I started the design review slides. In order to determine optimal camera positions, I read Two-Phase Algorithm for Optimal Camera Placement and began implementing its algorithm in Python. There is sort of a steep learning curve, since I haven’t had real experience with optimization techniques. I started off using the cvxpy Python framwork, but got stuck when I realised it could not generate binary integer variables of more than 2 dimensions without clever tricks. I am shifting to using the Python API for IBM’s CPLEX solver (available to me through CMU). By using the process described in the paper and experimenting, we should have a camera arrangement that covers a majority of the print bed. In addition, I started on the block diagram/circuit for the power system and finalized the choice in RF module for the WIFI chip.
