Current Issues  Wi-Fi Tracking Systems  Infrared Cameras  Required Sensors  Wii Remote  Payload Testing Status  Tasks for this week 

 Wii Remote: MicroCART  Weight close to max payload Weekly Meeting  Triwing Screwdriver needed Agenda to remove outer shell  Current Issues  Payload (and other) testing  Short battery life-need to  Wi-Fi Tracking System acquire new battery.  Infrared Cameras  Contacted Xheli and they are  Required Sensors sold out, recommend no replacement, and will not  Wii Remote have more in stock for 4-6 weeks  Payload Testing Status  Want to make wired power  Tasks for this week delivery systems for long term platform testing.

 Ekahau RTLS MicroCART  Real Time Locating System Weekly Meeting Using 802.11 Agenda  Information Request Sent Out  Current Issues  Best accuracy only within a foot  Wi-Fi Tracking System  Infrared Cameras  Do we want to use an RTLS if we are not going to move far?  Required Sensors  Wii Remote  Payload Testing Status  Tasks for this week

 Are we going to utilize Dr. MicroCART Elia’s system or get our own? Weekly Meeting  If we use the current system we need another camera for Agenda Z-axis  Current Issues  If we make our own there are  Wi-Fi Tracking System a few companies we could  Infrared Cameras buy them from:  Vicon  Required Sensors  Electrophysics  Wii Remote  Payload Testing Status  Do we need any positioning  Tasks for this week system if we use the Wii- Remote??

 Air-based system MicroCART  Helicopter electronics  Microprocessor/board for basic Weekly Meeting stabilization calculations, with a wired/wireless connection to the Agenda helicopter microcontroller or ground station  Current Issues  Gyroscope(s)  Wi-Fi Tracking System  Accelerometer  Some type of positioning system  Infrared Cameras  Camera  IPS (Wi-Fi sensors)  Required Sensors  Wireless Tx/Rx  Battery/converter to power these  Wii Remote electronics  Platform to hold these electronics  Payload Testing Status  EMI shielding?  Tasks for this week  Ground station electronics  Computer with wireless Tx/Rx  Possibly some sort of connection to the helicopter remote control

 Ground-based system MicroCART  Helicopter electronics Weekly Meeting  Gyroscope(s)  Accelerometer Agenda  Some type of positioning system  Current Issues  Camera  Wi-Fi Tracking System  IPS (Wi-Fi sensors)  Wireless Tx/Rx  Infrared Cameras  Battery/converter to power these  Required Sensors electronics  Platform to hold these electronics  Wii Remote  EMI shielding?  Payload Testing Status  Ground station electronics  Computer with wireless Tx/Rx  Tasks for this week  Possibly some sort of connection to the helicopter remote control

 Wii Remote Research MicroCART  Sensors Weekly Meeting  Analog DevicesADXL330: 3 axis- accelerometer Agenda  Infrared sensor strip triangulates position and 2 axis gyration.  Current Issues  Possible add-on: Wii Motion Plus  Wi-Fi Tracking System which has 2 axis gyro (IDG-600)  Physical Structure  Infrared Cameras  Weight with case and no  Required Sensors batteries=80g  Triwing screws hold case  Wii Remote together.  Connection  Payload Testing Status  Broadcom BCM2042 Bluetooth  Tasks for this week  More info at: http://wiibrew.org/wiki/Wiim ote

 “Fixed” quantities MicroCART  Heli. Mass empty 190g  Batt. Mass 50g Weekly Meeting  Flight ready platform: 240g  Wii-mote without battries or batt. Agenda cover: 80g  Current Issues  Weight reductions likely possible  Payload capabilities (so far)  Wi-Fi Tracking System  Absolute max payload: 120g  ^only for a few seconds  Infrared Cameras  Data collected on next slide  Required Sensors  Full report to come  Current findings/conclusions  Wii Remote  Lower throttle tests should hopefully yield more steady (slower decay)  Payload Testing Status results  Replacement/Reference battery(ies)  Tasks for this week would be useful/necessary  Wired power support for flight testing a must due to short flight time with payload and LONG charge time

Mike  MicroCART  Write testing documents for the Wii remote Weekly Meeting  Begin testing Wii remote  Locate/Purchase Tri-wing Agenda screwdriver  Current Issues Kollin   Help Mike with testing the Wii  Wi-Fi Tracking System remote and with formulating the test procedure  Infrared Cameras  Research battery alternatives Matt  Required Sensors   Continue Payload Testing  Wii Remote  Fabricate wire power harness and how to minimize the effects adding  Payload Testing Status such a harness will cause to flight mechanics  Tasks for this week Alex   Continue Payload Testing  Locate power supply with sufficient ranges to power helicopter
