== Liberté de mouvement et signaux de contrôle ==
Each of the servos used by the Robot Arm Kit for Romi has a different effective range of motion due to the arm’s geometry. Please note that it is possible to drive the servos in a way that they physically bind the arm and cause them to “fight” each other, which could result in damage to servos or the Robot Arm. Most servos are intended to be used with the 1000 µs to 2000 µs pulse width range commonly used in RC systems; however, many of them can accept a wider range of inputs and will continue responding to them accordingly (moving farther and farther from neutral until they hit their mechanical limits and possibly destroy themselves). The Robot Arm accessory takes advantage of this increased range for the gripper servo. If you followed the assembly instructions correctly, the full range of motion of the gripper servo should correspond to pulse widths from about 500 µs (fully open) to 2400 µs (fully closed). Please note that there could be some unit-to-unit variation in the servos, so if you notice some buzzing when there is no load on the servo, you might try adjusting these values.
