Hi everyone.
Disaster struck my robot lab a few weeks ago. While trying to fine tune my B9's arm elbow motor (because of some control issues leading to jitter and overshoot position) it somehow lost control. I ended up with a runaway condition and it locked the arm fully down against the rail! The result was the elbow motor burning up as I couldn't power it down fast enough. This 10 year old motor is discontinued but thank goodness AM Equipment has come out with a new faster and more powerful version. Best part is that it fits my setup! What a relief! In this video I try to explain that happened ( I still don't really know yet
), show the removal of the old motor and how the new one fits in place. Enjoy!
Hey dave, I still have a good amount of Actobotics U-channel and some other parts I could send you if you need. Hopefully I will have the right ones
@RoboHappy, wow, thanks for the offer. I really appreciate it. Actually I have a ton of stuff myself and dig into it more than I would have thought. I'm glad I stocked up years ago. I can usually rebuild or adapt but it's a pain sometimes. If I come across something critical that I'm in need of I'll reach out to see if you have it. If you do and are willing to part with we can work a deal. Thanks again!
I've finished my B9 arm motor replacement that I showed here a few weeks ago in a "Part 1" Youtube video called "Arm Motor Replacement. Part 1". Things get a little crazy and violent in this Part 2 video when I go to set up this new motor and use the Auto Tune feature on the Dimension Engineering Kangaroo X2 .
Part 1, The last vid, showed the arm taken apart and how the new motor fits in place. This vid shows the motor installed, the arm put together and mounted on the robot. As mentioned above, I also show how I use the Auto Tune feature of the Dimension Engineering Kangaroo X2 to get the motor running smoothly. Things actually get a little scary. LOL. Have fun watching and strap in for a crazy DE Auto Tune ride.
In this final arm motor replacement video I show the end result of my process. After motor installation, adjustments and tuning the motor controller to motor his arm is performing nicely. Here I'll demonstrate how it's working and show some neet animations I've created thanks to what Synthiam's ARC can do! Thanks for watching. Have fun and enjoy!
