156B Week 3

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

Overall we have finished one arm of the Trifinger and also is 90% completed at fabricating the bases. We also talked to our sponsors to get a more in-depth idea of how the Tri-finger is going to be used in the lab. We aim to connect the arms to the base and stress-test it before getting new parts to building the second and third arm by the end of the week.

Accomplishments from Previous Week

• Fabricated and tested one arm when it is not connected to the base.

• Fixed 3D printer printing with curling error.

• Started applying the Inverse Kinematics to the Arduino.

• 90% Fabricated the base of the Trifinger Robot.

• Finished sorting out and assembling the entire Trifinger Robot.

Goals for This Week (list names after each item). Use specific and measurable objectives.

• Finish fabricating the base of the Trifinger Robot. (Sebastian)

• Stress test the arm to move the Trifinger Robot at the most torque. (Sebastian)

• Printing and fabricating the base_frame of the Trifinger robot. (Joseph)

• Apply Inverse Kinematics to Arduino (Jonathan)

• Sort out the remaining parts needed to purchase to create Arm 2 and Arm 3. (Dustin)

• Start creating the Dynamics Analysis of the Vertical, Horizontal, and Diagonal arms.

• Finish the required Lab Report :

  • Impact on Society

  • Professional Responsibility

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate the date of comments and if via email or in-person)

• 01/12/21 - For 3D print to stop curling, increase bed temperatures, create an enclosure for the 3D printer

• 01/12/21 - To 3D print large models - sent printing files to Chris

• 01/12/21 - For Arduino to Matlab data transmission - Contacted Matthew for a meeting

Risks and Areas of Concern:

• The data transmission rate for Arduino to Matlab

• Possible stress test in practice does not match theoretical calculations

Budget

• TECBEARS PLA for 3D Printing - $40.99

• Timing gear and Belt - $13.99
