Today I was able to make the belt work so that’s awesome. I still have problems with Articulation 2, the gears of the motors seem to not grab the wall indentations of the 8-shaped piece. Even if I put them at the very top of the shaft of the motors, they just keep skipping the dents and the articulation ends up doing nothing. Since I’m using Thor to complete a Capstone project, I’m gonna set static articulation 2 and work with the rest. Articulation 2 and 3 have taken a lot of time to put together. I strongly recommend you to match the diameter of the shaft of your motors, do not drill the bore of your pulleys… you will lose time and it’s, mechanically speaking, not good. Always use a grinder for your rods. Don’t waste your time using sanding paper. It’s not accurate and most of the time the end result is not proper.
Hi selexin, have you finished assembling the robotic arm? I’m having some mechanical problems with the two motors of articulation 2 (the ones that have helical gears and make contact with the indentations). Let me know if you had any problems with it or which other issues you might be having. My email is carlosnj95@gmail.com and my discord username is Sukistrukis#7685 or sukistrukis.
I would also like to add that our robotic arm was completely printed using resin. We still have problems using articulation 2-3. We found out that the bottom section of this articulation is not aligning properly with the motor gears, so we lifted a bit the gears that go on top of motors of articulation 2 making a better fit with the internal indentations of the 3d printed piece.
I’m just wondering if the use of resin might have been an error as the robotic arm feels heavy. With help (using both my hands to grab art56 and 4) the motors can do the work but as soon as I leave it on its own, the whole ‘head’ falls. I’m 3d printing the head of the robotic arm with PLA to see if that makes a difference.
