Quick Guide on Ezblock

There are 2 parts here:

• Before Assembling PiCrawler allows you to keep all the servos at 0 degrees to complete a proper and safe assembly (otherwise you will probably damage the servos).

• Before Programming With Ezblock will guide you to download Ezblock Studio to play with PiCrawler.

Before Assembling PiCrawler

Before assembling the PiCrawler, follow the instructions on how to install the Ezblock OS on an Micro SD card here: Download and Install Ezblock OS.

After burning the Ezblock system on the SD-card, the P11 port on the Robot HAT is set to calibrate the servo angle to a 0° angle. To make sure the servo has been correctly set to 0°, first gently insert a rocker arm in the servo shaft, then slightly rotate the rocker arm to a different angle.

Next, insert the servo cable into the P11 port as shown below:

Turn on the Power Switch to the Robot HAT, and the servo arm should return to the 0° position. If the servo arm does not return to 0°, press the RST button to restart the Robot HAT.

Note

Before attaching each servo, plug the servo cable into P11 and turn the power on to set the servo to 0°.

This function will become invalid after writing any programs to the Micro SD card.

Before Programming With Ezblock

First download Ezblock Studio 2, and then manually upgrade to Ezblock Studio 3 to begin programming.

For a detailed installation tutorial, please refer to: Install Ezblock Studio.

Note

After you connect the PiCrawler, there will be a calibration step. This is because of possible deviations in the installation process or limitations of the servos themselves, making some servo angles slightly tilted, so you can calibrate them in this step.

But if you think the assembly is perfect and no calibration is needed, you can also skip this step.
