This week I modified the platform jack to allow a motor to rotate the screw. This is necessary because the motor must be stationary while it rotates the head of the screw. Before the modification, the screw head moved when you rotated it because the threaded hole it was inside of caused translation. To fix this, I sanded down part of the screw with a file so the threaded hole no causes linear motion of the screw. Below is an image of the sanded screw.
I also began setting up the neural network infrastructure for posture detection. I selected a google colab notebook that is great for general purpose neural nets and has handy graphing functions to check for overfitting.
In the next week I will begin data collection so by interim demo we will have a coarse posture detector.
