When I create a frame in auto positioner, sometimes it goes haywire and moves uncontrollably. I have tried starting over a few times with new profiles to no avail. All the servos have been fine tuned, and can happen in any frame. Any ideas why?
Upgrade to ARC Pro
ARC Early Access will give you immediate updates and new features needed to unleash your robot's potential!
you can try with one movement excample head turn left or right,
and set the delay higher some75
also i dont see the calibration pose.arms side ways
does it have an init ?
all servo set to normal 90 degree,so when he connect he chould stand with his ,
arms side ways.if you dont have a init page ,the robot has no starting point.
Are the servos getting their power from a regulator or direct from a battery?
I'm not certain how those little servos react with more or less power. So it's hard to say if it's too much power, or not enough power. Also, I suspect the two batteries are sharing a common ground?
Lastly, you can connect a 5v to the EZ-B as well and only use one battery instead of two. Simply disable the battery monitor in your project. The settings to disable it are in the Connection Control. Depending on your version of the ez-b, there may also be a "disable battery monitor" setting in the web server. That option merely disables the battery monitor on boot-up, but you will still need to disable it in the project.
It just occurred to me that the "spaz" might be due to servo positioning. Those servos may have a different servo band limit than normal - which is quite common with hobby servos. Perhaps the positions that the servos are moving into is causing them to spaz between pulse widths.
Although, i'm putting my bet on power related.
- Check the EZ-B web server to see if you have the "Disable BAttery Monitor" option and it will stop saying "my battery is low" when it powers up. You will still need to disable the monitor in ARC
I'm leaning toward the 5v bec 8a overheating or causing some problems. 8amps is very much for servos - they can draw up to 15-20 amps (depending on the model and weight). This is why high discharge batteries are important with robotics. The ez-robot batteries are 25c
