# Excavator

# Introduction

An Excavator is a heavy construction equipment used Primarily for digging, lifting and carrying tasks in various applications. Let’s build an excavator robot using KiMu’s Advanced Automate kit, which utilizes stepper motors to control the excavator arms by a fixed amount of degrees.

# Programming with Automate App

# Configuring the app - Remote controls setup

STEP Buttons are configured as shown in the image below to represent the arrows used in the game. These configurations can be altered by the user according to their needs or requirements.

STEP 7 - Arm 1 Dump
STEP 13 - Arm 1 Revive
STEP 9 - Arm 2 Dump
STEP 15 - Arm 2 Revive
STEP 8 - Forward motion
STEP 14 - Backward motion
STEP 10 - Leftward motion
STEP 12 - Rightward motion

TO "STOP" THE EXCAVATOR CLICK ON ANY BUTTON OTHER THAN THE ABOVE CONFIGURED BUTTONS.

Note: Automate can be controlled using a cable by selecting the cable option instead of Wi-Fi under the remote option.

To upload the program, see How to upload the program to the Control Unit with Automate App?

Excavator is ready to dig after uploading this program.
