H2H for Manoi

[Orac]

Hi, I have been using H2H Type 3J 2006/10/06 and am having trouble setting the Home position well enough to run even the simple sample files without falling over.

Should I be using the version that came on the CD?

Thanks

I've used both H2H and H2HJ. The home position is very critical and can be finicky.

I could get it to walk one way along the table but it wouldnt walk the other. Then someone suggested was the table level?

Indeed it wasnt so after leveling and adjusting home again it will walk both ways. It is a very fine adjustment

Both versions of the software treat the Home position identically, so most likely that isn't the problem.

Which procedure are you following to setup the Home position? The setup procedure on the AT01 website seems to work okay.

Good way to check and see if your Home position is correct is to create a Link that increments the leg servos evenly - say by 10 - to smoothly lower the body. If the home position is correct, then the body will move straight down vertically. If it's off, then the body will tilt in one direction or another.

Many thanks, I have tested him on all the RCB english versions of the files posted here, all bar a couple are now working fine.

The faster ones are still causing him to topple over but that will just be fine tuning.

Are there any other Manoi RCB files posted anywhere that anyone has come across?

Thanks

It takes a little practice, and experimentation, before you get the hang of it. The fact that you're working on the robot closeup tends to distort perspectives, so you think you have something lined up when really it's off a bit. The same thing happens when you try to hang a picture on a wall.

Sighting along different features seems to help. For example, there are mounting holes on the legs that you can sight through to make sure that the two legs are parallel.

Also, keep in mind that one adjustment often affects others. Some builders start any alignments from the body - say the hips - and then work outward, one set of servos at a time. Others work from the foot/soles upward.

Another significant factor is the battery weight and location. The robot is 1/5 scale, so the battery is a significant part of the physical loading, and all the canned routines assume it's onboard, even if you're using an external power supply and don't have the battery plugged in.

The most complete source for reliable RCB files is Kyosho AT01 motion download page since Shiroma tests any contributed motion file before it gets posted. There are also a few AT01 soccer motions - different kicks - that were contributed to the botconnect.com website.

Many thanks, you are correct, I have removed the battery, can't believe I missed that one

Hence why it has a tendancy to topple backwards

I'll have a look at the two sites a bit later and put the battery back in !!

Don't feel bad, you're not the first one to fall into that trap.
