Wheel chair of the future

Climbs stairs. Nuff said.
Thrilled to see someone actively working on wheelchairs again. Devices for the differently abled get prototyped and die in labs way to often.
Kudos on sleek design and major functionality. The other stair-climbing wheelchair I've seen requires separate add-on ramp. Hoping final product can intelligently identify which stairs it can/can't climb, if it doesn't already do so.
