) as I bring my foot ( well not my foot but you know what I mean)forward it swings thru untill it stops and then locks ....even if the knee is not fully straight ,so it doesnt bend again and throw me on my face, at this point if I realise its not straight I can continue to fully straight . Cunning thing looks for rythym and if it detects anything abnormal ( like if I trip or miss-time a step ) it locks . Ramps are going to be interesting , once I take a few steps it recognises the situation and alters lock points ( there are sensors in the foot bit ....which is waterproof ) . This is going to be a hoot when I get a bit pissed
