Anyone else thinking of Dextre as a "he" rather than an "it". It was mentioned in the conference, and i have to agree. With its almost human like appearance i do think of it as almost human <div class="Discussion_UserSignature"> </div>

Apart from maniacal laughter scenarios, I do tend to think of it as a "he".&nbsp; It's kind of an eerie device, really. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

<p>If mr. Dextre is he, when the CSA will build ms. Dextress to avoid him being lonely? </p><p>Sorry guys, but I couldn't help myself and I had to post this stupid offtopic "joke" kind of. </p> <div class="Discussion_UserSignature"> </div>

Hey, I'd be cool with seeing a Mrs Dextre up there.&nbsp; ;-)&nbsp; Robotics are cool, and robotics in space have that extra tinge of nerdy goodness. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>
