Model: KoalaII
Average Rating: Not Rated

Koala is a mid-size robot designed for real-world applications. Bigger than Khepera, more powerful, and capable of carrying larger accessories, Koala has the functionality necessary for use in practical applications (like sophisticated battery management), rides on 6 wheels for indoor all-terrain operation, and sports stylish bodywork for attractive demonstrations.

In addition to these new features, Koala retains a shape and structure similar to Khepera, such that experiments performed on Khepera can be migrated to the Koala. The BIOS of both robots is compatible, permitting programs written for one robot to be easily adapted and recompiled for the other.

To facilitate programming of the robot, we support several development environments, from standard cross-C developments to more sophisticated tools like LabVIEW® , MATLAB® or SysQuake. Please note however that this software is just a suggestion and not at all needed to use the robot. Any other programming environment capable of communicating over a serial port can also be used. The communication protocol implemented on Koala is described in the user manual.
