Robotic Arm for Arduino Coding Programming 6DOF xArm 1S STEM Educational Building Robot Arm Kits, 6 AXIS Full Metal Robotic Arm Wireless Handle/PC/App/Mouse Control Learning Robot

super

Jag använde min sommarsemester till denna robot, köpte arduino + sensorer enligt "UNO secondary development kit", och fick då lärda mig programmera. Imponerad av kvaliteten och hur skoj det var.

very bad, the look is great, but not working as expected. You cannot use the PC controller while the adapter is plugged, HOW COME? I returned it

Après avoir passé ma commande sur Amazon, le xArm 6 DOF est arrivé très rapidement en moins de 72 h. Emballage robuste et soigné livré par transporteur. Le montage est très facile et l'aspect final très joli. Pour ce qui est du paramétrage, de la prise en main et du fonctionnement, j'ai été agréablement surpris par le soft qui est très facile d'utilisation que se soit via le PC, souris, smartphone ou encore manette de jeu. Je n'ai aucun regret pour cette achat, chère soit ... mais très intéressant avec d'énormes possibilités d'utilisations. Si vous aimez ce genre de kit à monter, alors n'hésitez surtout pas. Un grand merci à LEWANSOUL pour le xArm 6 DOF qui est impressionnant en fonctionnement.

This was my first experience with a robotic device. I wanted to see how versatile this product could perform. I first used the PC software that was downloaded from Lewansoul, which allowed me to "program" each of the servo's positions and action time. They call this "action groups". You can move the arm to a specific position either manually or using their software, and have it read the angle which puts a value of each of the 6 servo positions as an entry into a table. The table then is used like a program, starting from the first row downward executing each action with a specific time you set. It actually works quite well, and is somewhat precise in positioning the arm repeated times. Each servo has a precision of 0.24 degrees. If you do the geometry calculation, the variance at the full arm's length (approx 14") comes out about 0.058" or about 147 microns. For individual joints, at a distance of 1", results in an accuracy of 0.004" (or 10 microns). With this type of precision, you can do some fun experiments. I had it pick up a washer and had it drop it on a bolt. I could not take a nut and put it on a bolt, though I could have it thread the nut if it was on the bolt. I also had it "mix" a drink by picking up various plastic cups and pouring them into a glass, then shake the glass. I next hooked it up to a Arduino board and wanted to use the arm's controller for secondary programming. After some initial communications issues, which were fixed by Lewansoul providing the correct library for the Arduino sketch program, I was able to have it do some maneuvers and call stored action groups that were downloaded to the controller board from the PC software. As this is a new product for Lewansoul, I found it missing some documentation on the assembly instructions and certain feature operations, and after contacting their support, provided me with what I needed to know. It took me about 4 hours to build the X-arm. Much of the time was sorting out the numerous screws and while they have an excellent animated video showing how to construct the arm, I found myself trying to figure out what metric screw size was what in the kit. They should have a picture of each screw size, so you can match it up to the size you use for the assembly. The component list was incomplete, and it took a while to figure out where everything belongs. Aside from that, the assembly went quite well. In the video's, you'll see I put some soft putty on the edge of the grabber, so it does not slip out of the grasp. Also, if the servo tightens too much with bare metal, for some reason the servo does not want to release the grip. I have to ask Lewansoul about this behavior. I will be doing more "experiments" with the Arduino board, to give the X-arm more intelligent tasks. I will report back in the future with what I was able to accomplish.
