I have constructed my version of jd robot using EzB-v4 ,7.4v Lipo and hi torque 7.4v servos. Works well but the servos are jerky. They work fine individually.
Any ideas? *confused*
Upgrade to ARC Pro
ARC Early Access will give you immediate updates and new features needed to unleash your robot's potential!
What is the MaH rating (and C rating if you have it) for the battery?
The two most common issues with performance are flooding data channel, caused by too many reads on one or more ADC port, or insufficient battery current (although low current usually causes the EZ-B to brown out and disconnect vs jerky servo movement).
You can post your project and we can take a look to see if there are any scripts that look troublesome.
The Lipo is 1300MaH,and 25C rating. Using EZ-B v4.
I have constructed a JD robot using non-EZ servos,which are 7.4v rated.
At the moment legs feet and shoulder servos are connected.when the leg servos operate they are rather jerky when moving.(they move freely and smoothly with no power to them).
It is all connected as in the official JD Robot.
Could it be due to speed of servos and if so how can they be altered.
So the default JD actions are designed around analog servos. To combat Digital servo jerkiness I would recommend changing the Speed, Delay, and Step values for each frame in the "Action" section of the AutoPosition Control.
Start with slowing down the Speed (0 is fastest and 10 is slowest), start with Speed:1, then increase your delay values until your action completes each frame in its entirety and lastly adjust the steps to create the smoothest response you can in relation to the delay value.
