  • In this note, user will use package "slam_gmapping"(thanks Adlink for providing) to build map for navigation. Hardware user have to prepare before doing... ROSKY2 Note Navigation2 just can be used on Ubuntu 20.04 A host machine with the operating system is Window 10(above) or Ubuntu.

  • In this example, user can use ROS2 and let ROSKY2 do: find wall automatically with lidar try to near the wall and record odometery at the same time after nearing the wall, ROSKY2 will go along with the wall Hardware you need to prepare before doing... For observing clearly, user need an enclosed space about 180(cm)x180(cm), and the walls should be more higher than lidar on the top of ROSKY2 about 13 cm. And then put ROSKY2 in the enclosed space anywhere you want

  • About author Hello! My name is Wei-Chih also can call me Joe. I am a robotic engineer. Now I promote robotics and AI in educational institutions from primary school to college. There are some tips I usually use below, welcome to visit and hope these can help you to understand how to control the robot. Joe4Learning means "Joe for Learning" in English and "就是要學習" in Mandarin. How to use this book? I list my note and you can find these on the left side, or youc can find the table below.

  • This note will tell you how to setup the Project "ROSKY2" with Jetson nano developer 4G kit. Hardware you need to prepare before writing image To prepare your microSD card, you’ll need a computer with Internet connection and the ability to read and write SD cards, either via a built-in SD card slot or adapter. Notice space of the MicroSD card need bigger than 32 GB. 1. Write Image to the microSD Card 1-1. Install balenaEtcher I suggest using balenaEtcher to write the image with Microsoft windows system. Please visit the official website to download the software: balenaEtcher official website Please click the "Download for Windows(x86|x64)" button to download and then run the file to install. If you can install smoothly then you can see the icon "balenaEtcher" in the desktop.

  • This project is about how to design your own ROS package to have communications with Duckiebot DB21M. You can check this to see the souce code of Duckiwtown. Hardware you need to prepare Please check this to know: Duckiebot DB21M. If you have it, let's go to the next step! 1. Setup operating environment on your host machine. 1-1. Install ROS on host machine

  • Before controling Jetfalcon, you need to setup the operating environment. If you had not done this step, please go to the last step: 0. Jetfalcon and setup environment. Hardware you need to prepare A mobile platform with differential drive configuration. If you don't have and idea, please check more information from Jetfalcon. OK! Let's see how to use teleoperation!

  • Before the navigation, you need to make a map. If you had not done the step, please go to the last unit: 2. Jetfalcon and SLAM. Hardware you need to prepare A mobile platform with differential drive configuration. If you don't have any idea, please check more information from Jetfalcon. Also, recommand using host machine to launch the SLAM. If can, please prepare another host machine with ROS-Melodic. You can check this see how to install ROS on the host machine: ROS Installation.

  • Hello every one! This file will tell you how to install ROS2 on your laptop with virtual machine, so that you can start communicating between the robot and the laptop through ROS2. And I choose Ubuntu 20.04 to run ROS2, because the robots I use usually use Linux system. Hardware before you install ROS2 You need a computer or laptop can connect Internet and I suggest the specifications are more higher than: CPU: Intel(R) Core(Tm) i7-8750H CPU @ 2.20GHz 2.21 GHz GPU: NVIDIA GeForce GTX 1060 with Max-Q Design RAM: 8 GB
