ROSbot is an autonomous robot platform based on Husarion CORE2-ROS robot controller. It integrates:
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.
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.

ROSbot is supplied from an internal, rechargeable Li-Ion battery pack (3x protected 18650 cells). ROSbot shall be charged using a dedicated Li-Ion or Li-Poly charger with 4-pin JST XH connector. 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 overdischarge protection. If the voltage is too low please charge batteries as soon as possible.
If you are going to use ROSbot stationary for a long time, please leave the charger connected all the time. It will increase the batteries lifetime. In case you need to replace batteries, use only 18650 Li-Ion batteries, with the capacity in a range of 1800...3500mAh and with a protection circuit! Using unprotected batteries may result in serious injuries or fire.
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.
