Gen 1 proof of concept design prototype – main chassis

The first generation chassis prototype has a 2-halves design due to restrictions in printer capacity.

The Gen 1 prototype chassis deploys a tabular chassis structure, which can be conceptualized as a 3D derivative of a ladder chassis by imagining how the simple, 2D layout of the ladder chassis evolves into a more complex, three-dimensional framework. A ladder chassis itself is 2D, with two parallel longitudinal beams connected by several cross members, which can be relatively weak in torsional rigidity (since it is quite “flat”), which can lead to flexing and instability. A tabular chassis expands it into three dimensions through the vertical plane, creating a grid-like or tubular framework. By distributing the loads across multiple paths and directions, the tabular chassis can achieve a much higher strength-to-weight ratio. HOWEVER, in the case of 3d printing there is a minimum thickness to adhere to just to stay solid structural-wise, and the additional framework components will lead to way more weight.

Overall speaking the chassis structure is over weight due to thickness (for 3d printed structure to be solid there are some minimum thickness we must adhere to).
