HI, I have a couple of questions about the project. 1) I want to make robotic arm based on your project but larger and with greater payload. But it probable require to set new Denavit-Hartenberg parameters. Is there any easy way to determine them? 2) Why did you install the encoders on the motor shafts, and not on the joints of the arm itself? Isn’t it better for determining the real coordinates of the arm? Does the program allow installing encoders on the joints? Great thanks for this project, it's just unbelievable!
The software allows you to put in your own custom denavit hartenberg parameters. you could put the encoders on the actual joints if you wanted to but mechanically that was a little bit difficult for me as I would have had to redesign some of the components to have through shafts whereas putting encoders on the motors made a fairly streamlined change.
I have been following your robot arm project for a couple years. this is the year I start building my own Scara robot on a track! Can't wait. Thanks for all your effort and open source software!
Hi chris this video is amazing you have gone to a lot of trouble I’m planning to watch every one of your videos. The challenge with any robot is the software code and you have even covered that. If I lived in the US I would come over and buy you a coffee. I see the payload is up to 2 kilos I wonder if you maybe interested in a 10 kilogram payload
Hi, this looks so great. I also planning to create an arm robot. I'm just wondering whether to use can bus for controlling every axis or not. Is it good idea to use can bus to control every axis? I hope you can help me to choose the best option Thank you so much
You can jog each joint individually but when you execute a move command it will command all motors to move together to whatever position you have asked
@@anninrobotics Can you tell me where the IK Calculation is done at github cause i really struggle to understand it. Or can you recommend me a tutorial of the IK Calculation with DH?
Hello Chris, can you give me information about the CUI encoders, in Argentina I can't find it, can I replace it with another? or else pass me the data sheet of the one you used. thank you very much I send you a big hug
heres on online vendor with info www.digikey.com/en/products/detail/cui-devices/AMT102-V/827015 The latest AR4 motors from stepperonline have the encoders attached.
I'm working on some software updates to make the robot compatible with RoboDK which should be out soon, currently the software doesn't have any simulation capability.
for some reason, i get a permissions error on using my USB port - i just get an error saying access is denied and the program freezes after i "set com" - any ideas?
