Our immediate priorities include preparing the exhibit materials and refining the presentation for this event. Concurrently, we will complete and submit all required documentation, ensuring that the project is thoroughly documented and ready for evaluation. With the semester coming to a close, our focus will remain on wrapping up all deliverables to a high standard.

Accomplishments:

This week, our primary focus was on testing and verification of the system. We conducted detailed measurements of time latency and accuracy, ensuring the system performs as intended under various conditions. My main contribution in this phase was assisting with testing on the controller side, ensuring its functionality and reliability. Additionally, I took on the role of presenter for our final presentation, where I showcased our progress and demonstrated the nearly completed system. These efforts were critical in validating our design and highlighting its capabilities.

Progress:

The project is in a good state, with the system almost fully functional. While there are still minor upgrades to be implemented, the core components have been successfully integrated and are operating effectively. The steady progress has positioned us well for the upcoming final presentation.

Next Steps:

Next week, we will deliver our final presentation and evaluate potential enhancements based on available time. With final exams approaching and everyone’s schedules packed, we aim to prioritize refinements that can provide the greatest value with minimal effort. Our focus will remain on polishing the system to ensure it is ready for the demonstration.

Accomplishments:
This week, I integrated my circuit with the new 3D-printed controller frame. The sensors are now aligned with the human hand-finger configuration, ensuring accurate mapping for control. Additionally, I updated the sensor reading code to operate at a 115200 baud rate. The improved code achieves faster response times, with force changes now distinguishable within approximately 0.1 seconds. Over the weekend, we finalized all the major components of our project. At this point, everything is ready for the demo presentation, marking a significant milestone in our progress.

Progress:
While the progress has not been rapid, it has been efficient, enabling us to meet all deadlines successfully. The project is in a stable state and fully prepared for the upcoming demonstration.

Next Steps:
Next week, we will focus on resolving any remaining issues to further enhance the system. These tasks include adding vibration feedback, redesigning the circuit for improved performance, and refining the controller for better usability. These final adjustments will solidify our system and ensure its success during the demo.

Accomplishments: This week, I rebuilt the circuit after it came off the breadboard, taking the time to label each cluster of lines for clarity and testing the circuit thoroughly. I confirmed that the design is robust and ready for implementation on the controller pipe. Additionally, I collaborated with my team to develop Python code that periodically requests average sensor readings from the board, and the results have been consistently smooth and reliable.

Progress: Everything is progressing on schedule. We should be able to finish everything before demo.

Next Steps: Next week, we will focus on finalizing synchronized tasks and spend extensive time together to ensure that all components integrate seamlessly.

Accomplishments: This week, I addressed two crucial issues in the circuit design. First, I fixed the problem where the circuit would sometimes stop looping when the sensor went out of its working range by setting the board to reset every 5 seconds, ensuring that the loop never stalls for more than 5 seconds. Second, I resolved interference between sensors when one was pressed by implementing P-MOSFETs to make each sensor’s power source independent, preventing cross-voltage interference.

Progress: Fixing these two issues was faster than anticipated, which has significantly advanced the project. Additionally, I built a first draft of a more compact version of the circuit to fit neatly on the controller, transitioning from a breadboard setup. I am on track to complete this streamlined circuit by Sunday.

Accomplishments: This week, I successfully wrote code to interface with the force sensor, averaging the readings from a multi-force sensor setup and ensuring that these readings correlate linearly with the actual force applied.

Progress: The project has been slightly behind schedule, but with recent progress, it will soon be back on track.

Next Steps: Next week, I will receive the PVC pipe, which will serve as the main frame for the controller. I plan to position the force sensors on it and verify that the system continues to function correctly in this new configuration. Additionally, I will assist my teammate with implementing the force sensor on the robotic arm.

Accomplishments This Week: This week, I successfully submitted all of my purchase orders and completed the design report with my team. However, due to traveling during fall break, I wasn’t able to accomplish much beyond these tasks.

Progress Evaluation: Although the purchase orders have been submitted, the TAs raised some questions, and the orders haven’t been placed yet. I expect these concerns to be resolved on Monday, after which the progress should return to normal.

Next Week’s Deliverables: Once the orders are placed, I plan to begin building the actual controller and assembling the components as scheduled. I really wants to get the orders through so we can actually starts to build the whole system,

Accomplishments This Week:
This week, I focused on selecting items for purchase based on the necessary material list. I carefully ensured that each component I chose is in the correct configuration and will be compatible with the parts my teammates have selected.

Progress Evaluation:
My progress is slightly behind schedule due to midterms. The purchase order was supposed to be submitted already, but I plan to complete this task over the weekend. However, I have no more midterms coming up, so I expect to remain on track moving forward.

Next Week’s Deliverables:
Once the items arrive, I will begin building the product and assembling the components as planned.

Accomplishments This Week: This week, I focused on updating the design of the remote controller for the project. I developed and finalized detailed schematics, capturing the design from multiple viewpoints to ensure clarity and thoroughness. I made significant progress in decision-making, finalizing all aspects except for the method to simulate weight, which remains under discussion.

Progress Evaluation: My progress is on schedule, with no significant delays. Although we changed the design of the remote controller a lot, I am moving steadily toward the next project milestones.

Next Week’s Deliverables: For the upcoming week, I plan to start the ordering process with the TA for the decided components. Additionally, I will compile a comprehensive list of material sources available, ensuring that everything necessary for the next phase of the project is accounted for.

This will help maintain the project timeline and ensure steady progress.

This week, We meet to discuss the general design of our robotic hand and remote controller. We also talked about our algorithm in the big picture.

For my work, I finish the schematics draft for the remote controller. There is a PDF uploaded including the schismatic. a simple representation of what information is transmitted between devices, and a one-sentence summary of our algorithm for input data.

The schematic draft represents our final idea of how the remote hand should look. We have several different ideas abandoned along the way to reach this one. The records of previous ideas are not organized. If necessary, I will organize them to upload later.
