Progress Report 4 (1/30/19)
Jan. 29, 2019—Previous Goals Our goals from our last progress report to this point included the following: We needed to finalize purchase orders for the hardware to be used in our project (such as the Myoware sensors, Arduino, and Teensy board). Additionally, we were to find contacts at Ottobock to determine how to proceed with repairing our...
Initial PID Behavior Observation MatLab Code
Jan. 29, 2019—Matlab Code used for initial PID behavior observation. Several different constants and graphical outputs were observed with a step function to see how the controller outputs would change with time. Will be used if Matlab communication with teensy board is made available through Matlab features Useful information regarding MatLab to arduino transformation: https://www.mathworks.com/help/supportpkg/arduinoio/getting-started-with-matlab-support-package-for-arduino-hardware.html % PID...
Weekly Meeting 7 (1/28/19)
Jan. 28, 2019—Ottobock hand – moving forward: Shaan received a contact for “professional services” Kevin Kelly — Case contact Emily is going to email him and cc Shaan They have another hand, just would require an extra component (a post) Presentation Natural muscle control slide – shows 3 key features Sensory motor control might be better term...
Weekly Meeting 6 (1/21/19)
Jan. 21, 2019—Hardware Sponsor has gotten product serviced before by Ottobock Forward her any emails from OB and follow up about contacts she’s used for servicing in the past 3D printing job should be done by tomorrow Algorithm Updates on conversation with Dr. Withrow: Algorithm = EMG differential: only 2 EMGs, but the Myoware does pre-processing...

GANTT Chart Progression
Jan. 19, 2019—Links to GANTT charts showing project design plan progression: Preliminary GANTT chart (11-14) Updated GANTT chart (1-17) Final GANTT chart (4-03)
Weekly Meeting 5 (1/14/19)
Jan. 14, 2019—Hardware Shaan called Ottobock Even on the highest settings, there isn’t enough gain for the arm to contract Everything else seems to be working Will call them back today Advice from Emily May not be enough current to drive it Might be a power issue Try hocking battery supply straight to electrodes Should check with...
