  1. STINGRAY – WiFi ROBOT Designer / builder : Alan Stewart

  2. Introduction Experiences • Over 25 years of experince at University of Ottawa • 15 years with University of Ottawa Haz- Mat Team • 10 years with Clarence-Rockland Fire Dept.

  3. New Stingray WiFi Robot • Differential steering using two servo motors, Futaba FP-S148 • Powered by 2 NiCad 1700 mA/h batteries and AC adaptor controlled. Dual in lab battery chargers. • New photo reflector circuit, using Hamamastu photo reflector P5587 with wheel incremental encoders (64 increments for 360 degrees therefore 5.6 degrees per increments • Parallax Ping ultrasonic sonar on rotating motor • DIY Sandbox Hydrogen Wi-Fi with built in webserver • Serial 16x2 LCD display • Arduino Mega 2560 microcontroller • Wireless Network connection SSID : Robolab

  8. Parallax PING Ultrasonic Sensor • Features:• Provides precise, non-contact distance measurements within a 2 cm to 3 m range• Simple start pulse in (40khz)/echo return variable-width ouput• Burst indicator LED shows measurement in progress• 20 mA power consumption• Narrow acceptance angle• 3-pin header makes it easy to connect using a servo extension cable, no soldering required • http://www.parallax.com/StoreSearchResults/tabid/768/txtSearch/ping/List/0/SortField/4/ProductID/92/Default.aspx]\

  9. Serial LCD 16X2 Display • Features: • Embedded PIC 16F88 utilizes onboard UART for greater communication accuracy • Adjustable baud rates of 2400, 4800, 9600 (default), 14400, 19200 and 38400 • Operational Backspace • Greater processing speed at 10MHz • Incoming buffer stores up to 80 characters • Backlight transistor can handle up to 1A • Pulse width modulation of backlight allows direct control of backlight brightness and current consumption • All surface mount design allows a backpack that is half the size of the original • Faster boot-up time • Boot-up display can be turned on/off via firmware • User definable splash screen • http://www.robotshop.com/ca/productinfo.aspx?pc=RB-Spa-333&lang=en-US

  10. Possible add on sensor 8 Pixel Thermal Array Sensor Voltage - 5v only required Current - 5mA Typ. excluding servo Temperature Range - 4°C - 100°C Accuracy (Full FOV) - +/-2°C +/-2% from 10°C to 100°C, Accuracy (Full FOV) - +/-3°C from 4°C to 10°CField of View - 41° x 6° (8 pixels of approx. 5° x 6°) Outputs - 1 ambient + 8 pixel temperatures Communication - I2C Interface Servo - Controls servo in 32 steps to 180° rotation Small Size - 31mm x 18mm Detects a candle flame at a range 2 metres (6ft) and is unaffected by ambient light!
