R2 Aluminium feet drive frames

i made some new designs on the feet drives and let them got lasercut from my buddy at the metalshop:

here are some pics from the work and the assembly of the drive parts like wheel, belt and motor unit:

the lengthened tubes and threaded rods:

during assembly:

the mounted tubes and threads:

the shortened end (not the final look):

some minor errors in construction lead to a redesign of the frame construction...

length and width aren´t what i wanted to have them...i need to have them more compact...

so another ride to my buddy at the metalshop for a new construction is necessary...
