ich stell die ursprüngliche frage mal anders herum:

mit diesem sketch:
Code:
/* meArm_Adafruit IK test - York Hackspace May 2014
 * Test applying Nick Moriarty's Inverse Kinematics solver
 * to Phenoptix' meArm robot arm, to walk a specified path.
 *
 * Pins:
 * Arduino    PWMServo
 *    GND         GND
 *     5V    VCC & V+
 *     A4         SDA
 *     A5         SCL
 * 
 * The Servos attach to the first block of four servo connections on
 * the Adafruit board, brown wire at the bottom, yellow wire at the top.
 * Adafruit    Servo
 *       0      Base
 *       1  Shoulder (right)
 *       2     Elbow (left)
 *       3   Gripper
 *
 * You can attach to a different block of four by changing the 'begin' call
 * to specify a block 0-3, e.g. to use the second block call arm.begin(1);
 * - to mirror movements to all 4 blocks, call arm.begin(-1);

}
werden diese bewegungen erzeugt:

was haltet ihr davon, ist es für den aufbau ok und sollte ich meine erwartungen runterschrauben?
