Preliminary Design Review!!!

This blog post is a few days later than usual, but that was because we were waiting for the PDR to happen before writing one. We had our Preliminary Design Review on Tuesday, November 27. The presentation went very well. Instead of forcing you to read  over 1000 words to hear what happened, please enjoy the PDR in its entirety by watching the below videos. These videos have also been posted in the media section of this website in case you want to view them at a later time.

Enjoy!

PDR Runthrough Part Deux

One more week until the PDR! We got another chance to present in front of our advisors. Our presentation was better, but the advisors still believed there was room for improvement. A few critiques that they had included not saying acronyms or technical terms without being able to explain them to the audience. The presentation still lacked some rationale for making certain decisions about the project. A good comment was that while we have been living and breathing this project for months, this will be the audience’s first exposure to the project. This really put our presentation into perspective. When we make our final edits we will be taking that into consideration.

 

Short blog post this week as we are all busy working on the presentation. We will keep you posted with how it goes!

PDR Runthrough Part I.

Hello everyone. This week we attempted to run through our PDR presentation for the advisers. While our technical content was very good, the advisors informed us that our presentation was lacking in the design process department. For the next revision we will be including  not only the aspects of the project that we have decided upon, but how we decided that these were the best options. We also had three separate presentations for each team, but for the sake of flow, we will be combining them into one presentation.

Due to our actual PDR being so close to Thanksgiving, the advisers thought it would be a good idea to push the presentation back one week. Instead, our PDR will be on Tuesday, November 27 at 3:00 p.m. Once a room has been booked, we will create a flier and pass the information along.

While the bad news is that we are pushing a deadline to another time, the good news is that we get another attempt to present our PDR to our advisors! Next week we hope to have a more polished version of our presentation. Hopefully, we will be headed on the right track to our PDR.

Countdown to PDR

Hello everyone. We met as a team for the first time in B term on Monday, November 5, 2012. Having not met for quite some time, we dove right into business. Prior to the meeting, the ME team worked on the heat properties and materials of the chassis and housing of  the robot. They also calculated the propulsion and drag of the system using estimates for drag coefficients. They also uploaded a CAD model of the chassis and housing design to the SharePoint. It is lacking components and modules, which will be added at a later time.

The ECE team presented their work on the Abstract Hardware device. The schematic is 90% done and contains block diagrams for all of the systems. They are currently laying out the circuitry for revision 1 of the board. The ECE team also outlined the mandatory sensors and found a battery option and buck converters for the power distribution system.  Finally, they are working on programing the device drivers using the NXP development board.

The CS  team created a dataflow path, which included an itemized list of sensor and control inputs. They outlined that the decision making needs to interpret this data. Also, the CS team proposed a request for comments communication protocol for the SharePoint. They hope this will help sure up communication amongst team members.

Lastly, a the Preliminary Design Review (PDR) was scheduled for two weeks from now! We hope to have prototypes completed at this time to present. Next week we plan to do a run through of the PDR at our General Body Meeting.

Only one meeting into the term and we have hit the ground running. The countdown to the PDR has begun!
