Bras Robotique Arduino Braccio

The Braccio arm went together very cleanly and fast with no surprises. I has afraid that its size would make it unstable but it is very solid and stable. The coding provided made getting the arm to things very easy and fast with limited lines of code, a bonus. It is also very accurate for its size, in one routine it returned the ball to the exact location every time +-2mm. Thanks

Le bras de Braccio est allé très rapidement et proprement sans surprises. Je crains que sa taille ne le rende instable, mais il est très solide et stable. Le codage fourni rendait le passage au bras très facile et rapide avec des lignes de code limitées, un bonus. Il est également très précis pour sa taille. En une routine, il a renvoyé la balle à l'emplacement exact à chaque fois + -2mm. Merci

The robot arm has excellent build quality. The size is also quite big, which is great.

Le bras du robot a une excellente qualité de construction. La taille est également assez grande, ce qui est génial.

I was concerned with jitteryness and ease of use and strength. But I was impressed at the cost/quality ratio. It's a solid little arm that has the libraries built in and works great. The only things I dislike are: 1) If you feed the script anything other than a perfect value in the Bracio's range... (lets say you fed it a negative angle or "140a" instead of "140") Then the arm "dances" and will bump itself into things and wreak havoc on your work area or those poor servos. 2) Calibration is an entirely manual process. I couldn't figure out how to open the library to "calibrate" the arm by moving the range from "0 - 180" to "-5 to 175" for example. The only recourse seemed to be to limit your motion from 0-175 and lose 5 degrees. (or try your hand and manually straightening the arm out which is a pain). Still even with these quirks, the arm is a 5/5 given how little effort it takes to get up and going.
