Week 9 Motor and Motor controller Purchase

Finally, our budget got approved and we can start buying our parts. We purchased a brushless motor from goldenmotor.com and it will probably take 10 days to come in. The motor is rated 1500W and it way more than enough for our project. We also placed an order on Kelly control for our motor control. The model of the controller is KEB48201X which withstand up to 150A of current. It should be more than enough for our project.

Week 8 general seminar section

Today we had a general seminar section for our Engr195B class. We talked about the second essay that we need for Engr195B and how the analysis helps us to develop a professional career. After the general section, we headed to the workshop and continued to work on the SolidWorks drawing for the electronics. We decided to use pinewood and wood glue to make the box, and it shouldn't be that hard.

Week 7 Solidwork drawing

Since we have decided to make a battery mount on the bogie, I have made a drawing in Solidwork. Here is a snapshot of what I made last week. There is a hole on each layer for cable management. 4 holes for bolting it on to the bogie. The model meets what we need for our control system. I will keep working on it to make a better design.

Week 6 Electronics Compartment

After the meeting today with Solar team, we decided to have a battery on the bogie instead of having cables from the charger controller. We decided to use 12V lead-acid batteries to power our control system. Thus, we need a small box for the Arduino and a battery mount on the bogie. I already have an idea of how is the mount going to look on the bogie. I am going to start some 3D drawings on Solidwork this week and find to best fit for our bogie.

Week 5 Presentation 1

We have presented our idea today. We gave everyone a quick update of our project and a brief idea of what we are going do next. I have included the slides on this blog. Enjoy!

Week 4 First round of Presentation 1

Today is the first round of Presentation 1. We have finished our slide for our presentation but we didn't have a chance to present today. Other teams have shown their progress and plan for this semester. I am excited to see the final product of every team. It will look great after we combine our prototype together and show it during Maker Faire.

Week 3 Preparation for the first presentation

Since next week is our first presentation, we have started the powerpoint slides. We have finalized our bill of materials since we only need to purchase the motor and motor controller. We have included the rapid prototype of our control system in our slide to give the class an idea of how our system works. Here are the schematics of the control unit and motherboard unit.
