KHR-1HV owner haveing problem with servos, help requested

I am havening a problem getting the full range of motion out of the 2 shoulder servos. Also when I move the slider on the gui sometimes a couple of the other servos will move randomly. Any help would be aperciated?

What are you using for power? batteries? wall adaptor?

I am using the battery. it looks just like the pic in the manual under power home position. The servos will move the full range if you move them by hand. But when you use the slider it acts like there is a stop when there is none. Unpowered the arms will move from a hands raised all the way to arms pointing behind him. Powered using the slider his arms only move from arms straight up to almost to his sides like there is a stop there but there is no stop. The software only lets me use 1/2 of his range or motion in the shoulders.

The trim does not do anything at all. I made some adjustments in the trim and nothing happened. But I was told xp sometimes has problems with the software and to try rebooting. so I will try that.

I am useing a laptop, I have all the servos set to ICS. Is there any laptop isues anyone know of and should I have the servos set for ICS or normal?

I didn’t know you could use the charger as a power supply. Is that possible? Or will using the wall charger cause it damage?

I would not use the charger as a power supply. A charger is designed to trickle charge batteries and a wall adaptor uses a built in regulator to provide a steady voltage. If you use a charger as a power source, something might get damaged.

Is the battery fully charged? Sometimes weak batteries can cause jitter and other strange behavior, but from what you are saying sounds like some other problem. Without seeing the behavior first hand, it’s hard to tell if it’s a hardware or software problem.

I would try using the Lynx Term to see if you can get the servo to move to the desired positions and see what happens.

Do you have a link where I can buy a wall power supply?

You will also need this wire harness to be able to plug the adaptor to your SSC-32 or ABB:

Are you sure thats the right one for a KRH-1HV its a 10v robot and the adapter is 6v?

I’m not familiar with that bot. I thought you were using the SSC-32 and or the ABB board.

Ok, I have solved all the problems except why I can only get 1/2 the rotation from the shoulder servos. There must be some software setting or something in the memory of the robot not letting the servo do its full rotation. I cant create my start position until I solve this problem and with no start position I cant run any motions. Anyone have any Idea how to get the software to see that the servo can move farther?

I finally figured out what the problem is. I unplugged the shoulder servos and tried the robot without the shoulder servos and it worked fine. So then I tried it with one shoulder at a time and whenever I hooked up the left shoulder everything went haywire. So I took a closer look at the servo and I could hear something rattling inside it. So I took it apart and there was a raw piece of solder floating around in the servo. So I took it out and all the servos are fine now.
And as for the software issues I tried it on my desktop and everything worked fine. It seems the adapter or something has some issues with Toshiba laptops. So I updated all the usb drivers and reinstalled the software on my laptop. Its still very buggy on my laptop but I am able to run it on my laptop now. So everything is working good now :slight_smile:

Congrats on the problem fix! That’s the best way to trouble shoot by braking things down and doing just as you did.

See, you didn’t need no stinking help. :laughing:
