Head Servo – 6 volt servo originally designed for missile guidance systems, with direct drive to head
Wing Mechanism – wing servo as above attached to wings with stainless steel rods
Wing Attachment – wings attached to body with brass hinges, machined out to reduce resistance
Light Sensor – ambient light sensor located under tail or in body moulding above legs (earlier models)
Connector – 6 pin connector with weatherproof cover located under tail
Connector Function – allows 6 volt charger to be plugged in or data cable for diagnostics
Speaker grid – grid of small holes under tail to allow sound to pass from internal speaker
Speaker – mylar film type able to operate in all weathers mounted inside the body cavity tail section
Battery – consists of 5 F-Type NiMH cells giving 6 volts and a capacity of 13Ahr
Battery Location – sealed inside leg section of the body cavity and secured with cable ties
Electronics – surface mount electronics with PIC microprocessor controlling servos and sound. There is a 4Mhz ceramic resonator providing the clock signal for the micro. There are no external buses. All power supplies are linear. Electromagnetic radiation emanating from Robop is expected to be very low to undetectable at any distance from the bird.
Voltage – 6 Volts. On the trailer system we supply a 12 Volt 85AHr lead acid leisure battery with regulator to provide 6V.
Current – averages 180mA, maximum stall current 2A (servos)
Run Time – 7 to 10 days with internal battery up to 6 months with external lead acid battery (trailer system)
Dimensions – Height 40cm (16”) including base
Height 36cm (14”) excluding base
Width 20cm (8”)
Length 53 cm (21”)
Wing Span 51cm (20”)
Dimensions Trailer System – Towing length 400 cm (158”)
Towing width 196 cm (55”)
Towing Height 140 cm (77”)
Static length 507cm (200”) fully extended
Height with pole erected 550 cm plus 40 cm for bird
Robop Technical Specification
General Notes
Robop is constructed with modern composite materials and environmentally sealed to allow it to work in all weather conditions in exposed locations. Robop has been used in all British weather conditions and has also been tested in Dubai where the temperature was 40C with 98% humidity. A floating version of Robop has also been tested at sea, although further tests will be necessary to confirm results over an extended period. Robop is sealed and has no user serviceable parts. The internal battery is recharged using the external weatherproof connector. Using an ambient light sensor Robop has been programmed to start at dawn and stop at night. Running time will depend on the season (i.e. number of hours of daylight) and on the prevailing weather conditions, particularly wind speed. Onboard sensors also detect excess current drain due to the wings being frozen or covered with snow. These sensors shut the system down for 2 hours whereupon the start sequence is re tried. Robop is aerodynamic and will turn into the prevailing wind. Robops systems are all low power, low voltage (6V) and apart from the microprocessor clock there are no high frequency components. This results in a system where users should have no concerns about electrical safety or interference with other systems.
Details
Bodyshell, head and Wings – material – GRP (hand laid up)
Feet – material – GRP with additives to give flexibility
Legs – made from steel spring secured to body and feet by bolts
Coating – all GRP parts etched and coated with primer then given multiple coats of polyurethane paint
