Prototyping Challenge: Day 2

Hello,

Today was day two of our annual prototyping and programming challenge. Once again, we broke up into our 4 prototyping sub-teams and groups of 2-3 programmers.

Sub-team B:

Their main idea and focus is to have a roller mechanism with a forklift and two arms to support the rollers in order to pick up the cones. They determined that using pneumatics would be too complicated to prototype with the time allotted. By the end of the day they figured out that they need to drop the idea of having actuating arms and instead to “use a spring to allow the arms to close in on the cone and release when the rollers are reversed” as per their daily build blog.

Sub-team E:

They are doing a similar idea to team B where they have rollers and a forklift working together. Their main issue has been finding enough jobs to occupy their group. To fix that issue, they divided into two groups- one group finishing the design for the arms and the other beginning to build both arms. They took advantage of their resources by using the laser machine to cut wooden parts. One issue that the team had was the time that it took to design the arms. Their solution is to seek help from student leadership.

Sub-team A:

Small difficulties with the “stick” prototype. The first version of their hook broke due to a misjudged cut. Their new version 2 stick hook is up and running. The conveyor group in Team A has disbanded and are now working on a wrist-like mechanism.

Sub-team R:

They have decided to pursue their arm/claw idea. This is where they have a backstop mechanism and then a “claw” is pivoted and wraps around the cone. They worked on deciding how to mount motors and a ratchet. They also started to work out the poly belt attachment and spacer plates for mounting. Their long term goal is to “have a working prototype and win”. To do so, they want to be able to pick up 5 cones simultaneously with all of them starting sideways.

Programming Challenge:

Some teams were able to get their tele-op programming working today. Others kept working together to keep writing the program and to make fixes.

Programmers work together to make a tele-op and/or autonomous program
