5. Setup
5.1 Initial Charging
Before first use, fully charge your Thymio II robot. Connect the provided USB cable to the robot's USB port and the other end to a computer or a USB wall adapter. The robot's LEDs will indicate charging status (refer to the Quick Start Guide for specific LED patterns).
5.2 Software Installation (Optional)
To unlock the full programming capabilities of Thymio II, you will need to install the Aseba software suite on your computer. This software allows you to program the robot using visual programming languages (like VPL) or text-based coding. Visit the official Thymio website (usually mentioned in the Quick Start Guide) for download links and installation instructions.
6. Operating Instructions
6.1 Basic Operation
The Thymio II has pre-programmed behaviors that can be activated by pressing buttons on its top surface. These behaviors include exploring, following lines, reacting to obstacles, and more. Consult the Quick Start Guide for a detailed explanation of each pre-programmed mode.
6.2 Programming the Robot
Using the Aseba software, you can create custom programs for your Thymio II. This involves dragging and dropping visual blocks or writing code to define how the robot reacts to its environment using its sensors and controls its actuators. Tutorials and examples are available on the official Thymio website to help you get started.
6.3 Using the Drawing Function
To use the drawing feature, insert a standard pencil into the designated slot on the robot. You can then program the robot to move in specific patterns, drawing on a surface. Ensure the pencil is securely held and the surface is suitable for drawing.
