Phase I

Sketches of Shapes

Cube

Pros:

Easy; Robust

Cons:

Isn't Outside the Box; Too Easy

Triangular Prism

Pros:

Plenty of surface area for grabbing

Cons:

Half-Movable; Uneven Weight; Disadvantageous Slopes

Hexagonal Prism

Pros:

Universally Grabbable

Cons:

Only can grab from the edges

The plan.

We intend to design a payload of subtle difficulty for our mechanized arm. A spherical payload is the goal. The idea is that by creating a sphere with flat sides, we can create a general and robust mechanism to lift a variety of shapes. It is a technically difficult challenge presented in a simple package. Considerations include the smooth, curved surfaces, and the faces to balance on. Our mechanism will have to act precisely to ensure a smooth motion.

Where are we?

We completed our payload design and displayed it as Figure 1. In Figure 2, its 2D dimensions are displayed as 1.45 in x 1.45 in. Our payload design has a mass of about 11 grams and a volume of about 1.52 cubic inches shown in Figures 4 and 3, respectively.
