# Team P

## Introduction

In designing this Robot Arm, we first began working individually. We then tested our individual designs to determine who had the best design. After finding the robot arm with the best score, we began modifying that design to increase the score as the Pα and the PΩ groups. Pα and PΩ then combined as Team P. As Team P we looked at the two designs we had and combined features from both to create our final design.

## Team Pα Best

After comparing Pα designs, we determined that the design below was the one with the best score.

Team Pα Best

Score = Volume x Maximum Deflection

```     = 0.88 in^3 x 0.228 mm
= 0.20 mm-in^3
```

## Team PΩ Best

After comparing PΩ designs, we determined that the design below was the one with the best score.

Score = Volume x Maximum Deflection

```     = 0.77 in^3 x 0.275 mm
= 0.21 mm-in^3
```

Chamfered Pα Design

After combining Team Pα and Team PΩ we determined that Pα had the lower score. However, we thought that PΩ's idea of chamfering the cuts would reduce our mass while only minimally raising our deflection thus lowering our overall score. After testing this design we received a score of 0.21 mm-in^3 and saw that the lowest score remained Pα's design.

## Team P Best: Overall Best

Continual testing of various designs led to using smaller cut-outs to decrease mass. Ultimately. a honeycomb structure, with a solid portion along a diagonal (to counter the bending at the notch), gave the lowest score.
