Slider Mirror (NASA Lunar Torch)

The main focus is a mirror deployment mechanism, instead of the rover, that is as compact as possible while giving the hinges, springs and motors enough to room to operate.The mirrors create an octagonal reflecting surface. The dimensions of each square are 120cm*120cm the total reflecting surface is 10.08 m^2. The assembly can be packed within 160cm*140cm* 55cm (excluding the rover).the mass is only 119 kg (excluding the mechanical arm)the area of the solar panel comes out to be 1.44 m^2.a mass evaluation sheet from SW is providedMirror Deployment Mechanism:The square mirrors simply slide out on a railing with the use of electric motors (as sliding the mirrors is easier than rotating them about their edges)Once the square mirrors have slid out, the triangular ones unfold using hinges and a torsion spring mechanism. This is demonstrated in one of the picturesThe arm allows for the mirror assembly to rotate around 2 axes.The mass has been calculated taking aluminium as the support material and reflective film coated plastic for the mirrors and can be reduced with composite materials.P.S.As the step file is not showing the proper model (I tried to fix it several times) , SolidWorks files have also been provided for reference.
