VGK-Go! for medium- and long stump


The VGK-Go! is a Fluidic Processor Knee (FPK), and the original design in the VGK range.

It is a default stance knee with stumble recovery, which gives you a high level of safety. By continuously monitoring the motion of the knee, the VGK-Go! can detect a stumble and immediately provide high bending resistance to allow you to regain balance.

The VGK-Go! adapts well to different situations. Its sophisticated control system works in real-time, so that you can walk well at different speeds, navigate uneven terrain and perform leg-over-leg stair descent. The VGK-Go! senses these changes in walking patterns and adapts within a single step. It does so without batteries and therefore without the need for charging.

With its high level of safety and adaptable behaviour, the VGK-Go! is perfect for daily life. And without the need for charging, the VGK-Go! is perfect for adventure.
