We designed & built the control & drive system for the Batman "Tumbler" roof opening (top left, top right pictures). The entire control system was a single box containing the control system and 3 x servo drives in order to precisely control the positioning of each axis.

General Purpose Processors: We have produced some multi-purpose processor modules, with on board LCD drive, RS485/232 comms (2+ channels available), CAN, and multiple IO. They have been used in the following projects:
-  Data conversion system for London Olympics 2012 (Preston FIZ to ethernet) - Takes in Preston data packets (125Kbps, 9-bit) and sends out "standard" data packets (115Kbps, 8-bit) to an ethernet link. At the other end, it takes in the "standard" packets, and re-assembles them into "Preston" packets for the Preston MDR-2, allowing control of the lens motors.
-  TV Camera Remote Lens Control System (Fuji/Canon)
-  Analogue to Quadrature Converter - Takes in 3 x analogue signals from a joystick etc and converts this to Quad pulses (encoder pulses) or step/direction at 16-bit resolution.
-  Camera Lifting Rig - Converts Preston FIZ position (125Kbps, 9-bit) and converts it to standard data (115Kbps, 8-bit) for input to an "off the shelf" motor controller.
-  Hydraulic Record / Replay System (Peter Pan movie) - Allows live or repeat moves for single-axis hydraulic drive or CAN controlled stepper. Moves can be saved to PC for later use.









Stills Camera Control Systems
-
A one-box solution to control 13 EOS stills cameras providing 13 power supplies, 13 opto-isolated focus/shutter triggers, and a 13 way USB3 hub. It has turned 15 boxes and 54 cables into 1 box and 14 cables.
We have made 72 of these boxes, totalling 936 cameras. We have recently added mautomatic multiple exposure processors to allow various different types of "chase firing" with no added cables. Unique identities for different placement of cameras & flashes has been used. We can now achieve a 5-sequence shoot (involving 5Ds, 6D, 100D, 750D & 600D cameras - all used in each of the 5 shots) in under 700mS. A competitor manages this in only 7 seconds.




Remote Head Control System
- complete head/desk control with 3 x RS482/232 isolated comms channels each end, and CAN control of motor drives, Canon/Fujinon lens control.
Left: desk main control PCB, and smaller header PCB with haptic vibration motor, USB. Rright: head conbtrol PCB, PSU board under the rear, and drive unit for pan motor.

Helicopter Power Monitor -  provides readouts of system voltage, current use, and running time (middle left & right pictures). It  also displays the minimum voltage level reached, and the maximum current draw reached since switch-on (for further information, contact Aerospace Design Facilities).

Helicopter Generator Failure Power Control - We have recently undertaken the redesign of a power switching unit (for Aerospace Design Facilities / AS Aero) which will switch off non-critical power systems in the event of a generator failure.
