Turns When Walking Forward

I have build six as the builder shows and ran the servos outside of the mounting joints to ensure everything was set correctly. Six tends to do two things, one of the servos seems to love to hum very loudly when the robot stops moving. Making to robot move once stops it for a while. I have taken the servos out of the mounts and reran the "all servo 90" and the issues remains. Second one is the robot will not stay straight with walking. It walks in a big circle. confused

@JFew, how big of a circle is he walking?

Because the robot walks with six legs (haha, six) there will be slight drag on each foot - causing him to turn slightly. I created the six walking routine about a year ago and it probably could use some work.

You can tweak it a bit and share with the community, because that's what we're all about:D

As for the hummmmmmmmmm of the servos - it's normal. Servos are not "motors" as they actually know their position. To keep position, the servos are actually moving back and forth real quick. This causes a hummmm noise. The stronger the servo, the louder the hummmmmmmmm.

This is why robots in movies also make a lot of noise:D

The circle is about 3ft wide

Have you actually checked to see if all the servos are working correctly? I mean testing them one at a time for full travel... Also check to make sure nothing is binding in the joints or any servo cables getting stuck...

@jfew, when Six is in the standing position, are all of his servos at 90 degrees?

yes the servos are at 90. I have checked and found nothing binding in the joints or any servo cables getting stuck. The servos are able to move freely.

Can you upload a video of Six walking? Can you hold him in your palm and watch his legs move... maybe you can spot the gimpy (for the lack of a better term:) ) leg or two? If there is any I mean...

I can try to upload one. I will attempt to make one now and upload when done.
