Hi there, I've just connected a JD robot to my computer and have returned it to all the original setting and calibrations and have found that it still moves in reverse. What I mean by this is that when the robot performs a pre-programmed movement such as the bow, instead of moving it's body forward and it's hands forward the hands and body bend backwards. I've made sure that all of the servos are plugged into the correct ports, in the correct orientation but am still unsure as to what could be the issue. How do I fix this?
If anyone can help that would be greatly appreciated.
Thank you
it’s the robots left and the robots right
so it easily sounds like the wires for left are hooked to the right ones and vice versa on the ezb
swap the left and right servo wires on the ezb.
As for the arms and legs being backward, the servos are either facing the wrong way or the wires are reversed. If something is backward, flipping it around will reverse it. I was part of the ez-robot JD assembly video, did you watch that video when assembling the robot? EZ-Robot has a lot of information on their website. Here's a link to the assembly video: https://www.ez-robot.com/Tutorials/Lesson/61?courseId=1
Thank you.
It sounds like the orientation of the leg servos are backwards. The black screws on the leg servos should be pointing to the middle of the robot, and the wiring order across the bottom of the EZB (when looking at the back of the robot) should be : Left Thigh, Left Knee, Left Ankle, Empty Port, Right Thigh, Right Knee, Right Ankle.
If that doesn't work, try contacting EZ-Robot's tech support team, and they'll be able to walk you through the issue. You may want to send them a picture of the front and back of the robot, while it's in the start-up position. It's possible it's something technical, but 99% of these scenarios are cross wiring. I've done the same thing many many times.
