Hello, I need assistance in understanding why my robot is controlling itself. It is supposed to be controlled from a laptop keyboard and it works fine at times but at VERY IMPORTANT times it starts to go crazy like its spazzing. I was testing my teams robot in the operating room at our local hospital to see if it would work with the robotic microsurgery equipment but it kept going crazy! We are trying to use the arm to help with the irrigation that goes on during surgery. Attached below is a video of the situation but the arm gets worse at times. I figured out that one of the arms joints is most likely the cause but it would be helpful to here other peoples opinions to help solve this problem. Please respond asap, it would be much appreciated!
There is a tutorial on EZ-B diagnostics under the support page.
Similar can happen if the software is attempting to move a servo to a position and the supply is not man enough, or if the servos draw too much current for the EZ-B (the limit is 5A total on the EZ-B regulator). Check the maximum current draw all servos may have if they all try moving at the same time, if it's over 5A you will need to provide an external VCC to the servos.
this is my favourite
especially when the load is over a few amps a quick glance at meter will tell if you have a voltage drop
My robot did that with low voltage.
I purchased a rechargable battery pack from Radio Shack.
Bravia,
That looks great.
Do you have a link for that?
Thank You
