Intel® Joule™ USB-C port is not recognized on Windows 10
Some users have reported that the USB-C port is not recognized on Windows 10 when they were trying to update BIOS. Please check below link that describes the solution that worked out(Thanks for rknlhrqy and VRAORESEARCH).
Can I charge the battery when the battery is connected to Turtlebot3?
Charging and discharging the battery at the same is NOT recommended and this may void the warranty of the product. If Turtlebot3 needs to be turned on while charging/replacing battery, please follow below procedure:
- Connect SMPS 12V 5A to OpenCR
- Disconnect the depleted battery from OpenCR
- Connect the depleted battery to battery charger or replace the depleted battery with a fully charged battery
- Connect the fully charged battery to OpenCR
- Disconnect SMPS 12V 5A from OpenCR
Intel® Joule™ freezes while booting/installation
If BIOS firmware is not properly installed, this might happen. Please burn the BIOS firmware 193 release version again.
- Turn off the Joule.
- Proceed BIOS firmware #193 update using file from the below link. Make sure that you see the message in the red box.
Enable SSH server in Raspberry Pi
First you have to install ssh on [Remote PC] and [Raspberry Pi]
sudo apt-get install ssh
In case of Raspberry Pi (TurtleBot3 Burger and Waffle Pi), since the SSH server of Ubuntu MATE 16.04.x and Raspbian is disabled by default. If you want to enable SSH, please refer to the documents below.
or you can use following commands
sudo service ssh start sudo ufw allow ssh
Before start to connect SSH, you need to check host name. Redbox in below image shows it.
Then, you can use SSH following command in [Remote PC].
Timesync between TurtleBot3 and RemotePC
Note : This solution is subject to connect internet on your Turtlebot and RemotePC under same Network
First, you have to install
[TurtleBot] and [RemotePC]
sudo apt-get install ntpdate
Second, synchronize to NTP server
[TurtleBot] and [RemotePC]
$ sudo ntpdate ntp.ubuntu.com
Turtlebot3 Setup Dynamixels
Download Setup Firmware
As shown in below image, from the example menu, go to turtlebot3 → turtlebot3_setup → turtlebot3_setup_motor, download the firmware to OpenCR board, and proceed with setting process.
After completing the setup, download the proper TurtleBot3 firmware to OpenCR.
Click the Upload button on the Arduino IDE to download and once download is completed, Click the serial monitor icon on the upper right corner of the application as shown in next image.
Connect the Dynamixel to the OpenCR. Note that this firmware only works with one Dynamixel, so you have to connect only one Dynamixel at a time.
Change Dynamixel Setting
When the serial monitor is executed, a menu for the Dynamixel setup is displayed as shown in As shown in below image. TurtleBot3 consists of two Dynamixel actuators on the left and right respectively, so select the Dynamixel based on the assembly position. To set up the left motor, enter
To prevent input mistakes, a confirmation menu is displayed once again. To proceed with the changes, enter ‘Y’.
If you enter
Y, the setup tool starts to search the connected Dynamixel using different baudrates, and ID. If a Dynamixel is found, it will be reset for the TurtleBot3 configuration. When the setup is completed,
OKmessage is printed.
Complete the setup procedure and verify if the change has been properly made. If you select one of the test menu for the motor, the connected Dynamixel with correct configuration will iterate the rotation in the clockwise and counterclockwise. To end the test, press the Enter key again. To test the left Dynamixel, enter
3as shown in below image and enter
4for the right Dynamixel.
