Phase (2)

Conceptual Designs....

picking up where we left at the end of phase (1), we started sketching our own designs. some where some how illogical and got rejected on the spot. others however were seriously taken into consideration; those were the one we picked up for the next level where we implemented 3Ds conceptual designs of them on Autodesk inventor

The first design was a gear-gear mechanism

main reason why we thought of something else was because of the gear backlashes which will lead to inaccuracy in the angles.

Second one was a gear-belt mechanism

we were trying to avoid the backlashes by using a toothed belt instead

third one was a belt-belt mechanism

it was less complicated and no gears used, but I don't' have an available pic for that one though

fourth one was a lame trial for something different

it was when we decided that these mechanisms were still too complicated, so we shifted our thinking completely and decided to make a swinging mechanism. we were already trying to avoid this cause we will then have to calibrate the angles and we didn't wanna do that :D , still trying to simplify the programming phase. yet, we gave it a shot.

fifth one was the swinging mechanism

in that one we enhanced the mechanism before it, more logical dimensions also :)

Sixth one

that was our final design that we actually implemented.... it was redesigned several times in the actual implementing but I will be posting it's picture and some details on the next post isA
