How does the SCEWO wheelchair work?

How, on electric stair climbing wheelchairs like the SCEWO wheelchair, is the power directed from the main wheel to the tracks?

Hi Abel,

Well, the tracks are actually always turning, driven by a chain, but when approaching steps, the wheelchair user presses a button to lower the tracked wheels, which then take over until up or down the steps.
