english: So I'm an academic at MIT, and I'm a mechanical engineer, so I can do things like look at the type of terrain you want to travel on, and figure out how much resistance it should impose, look at the parts we have available and mix and match them to figure out what sort of gear trains we can use, and then look at the power and force you can get out of your upper body to analyze how fast you should be able to go in this chair as you put your arms up and down the levers.
non_english: Ja sam akademik na MIT univerzitetu i inženjer mašinstva, tako da mogu da radim stvari poput sagledavanja terena na kom želite da putujete i otkrijem koliko će vam pružiti otpora. Mogu da izmešam delove koje imamo i otkrijem kakve zupčanike možemo koristiti i onda uzmem u obzir snagu i silu koju možete izvući iz gornjeg dela tela i analiziram koliko brzo biste mogli ići u ovim kolicima dok pomerate ruke gore i dole niz poluge.
