Humanoid robot A1: robotic arm position repeatability test

Here I let the arm of my A1 humanoid robot repeatly draw two little figures. The congruency of the figures gives an idea of the precision of the arm's position control. Under the specific conditions of this test the repeatability was roughly +/- 1 mm. If this precision applies for the entire range of oparation of the robot remains to be shown, since only two "points" were tested here.
