We have a L6 arm that we are programming through Rios. We had to mogify the grippers to mahe them bigger. When we control the arm manually it works fine but when we build a program and hit play it work sometimes and then other times it doesn’t. When it doesn’t work it dies at the end of the routine and goes limp. Any ideas?
I’m trying to pick an aluminum can. Is this too heavy? I wouldn’t think it would be if I can pick it up manually. Can I increase the torque? I’m about to go crazy with this thing!!
Try powering the VL with a 9vdc battery and removing the VS1 = VL jumper on the SSC-32. This will eliminate the chance that the servo controller is resetting due to the servos drawing too much current.
I do not have the luxury of seeing the gripper modification. If it’s made with cold rolled steel it could be that the gripper mod is causing the problem. An empty soda can should be a breeze to pick up.
If it’s not the VL/VS problem it could be the timeouts section of RIOS that needs to be adjusted. Make sure you are using the latest version and read the help file to see how timeouts effect the serial communications reliability.
We are also using the Bot Board and 6 volt .5 amp hr battery to run both servo cotroller and micro controller. We have a power supply here in our lab so is it ok if I use it to supply 9 volts and current limit to 3 amps? The power supply that you guys shipped us is 6v 2amps.
Is there any way we can modify our grippers so that they are wider? I saw where you told somebody in another thread how to do but I don’t know if they are using the same are.
glad it helped. Now you still need a better power supply to get the most power from your arm. Just because it’s not resetting the SSC-32 anymore doesn’t mean there isn’t still a problem with the servo power supply. As for the gripper modification. Not sure what to say. You will need to, you know… modify it. I have received the parts to modify the Little Grip and it seams to work. I will post images when I can. Good luck with it!
