Humanoid Shoulder Calibration
If your Humanoid's arms are significantly twisted from straight up and down, while the robot is in it's Calibration Position, the servos may need to be physically calibrated. This process should only need to be done once per servo.
This process is easy and should only take a few minutes. It will require a screw driver to remove the EZ-Clip to realign it at 90 degrees.
What You Will Need
Insert the EZ-B v4 into the robot body
Turn the power switch to the ON or 1 position. Early EZ-Robots have a power switch labelled ON/OFF, while the newer robots are labelled with a 0/1.
When the power switch is turned to the ON position, the EZ-B will be flashing Blue. This means it is ready for a Wi-Fi connection.
Locate the EZ-B Wi-Fi Access Point in your Wi-Fi Networks List. This is accessed by pressing the Wi-Fi button on your system tray.
Open your web browser and type 192.168.1.1 into the top bar. Press the Diagnostic button from the left side menu.
The Diagnostic page will now be displayed. Press the button labelled "All Ports Servos 90 Degrees". This will set all 24 of the digital ports on the EZ-B v4 to 90 degrees. Any servos that are connected to any digital port will now move to what it has been calibrated as 90 degrees. In the next steps, you will see how to calibrate the servo to be aligned at 90 degrees. You will repeat the next steps one at a time per servo.
Connect both servo wires to any of the EZ-B v4 digital ports. The servos will now move to what they believe 90 degrees is.
Once the shoulder servos are connected to the EZ-B v4, they will move to what they think is 90 degrees. Consult the image above to see what 90 degrees should look like. The shoulder brackets should open from the top and parallel with the edge of the body.
After viewing the shoulder bracket alignment in the previous step, the servo may need calibrating. If the servo needs calibrating, use a Phillips screw driver to remove the screw that holds the brackets onto the servo gear.
Now that the screw is removed, you can separate the bracket from the servo by pulling outward.
*Note: Do not disconnect the servo from the EZ-B v4 until instructed to do so.
Reinsert the bracket onto the servo gear. Notice the orientation of the bracket and that it is parallel with the edge of the body.
Insert the screw back into the servo gear which holds the bracket and tighten it snug. Do not overly tighten, you do not want the screw to dig into the plastic. The strength of the lever from slipping is dependent on the teeth of the gears and not the tightness of the screw.
You may now perform the same procedure on the other bracket of the Humanoid Body. The humanoid body has two brackets, left and right. Repeat this procedure to the bracket on the other side. Once you have completed calibrating both brackets, you may remove the servo wires from the EZ-B.
