original claw

The claw was a last minute design created in response to the change to a slide. The claw compresses to grab the cone and uses a four bar design. This design was inspired  by a public design found on Onshape and modified to fit our needs.

MODIFIED CLAW

The design was modified for the second qualifier. The grip part was redesigned to fit the cone better. The base was modified to allow for an upright servo and for more stability. The grips were modified to include a connection to keep them in place and in line with each other. The servo is now mounted to the gears themselves and the design uses bezier curves for a smooth look. The design was also broken down into multiple parts and there were given identify numbers. This was the first time we printed using supports. The support hole on the base was centered to allow for more support and extra holes added more places for attachments.

Beacon
​

The beacon design was based off of the teapot statue in old Salem that marks the beginning of the historic area. The original design was one large teapot, however it was changed when it became clear it would not work with the intake design. ​

Chassis 

​Code Sisters uses a standard strafer chassis with few design modifications

ARm

The original design of the robot featured an arm. The arm used timing belts and tetrix channels. The arm was first designed via simple drawing and expanded on from there.

issues

There were many issues throughout the process. Instead of giving up, we work through them and persevere!

1. The 3D printer printed at 1/3 the size, this meant that we were unable to use 3D models of servos and real parts to guide the CAD. To fix this problem we used a lot of calculations to find the right size and dimensions. In the worse case scenario, we were able to solder the holes into the correct place.
2. The 3D printer broke! But we found ways to make the design work in other ways.
   
3. Designs fell through. ​We learned valuable lessons and kept moving forward.
