In the past week I have been testing the detection ranges of the range sensor. I ran multiple instances of 2 experiments. The first experiment measures the accuracy of range sensor outputs from a known distance from the wall. This experiment was run multiple times by varying the distance from the wall and logging the sensor outputs to a spreadsheet. The 2nd experiment varies the angle that the sensor points at an object. I varied the angle from 3 degrees…
This week, during our meetings, we have discussed and planned for methods of integration for week 9 and 10. Everyone in the team has made substantial progress in their individual components. Zeyi has finished the majority of basic functions of the User Interface for our website. The intergration portion would be intergrating to Zehong’s algorithm to calculate the most optimal path and planned path given by the algorithm. A more detailed description of Zeyi’s progress is in his weekly report….
This week, I finished implementing the entire path planning algorithm. It takes in two inputs, an origin and a list of nodes the cart needs to visit; and it returns the optimal route. As promised, the algorithm pre-computes the shortest distance between each path of nodes in the map using A* with the heuristic function being the euclidean distance between the two nodes. The shortest paths between each path of nodes are stored in data structure to be used in…
Finish some basic functions of the User Interface. User can add or deduct the number of items from the first page, and click submit to save the data in the local database (which Zehong’s algorithm will read and calculate the optimal path). The second page is currently a dummy, to demo that the User Interface can jumps to the second page after clicking the submit button. The display of current & next item and the planned path will be implemented…
