The omnidirectional MPO-700 is the ideal base for high-end service robots. Its four

Omni Drive Modules

able it to move extremely smoothly into any direction. This robot is even capable of rotating freely while driving to its
destination. The Omni Drive Modules of the MPO-700 feature important benefits compared to other omnidirectional
drive kinematics, like for example the MPO-500’s Mecanum wheels.

• Fully omnidirectional manoeuvrability

• Very steady movements

• High stability and payload

• Compact, easily integrated drive units

This makes the MPO-700 a premium alternative for applications that require omnidirectional movements without the
limitations of traditional kinematics.
