After a while, you’ll know which is the correct “upright” starting position.
If it doesn’t work on the first try, repeat the steps above a few times. Your robot should now repeatedly balance in place for 7 seconds, turn right for 7 seconds, and turn left for 7 seconds.įollow these steps if the robot doesn’t balance: Now release the robot and let it balance. Select the program and start it with the center button on the EV3 brick. Do not hold it tightly, but hold it loosely so that it’s just between falling forward and falling backward. Hold the robot upright with its wheels on the ground. If you’ve built Gyro Boy, begin with GyroBoy-Basics. If you’ve built BALANC3R, begin with BALANC3R-Basics. Robotc ev3 download#
You are now ready to download the example program to your robot. Step 4: Running the basic example program This is the part of the program that you can easily customize to create your own program.
The drive control loop controls the speed and steering of the robot as it drives around a room using a simplified move block. You won’t need to change any setting of the blocks in this loop. Robotc ev3 how to#
In turn, it uses this sensor information to calculate how to drive the motors in order to keep the robot up right. It measures and calculates the position and speed of the motors, and it determines the robot’s angular velocity (how fast it’s falling), as well as the robot’s angle relative to the ground.
The balance loop keeps the robot balanced. If you use the NXT HiTechnic Gyro, change the Choose Sensor setting on the Initialize My Block to 1. The example programs come preconfigured with the correct settings for BALANC3R and Gyro Boy if you use the LEGO EV3 Gyro Sensor. For example, the second setting of the first setting specifies the diameter of the robot’s wheels. The configuration blocks let you specify what the robot looks like, so that the robot knows how to balance. The balancing program consists of a balance loop, a drive control loop, and configuration blocks. GyroBoy-AvoidObstacles: Drive around while avoiding obstaclesĮach program consists of two configuration blocks, a balance loop, and a drive control loop, as shown in the figure below. GyroBoy-Basics: Balance in place, turn right, and turn left. BALANC3R-RemoteControl: Control the robot with the infrared remote. BALANC3R-Basics: Balance in place, turn right, and turn left. The project includes four example programs, two for each robot: Launch the EV3 programming software, and open the downloaded project file.īefore you run the programs, let’s briefly examine how they work. Right-click this link, click “Save Link As,” and save the project file to your computer. Installing new Sensor blocks Step 3: Download the balancing robot project If you’re using the LEGO MINDSTORMS EV3 Student Edition, this block is already installed. Robotc ev3 install#
Follow the steps in this article to install the block. If you’re using the LEGO MINDSTORMS EV3 Home Edition Software, you’ll need to install the EV3 Gyro Sensor block before you can program your robot. Step 2: Installing the EV3 Gyro Sensor block 1x LEGO MINDSTORMS EV3 Education Core Set #45544. Click to go to the building instructions. 1x LEGO MINDSTORMS EV3 Home Edition #31313. 
To begin, choose the robot you want to build, and follow the respective step-by-step building instructions. Once your robot is up and running, you’ll be challenged to customize the construction and program to invent your own self-balancing robot. You can build and program BALANC3R (left) or Gyro Boy (right). This tutorial will show you how to build and program a self-balancing LEGO MINDSTORMS EV3 robot that can drive around a room.
