Koala is a mid-size robot designed for real-world application research. 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 Koala. The BIOS of both robots is compatible, permitting programs written for one robot to be easily adaptted and recompiled for the other.
- Compact size
- High precision construction
- Open modular design
- High on-board computational power
- Upward compatible with Khepera software
- Developed to perform experiments in closer to real world environment
- Unique differential drive mechanism to allow zero radius turning
- Accepts most Khepera options
