Introduction

The robot can run a program in two different modes:

  1. Live mode: In the Live mode, the robot is connected (physically or wirelessly) to a computer while it executes the program. You can change the program and rerun it, and the robot will run the new program. The robot will also send data back to the computer. In particular, this mode allows you to see the sensor values in the panda window in the makeblock program.
  2. Upload mode: In the Upload mode, the program is compiled and uploaded to the robot using a USB cable (or wirelessly). The robot will run the loaded program as soon as it is switched on. The robot can operate without being connected to a computer. If you want to change the program, you need to upload a new version. More information about the Upload mode and how to use it using a USB cable is provided below (USB connection modes ).

We typically use the Live mode in our lesson plans (except for the Color Vision Lesson plan). However, the Live mode no longer works if someone uploads a program to the robot. To reenable the Live mode, you need to reset the robot. The steps for doing this are given below.

<aside> 💡 If you have just started working with the robot or the robot has not been used in Upload mode, you do not have to follow these instructions. However, it is convenient to understand these two modes of operation as we will be using the Upload mode in the Color Vision Lesson Plan, after which you might wish to reenable the Live mode.
