Build Session 20

January 31, 2015

Walking is turning out to be pretty difficult. Today our goal was to get to the point of doing a one-leg test using the new force sensitive resistors (FSRs) as our sensing method. We didn’t get quite that far on Saturday, but on Sunday Joseph and Tony did a test that had mixed results. We learn a lot with each test (for instance we’ve learned that FSRs are far better than slide potentiometers), but we’re still not to the point of walking.

Joseph and Cole built the cables to connect the sensors to the control board and they attached the sensors to the mounting bracket that Sammy and Thelonious made:

and then Sammy and Thelonious screwed that to the armature:

Testing the sensor data using the new diagnostic console that reports all sensor readings and valve actuations:

The console has proved extremely useful already, allowing us to very quickly track down problems that would take us hours without it.

Gabriel took the lead on drafting the story of the project that will appear on the landing page of the Kickstarter campaign.
