me.
Some people add a lot of stuff.. some do not. Look at the amazing things that DirtyRoboto is doing with a standard out of the box RN-1.
I have gyros, a Bluetooth module, battery monitor, and homemade grippers. I plan on adding an accelerometer sometime.
You can do a lot with it the way it is though.
Good Luck
Gary

Hi Humanoido,
I did the typical 2 gyro front-back and side-side thing. The F-B wasn't working as well as I thought it should, so I changed the electronics, replacing the F-B with the S-S. It works better now. I think there is something wrong with the other one.
They are mounted on the shoulders, and I use just the leg servos. Actually, for a lot of stuff, i turn all gyro activity off.
Gary
Edit: They are GWS PG-03's.

Hi Humanoido,
Quite honestly, I have done very little with walk cycles up to now. I need to get it down soon though. I also have troubles with turning and I really need to get that figured out as well.
I turned the gyros off because they weren't really helping with what I was doing at the time. Something else I found curious, is that with my toss sequence, it works better if I turn the PTP off, then back on after the toss. It was slowing some of the servos down.

Thanks Gary for the tip. Since timing with RN can be so important, it's good to know the elements that affect it. Setting the servo speed is only one factor.
My RN is also "turning-challenged." I believe it will need another round of tuning and shoe replacement. There are always slight differences in the forces placed on the left foot compared to the right. My ceramic floor is a big factor too. I think a natural wood floor is more ideal.
I may reprogram the turning. In one video, I believe it was the Brat biped robot, it took a much larger stance for turning, and it seemed to work very well. (ok, found the video, click below)
