The update from this week is a summary from previous weeks. We are getting to the final step of our prototype. Last week we had a presentation and it went well. This gave us more confidence on our design concept and we will work harder on improving the prototype. An optimal design for the mechanical system has been reviewed by …
Although last week we were able to successfully control the speed of the spooler, problems rose with the different types of plastic being extruded out of the extruder. By running tests at 60 seconds and 120 seconds, we were able to find the rate at which plastic was extruded in grams/seconds. We found out that virgin pellets were extruding at …
This past week, Bon Kim and Damian Torres met up with the 3D printing club to print a prototype of the fins (pictured). However, there were technical difficulties when they tried to print one of their designs, which includes hinges in between part of the fin to make it flexible. I worked on the poster for our presentation at the Winter …
This week we finalized the presentation details for our peer review and started to work on our design poster. In our peer review presentation, we wanted to include our revise budget, the timeline for the quarter, who we selected as our sponsors, potential roadblocks and the progress we have made to manufacture our CAD design. In addition, a draft of …
Week 5 Reflection Since last week, our team has been adjusting the control system on a fly bar helicopter. Adjust the angle based on the transmitter and the data provided by the manual. When the swash plate is at its initial position, the angel of the main rotor is not zero since it needs to provide enough lift to support …
As part of the design for Krobohand, we are using electromyography (EMG) to control the actuation. Through EMG sensors, users will gain greater control of their prosthesis. We originally began working with the Olimex SHIELD-EKG-EMG on an Arduino Uno microcontroller. Using the proprietary software ElectricGuru, we were able to analyze signals from the targeted muscle group through the shield. However, …
This week we received feedback from our peer review. We received 3rd place out of all the senior design projects and we will be presenting on March 17! In preparation for the presentation, we began creating drafts of our poster. We received feedback from Terry and decided we will go through more re-branding. Rather than being called Specialists in Plastic …
We are currently talking to Dolan about the right material and cost for our projects. We expect to get the final parts in next week. For last week, we adjusted some feature that should be in the final device. We adjusted some hole to the right. We increase the diameter of the broken parts. And then we scale it to …
There are still some modifications needed to be made to the rotating mechanism in subsystem 1. Minor adjustment are being to the motor, and star ball. The codes, however was added to our main control system, subsystem 4, and has integrated well. Subsystem 2 has also been integrated with subsystem 1 and 4, the unit is able to dispense both …
For the past week, Alex, Damian, and Timothy have been epoxying the tank. It has taken some time to apply because we have to wait a couple of hours before we reapply to thicken the epoxy layer. Also, I am looking into shirt designs for our team. I have a couple of simple designs, but I hope to finalize it …
