In this lesson, we will explain how to connect to your Roli Rover Robot using your PC over a Wi-Fi connection.
*Note: If this is the first time you have used Roli, we recommend calibrating his Lever Servos and Grippers.
What You Will Need
- An assembled and calibrated Roli with charged battery
- A PC with EZ-Builder Installed
Load EZ-Builder and press the OPEN button under the FILE menu.
*Note: Always ensure you have the latest EZ-Builder. When you load EZ-Builder and have a connection to the internet, it will notify you if there is a newer version.
In EZ-Builder, the open file dialog window will display. Press the EXAMPLES button in the top left to open the example robots.
Locate the Roli project and press the OPEN button.
Your Roli project is now loaded.
*Note: If you receive warning messages about missing EZ-Bits or an unfamiliar "Open Assembly Instructions" dialog, then you must not have completed the prerequisites mentioned earlier. Please complete the lessons recommended above in the prerequisites section before continuing.
Turn Roli's power switch to the ON or 1 position. Early Revolution robots have a power switch labelled ON/OFF, while the newer robots are labelled with a 0/1.
*Note: Roli's servos will jolt/twitch when the power is turned on. This is normal behavior as the servos will move when initialized with power.
When the power switch is turned to the ON position, the EZ-B will be flashing Blue. This means it is ready for a Wi-Fi connection. You will be able to see the flashing blue LED through the cover of Roli.
Locate Roli's EZ-B Wi-Fi Access Point in your Wi-Fi Networks List. This is accessed by pressing the Wi-Fi button on your system tray.
Press the CONNECT button and a connection will occur from the PC to the EZ-B v4 in Roli. His servos will instantly initialize into the calibration position.
*Note: It is normal for Roli's servos to make buzzing noises. The EZ-Robot Revolution Servos are Heavy Duty with metal gears, which is how our robots are able to stand, walk and dance. Due to the strength of our servos, they can be a little noisy. It is normal for robots to have noisy joints while holding positions under their own weight, just like in the movies. :)
Advance to the next lesson to learn how to make Roli move and do fun stuff!
