ROSbot is an autonomous robot platform based on Husarion CORE2-ROS robot controller available in two version: 2.0 and 2.0 PRO.
ROSbot is an affordable robot platform for rapid development of autonomous robots. It can be a base for custom service robots, inspection robots and robots working in swarms. Both version integrates:

You can use your ROSbot offline however we recommend connecting to Husarion Cloud as it gives you access to a lot of additional functionalities like remote management and firmware updates.
If you do not own ROSbot yet, you can purchase it here.
You can also test the performance of ROSbot using our simulation model in Gazebo environment. It is available here, at our GitHub page.
You can find free ROS tutorials dedicated for ROSbot under this link. They will guide you through different aspects of programming autonomous vehicles in ROS

ROSbot is powered from an internal, rechargeable Li-Ion battery pack that contains 3 Li-Ion cells, connected in series. This type of connection is called “3S”. The schematic below explains how the cells are wired together and with the charging connector (on ROSbot side).
The BAT+ and BAT- are the power connections and the “bal Bxx” wires are used to monitor the voltage on each cell. It is strongly recommended to keep equal voltages on each cell during the charging process. The charger included with ROSbot can charge batteries in the described way and, thanks to that, the long life of the battery set is possible.
The nominal voltage of each cell is 3.7V but the useful range is 3.2V to 4.2V.
Important - discharge indicator If only the right firmware is preloaded to the internal controller (CORE2), the LED1 is programmed to indicate the power status:
Please make sure that the user firmware always contains the function that monitors the supply voltage level. Deep discharging of batteries may decrease their lifecycle. Discharging to the voltage lower than 3.0V/cell can also trigger the over discharge protection. If the voltage is too low, turn ROSbot off and charge batteries as soon as possible.
The ROSbot kit contains the Redox Beta charger. It is an universal charger, suitable for charging NiCd, NiMH, Li-Po, Li-Fe, Li-Ion and Pb (AGM, VRLA) batteries. ROSbot shall be charged using an included charger and cable.
Charger kit includes:
Quick charging guide:
If you need more information about charging, please read the Charging manual for ROSbot in PDF format.
Software for ROSbot can be divided into 2 parts:
OS based on Ubuntu 16.04, which runs on the SBC (ASUS Tinker Board) and contains all components needed to start working with ROS immediately. The microSD card with OS is included with each ROSbot. The OS has been modified to make the file system insensitive to sudden power cuts.
In some cases you will need to flash the OS image to the microSD card once again:
ROS (Robot Operating System) provides libraries and tools to help software developers create robot applications. It provides hardware abstraction, device drivers, libraries, visualizers, message-passing, package management, and more. It's very powerful and functional tool dedicated to design robots. We created the set of ROS tutorials dedicated for this platform to make it easier to familiarize yourself with these frameworks.
By default ROSbot supports WiFi in 2.4GHz band, this is sufficent for most cases. If you encounter problems with data transfers e.g. due to processing large amounts of data or noise from other networks you can try to use connection in 5GHz band.
To do this, you will need a USB 5GHz WiFi card (any device based on rtl8812au should be fine, tested models are TP-Link Archer T4U and D-Link DWA-172)
If you have recent image version you can skip update and kernel instal, otherwise do:
sudo apt-get update
This will update packages list.
sudo apt-get install tinkerboard-kernel
This will install the newest available kernel version, that supports 5GHz WiFi.
Load kernel module:
ifconfig to list network interfaces.
You should see now new interface named
Now, You can list all available newtworks:
sudo iwlist wlan1 scanning | grep ESSID
You can connect to your WiFi with:
nmcli d wifi connect <ESSID> password <pass> iface wlan1
Remember to replace
pass with name and passowrd of chosen network.
ROSbot will try to connect to this network each time it boots.
