  • Aerospace Engineering on the Back of an Envelope
    As per Table 2.2 the voltage applied to the driver is supplied by three 12 volt batteries. The solenoid driver is cued by a low (0 to 5 volt) digital control voltage signal supplied � The initiation signal is radioed to the robot from the student team that remotely operates the robot. � APPENDIX: MODELING OF THE TEMPERATURE RISE PRODUCED BY OHMIC HEATING FROM SINGLE OR MULTIPLE SOLENOID- ACTUATOR KICKS .
  • Task-reconfigurable robots: navigators and manipulators
    The actuators for the joints are servomotors de- signed for use in radio controlled aircraft. There are two 12 - volt electromagnets per Inchworm foot, arranged in-line with the body of the Inchworm.

  • Development of localized arc filament RF plasma actuators for high-speed and high Reynolds number flow control
    Assuming that the number of actuators required for efficient flow control scales linearly with jet diameter (note that the flow power scales as diameter squared), controlling a 12 -inch diameter jet would require the use of at least *100 actuators . � after breakdown, the voltage across the arc discharge filament is much lower, typically a few hundred Volts . � Adamovich et al. 2009), we studied the feasibility of the use of pulsed radio frequency (RF) plasma �
  • Remote Controls On A Zero-Turn Commercial Lawn Mower To Conduct SAE J2194 Rollover Tests
    A fail-safe condition was also needed that would drop out the actuator relays and return them � The radio system chosen is a Futaba T9CAP that operates at 75 MHz (see Figure 3). The power for the radio receiver is supplied by the existing 12 volt dc mower battery. The receiver controls the servos located on the mower in the breakout box.
  • Navigating 3D steel web structures with an inchworm robot
    The actuators for the joints are servomotors (Airtronics 94739 Proportional Retract Servo) designed for use in radio controlled air- craft. There are two 12 - volt elec- tromagnets per inchworm foot, arranged in-line with the body of the Inchworm.
  • Radio-controlled models. Radio Section informal lecture, 24th March, 1952
    DISCUSSION ON " RADIO - CONTROLLED MODELS" No relays were used, the actuators being operated directly by the currents in the thermionic-valve circuits � The transmitting equipment dissipated approximately 150 watts, and was designed to operate from a 12 - volt accumulator, although for extended periods of operation a petrol-engine-driven generator could be used.
  • Discussion on �The development of the electrical system on the Bristol Brabazon I Mark I Aircraft� before the North-Western Centre, at Manchester, 8th May, 1951
    I should be very interested in the author's comments on development from this viewpoint, and should also like to hear what provision is made on the Brabazon for the controlled - frequency a.c. supplies required by some radio equipment. � the author's views on the comparative weights of a motor running at, say, 12 000 r.p � Another comparison could be made between electric actuators and hydraulic jacks. For example, in a large military aircraft we are asked to provide 24- volt d.c. with �
  • Discussion on �A dipole with a tuned parasitic radiator�
    DISCUSSION ON " RADIO - CONTROLLED MODELS" No relays were used, the actuators being operated directly by the currents in the thermionic-valve circuits � The transmitting equipment dissipated approximately 150 watts, and was designed to operate from a 12 - volt accumulator, although for extended periods of operation a petrol-engine-driven generator could be used.
  • Converting outdoor vehicles into autonomous mobile robots
    Ignition could be killed by radio controlled servo driving the switch towards the spring or would simply cut out if radio control was lost or servo actuator battery power failed. Current to drive a small 12 volt geared drill DC motor was supplied through the rings via the brushes.
