Wood takes significantly less time to CNC and is a lot cheaper, so using it for prototyping maximized efficiency for our team. We extended the first axle 1.5 inches in a straight line coming off of our current geometry. Once we began testing, we noticed that although our problems were solved, some new ones arose. For example, now that there was a bigger gap, a ball could fit in between the two axles and get jammed, In order to prevent this, we designed a notch that stems off in between the two axles that we will attach a Lexan strip to. The Lexan will stop the balls from popping up and keep them in line with their planned trajectory. We also noticed that because the intake blades are technically longer, we are again outside of frame perimeter. After some brainstorming, we decided to keep all of our mounting locations and the original piston, and just change the length of the clevis to simulate a longer stroke length. This meant we had to design our own clevis. We decided to make it out of scrap pieces of axles from previous years. We cut them to the right length, and then tapped them farther than we needed to give us room to adjust our stroke length. </ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;"></ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">== Iteration four of intake ==</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">We took the the CNC machine once again to CNC new side blades. We added all of the updates changes and then implemented them on our robot. Finally, we tested it for two days, running normal drive practice and letting programmers mess around with it. After we were confident that we solved all of our problems, we CNCed the final plates out of Lexan. The only difference with the final version (iteration five) is that it has rivet holes for the belt guards and to rivet the sides together. The final blades came out great, and our hard work finally paid off!</ins></div></td></tr> </table>

In order to solve this, we discovered that we had to move the first axle forward, so it grabbed around the ball. We tested this by clamping small metal bars with bearing holes to the edge of the intake and running the axle with a drill through it. Once we had it so that it worked 30 times, we took measurements of the axle placement and redesigned it. </ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div> </div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">== Iteration three of Intake ==</ins></div></td></tr> </table>

Because these slots were hand made, they were consistent on each side which caused them to be uneven. 2) Additionally, the stroke of the piston was interfering with the spacers. Although this wasn't the end of the world, eventually it could lead to our strokes bending, which would not be good.</ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;"></ins></div></td></tr> <tr><td colspan="2" class="diff-side-deleted"></td><td class="diff-marker" data-marker="+"></td><td style="color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #a3d3ff; vertical-align: top; white-space: pre-wrap;"><div><ins style="font-weight: bold; text-decoration: none;">After Rally, are biggest concern became our interference with our hangar mechanism. Although our pistons are out of hangar space, we forgot to account for the pneumatic wiring in this said space. So even though our cylinders don't interfere with hangar, our wires interfere with their pistons. Since our pistons are easier to adjust than theirs, we agreed to move our pistons.</ins></div></td></tr> </table>

You know what that means? We have to finish this robot VERY soon so that we can give it to the programmers!! Today, we noticed that our intake wasn't level because the storage axle was not parallel to the ground. We had to shift one side of the storage down, but luckily we had prepared for this with our design and made each axle able to independently and efficiently shift downwards. We also riveted a thin piece of Lexan around the belts to protect the cargo when it passes through. We also replaced all of our 5mm belts with 9mm belts so that we have more control and rigidity over the axles. Intake is now officially done and ready for rally!</ins></div></td></tr> </table>
