Personal Progress
Our original plan of utilizing the RealSense Depth Camera L515 that the school already had fell through because after some testing, we found out the L515 Camera’s depth perception range gets severely hindered by sunlight (down to max depth range of 1.5m away). This lead me to do research for new hardware that fits our need. We settled with the RealSense Depth Camera D455 because it has a 6m range in sunlight and from a vender that we know we can trust and has good documentations. However the D455 is pretty pricey so we double checked our hardware needed to build our motorized blind to make sure it all fits within budget. I was able to get it down to all fit within the budget with $100 still available as leeway.
We also collected data to test our Light Area of Effect (LAoE) algorithm on Wednesday. The predicted light area from our LAoE is about 10% off from the actual area the sunlight affected. This is expected since our LAoE algorithm simplifies light to be a particle and thus move in a straight line when in reality light is both a particle and wave and thus would bend outwards a little.
While I am waiting for the hardware purchase to be approved and to arrive, I helped with the design presentation and design report.
We are ahead of schedule because we originally schedule work to began after design presentation so all the work we are doing now were work planned for the coming week.
Classes knowledge utilized
For this weeks work, I’ve utilized knowledge from 18220 to understand the circuit diagram of other arduino controlled motorized blinds.
Plans for Next Week
If we were able to obtain the new RealSense Depth Camera D455 and the hardware for the blinds within the next week, I would be working on setting it up. During the downtimes, I would continue assisting Elizabeth and Dianne with their work.
