Leo Rover – small, four-wheeled, open-source robotic platform manufactured and developed in Wrocław, Poland, by Kell ideas sp. z o.o.[1] (Polish equivalent of LLC). The robot entered the market in 2017 (back then under the name Turtle).[2][3]
Design and performance[edit]
Leo Rover is a compact, remotely controlled, four-wheeled rover that is 433 mm long by 447 mm wide by 249 mm in height, and weighs 6.5 kg. Each of the robot’s wheels is powered by an in-hub DC motor with 73.2:1 planetary gearbox and 12 CPR encoder. The wheel tires are made of rubber with foam insert. The robot is equipped with a 5000 mAh Li-ion battery of 11.1 V DC. The rover reaches a maximum linear speed of about 0.4 m/s and an angular speed of up to 60 deg/s. The rover is equipped with a 5 MPx camera with a 170-degree field of view placed at the front of the robot’s body. There are numerous mounting holes on top of the rover to attach additional hardware. The nominal payload capacity is 5kg. The robot has a WiFi 2.4 GHz access point with an external antenna.[4][5]
A significant portion of the robot's structural components are produced through 3D printing. The entire design is watertight at the IP64 level.[3]
Software[edit]
The robot runs in Ubuntu 20.04 with ROS Noetic Ninjammys. Raspberry Pi 4 functions as the rover’s main computer.[5][6]
As for the programming languages used in the Leo Rover robot, the user interface is written in JavaScript along with CSS and HTML. C and C++ languages were used for the rover's firmware. Other components developed by the company that run on a Raspberry Pi are predominantly written in Python. In addition, a large portion of the software used in a Leo Rover is provided by open-source packages available in the ROS ecosystem.[7]
User interface[edit]
The Leo Rover robot has its own, aforementioned UI, which is available as a web page after turning on the robot and connecting to it. Once the interface is launched, the user accesses streaming from the rover’s camera and has the ability to control the robot. Steering can be done on the touchscreen of the user’s mobile device, with the use of a mouse, keyboard, or joystick. At the user’s disposal, there are also the rover’s shutdown and reboot buttons.[8][9]
European Rover Challenge[edit]
In 2020-2022, Leo Rover was the standard robot used in the remote formula of the European Rover Challenge.[10][11]
Name[edit]
The initial iteration of the robot was called Turtle, but in 2019, it was changed due to its similarity to the name of another robot – TurtleBot – which resulted in confusion between the two products among customers. The company changed the name of their robot to Leo Rover – keeping the concept of a „turtle”, the word Leo in the robot’s name refers to the fictional character Leonardo known from the Teenage Mutant Ninja Turtles comic book series.[12][13][14]
Application area[edit]
Leo Rover serves as a development platform for implementing one’s own technological solutions by connecting external electronics, editing the open-source software, or modifying the robot’s design. Although the product is available to both individuals and companies, the majority of the consumers are universities and research facilities that use the robot for their projects and research.[1][3][11][15][16][17][18][19][20][21][22][23]
