3 Project Goal: Build a RC car platform controlled remotely with intuitive controls and visual feedback that can be expanded to demonstrate Controls to college students. The project needs to be captivating and able to demonstrate multidisciplinary engineering innovation at various RIT events this year and into the future. Deliverables: 1. RC Car Platform with Cameras and Sensors 2. Driving Station with Controller 3. Equation of Motion of the System 4. Characterizing Parameters of the System 5. Source Code for Low Level Processing 6. Interface for Student Coding 7. Preliminary Differential Drive Code 8. Supporting Documentation 3RC Camera Car SDR

4 Customer: Dr. Juan Cockburn Controls Professor, RIT, Computer Engineering (CE) Sponsors: RIT CE Department, Multidisciplinary Senior Design (MSD) Freescale Semiconductor RIT FMS (Chris Furnare and Jim Shuffield) RIT ME Department (Bill Finch) Event Attendees: Imagine RIT, Freescale Cup 2014 Various Campus Symposiums and Workshops MSD Team Future RIT MSD Teams / Prospective Students 4RC Camera Car DDR

5 Ready Made RC LLC – Ohio – US Custom 5.8 FPV Starter Package: $ RMRC-420XV NTSC CCD Camera ImmersionRC 600mW 5.8GHz Video Transmitter Uno GHz Receiver Standard Whip Antennas 2 x RMRC 1100mAh Batteries LiPo Charger and Voltage Level Indicator Amazon: $37.26 RC Camera Car DDR5

6 Total Budget Min. Projected Remaining Expenses $ Course Materials, Assorted Extras On Target: $ Total to be Spent Long Lead Time Items Ordered at Minimum Cost Approximately $ Spent Thus Far Approximately $ in Total Value of Parts Student Donated ~$170 Freescale Donation ~$600 Caster City Donation ~$60 FMS / Free Items ~$80 ME Dept. Donation - Free Computer, Table Surfaces ~$50 RC Camera Car DDR6

7 Camera runtime estimated at ~4 hrs 2 LiPo Batteries coming for camera which can be one off one on charging Far exceeds specs Car runtime estimated at ~4 hrs Additional NiMH battery available from CE Department Far exceeds specs RC Camera Car DDR7

8 DDR Weight Analysis Components weighed and values for those not purchased tabulated <10% More than 2013 RIT Freescale Cup Car 20% Less than when car tested for performance (batteries weight will be less on final product) Car will be able to move all the necessary components without issue RC Camera Car DDR8

9 Scale CAD model made of car electronics layout to verify that everything will fit Significant room for expandability RC Camera Car DDR9

10 Performance Testing Car tested with RC controls + Arduino taking encoder data and transmitting back to laptop through Xbees Car run with two RC batteries (high weight) and car easily made it over Freescale bump Gathered performance data that compared favorably with metrics Information gained on bumper functionality, drivability, and clearance RC Camera Car DDR10

11 RC Camera Car DDR11

12 Accelerometers unrealistic for linear speed measurement Linear speed of car to be determined by averaging left and right wheel speeds Used as reference for feedback loop Easily available data for Simulink Possible integration into console display RC Camera Car DDR12

13 Detailed Engineering Requirements Preliminary Testing Results: 0 to Max Speed2.8s Max Speed to 02.4s Max Speed10ft/s Max Range141 ft Addressed Items: Dashboard Indicators Dedicated Computer for Project 13RC Camera Car DDR

14 Freescale automotive division MC9S12HY64 instrument cluster demo board donated for project Stand built for protection and viewing RC Camera Car DDR14 Movement!

15 Console updated with lower mounting height difference between chair and table base Changed to moving table toward user for safety Found better desk and base surface RC Camera Car DDR15

16 Temporarily mounting casters and screen New casters to be expected near start of MSD II Possible seat belt for authenticity, time depending Possible seat plate with team information RC Camera Car DDR16

17 New bumper design made with driving feedback (protection) Polyethylene foam cut using hot wire foam cutter RC Camera Car DDR17

18 MBED functionality with Xbees and MATLAB for KL25Z Freedom Board confirmed RC Camera Car DDR18 Freedom Board, Xbee, Accelerometer, MATLAB Testing

19 Serial information can be directly imported / exported from Simulink model This will be integrated with Brians model to output motor speed signal Simple interface for students to program RC Camera Car DDR19 13b/instrument/srcblkparam.gif

20 Access hatch added to allow for quicker electrical work and internal component mounting KL25Z board mounted inside and wires connected to board outputs for interfacing with board RC Camera Car DDR20

21 Change of approach on console side to controller and Xbees communicating directly with computer Simulink running controls application on computer with serial in/out communication Need for dedicated computer for project to reduce program version issues and increase robustness of final deliverable RC Camera Car DDR21

22 Using TLC Motor Shield on KL25Z Replacing pin headers on motor shield with through pin headers to access unused pins Attaching Xbee and encoder circuits using a perfboard shield on top of motor shield Use existing switches, potentiometers, LEDs, and servo outputs as necessary RC Camera Car DDR22
