6	10 April 2020	16 April 2020	Implement basic obstacle avoidance algorithm based on sensor data and test the same. Continue testing motor driver via commands from CAN bus. Build in speed steps to reverse motor for reverse to work correctly. Mount all the sensors and test for any dead band and modify their positions for maximum coverage. Integrate the fusion of LIDAR and Ultrasound sensor to get overall feedback from all the directions. Develop algorithm to avoid obstacles and plan the car's further navigation path. Complete final prototype of the obstacle avoidance feature. Calibrate Compass Module. Develop code for Compass module communication over CAN. 16 April 2019 DEMO: Motors driven by wheel feedback and sensors, Basic obstacle avoidance. Final Wiki Schedule.

Send and receive current location, destination and checkpoint coordinates to and from App and Geo module via BRIDGE. Calibrate sensors readings and work on filtering algorithm with Master & Sensor Begin work on LCD to show vehicle live status(speed, fuel-status, obstacles, distance to destination etc.) in a GUI. Finish implementing speed control on motor (to make sure requested speed is met based on RPM read). Work on Car reversing using Motor Controllers. Integrate all modules with the Master to test the data flow. Validation & Verification of obstacle avoidance, steering logic with rear sensor inputs and reversing. Start incorporating GEO Controller information to Master module Steering logic. Decide, implement and test data exchange between Geo Controller and BRIDGE. Calculate and send simple bearing angle and destination status on CAN to figure out initial challenges. Add a Google Map for setting the car's destination. Send car location to app and check points received to Geo module. Verify the stringent requirement of Start-up Sync, Periodic heart-beat messages. Update Wiki Schedule with Test Reports.
8	24 April 2020	30 April 2020	Testing & Validation of the LCD UI and display run time vehicle status and looking forward for feedback from team if any. Improve & Validate Navigation logic with multiple checkpoints, bearing angle and destination information. Identify and mitigate GPS locking, Location Accuracy and Number of Satellite-In-View coming. Validate Accuracy of Compass Calibration with iPhone Compass. Determine and add DBC Changes and finalized. Implement the steering logic with bearing angle and status provided by GEO-Module. Consistently Communicate current car location to App, get check points from App and relay them to Geo module. Send additional vehicle status information from can bus to the App for display. Send the request to Google for getting the checkpoints(use the Google Maps Directions API). Field test and check for obvious issues in obstacle avoidance, navigation, maintaining speed (up/down hill). Provide feed backs to each team on identified short comings. Update Wiki with new details and information. DEMO: GPS driving
9	1 May 2020	7 May 2020	FIELD TESTING - CRITICAL WEEK Implement turning indicators, break lights and head light. Check for Corner cases for steering logic under various conditions and locations. Analyse field test results for GPS and CMPS and work on it if required. Test the accuracy of check-points from the Blue-tooth controller, location data from the Geo-controller sensor and Navigation Algorithm. Check overall robustness of the complete system. Establish complete connection on PCB Update wiki with details.
10	8 May 2020	21 May 2020	All hands on testing and final bug fixes. Check for tuning or calibration of modules if required. Complete end-to-end testing for various scenarios and conditions. Create the semester long project activity video and upload to YouTube. Update and finalize wiki.
