Solutions Pick-and-place or wireless robotOptions Robotic arm, Mitsubishi RH-12SH535, or
- Custom designed robotic arm - Custom Star picker- Snake arm, OC Robotics- Wireless robots, UKATC in-house project
Problems for EAGLE Not enough space due to back-focal distance issue
Mitsubishi RH-12SH535.Gripper reach - 278 to 850mmRepeatability - +/-25 m
Star pickerGripper reach - 450ØmmRepeatability - +/-2m
Placement of POMs and Intermediate Field Mirrors (IFMs)
27
Wireless robotsRange – TBCAccuracy – 3 to 10m expected
Conclusions – More investigation to find ‘of the shelf’ robot to include consultation with manufacturers for specific gripper design requirements- But space restrictions for EAGLE may restrict use of commercial robots Further investigation into wireless solution as the technology develops – PhD project started
Snake Arm RoboticsGripper reach – design dependantRepeatability - 5m difficult but consultation required

Starbugs
Work well!• All orientations• Cryogenic• Non-planar ‘focal
plane’But EAGLE does not
have these requirements, as SmartMOMSI for OWL did!
31
Why develop MAPS?
Is there another way?• Yes - a pick and place module
– (STARPICKER)
But… MAPS would give us: • Lower configuration times.• Potentially very small POM-footprint. • Associated sub systems would require less space.
At the moment the technical readiness of the whole system is
low but the readiness of the component systems is higher
32
Requirements:• x-y drive• Accuracy: ±10 μm• Speed: 10mms-1
• Ability to rotate about z axis
Possible drive mechanism:• Micro brushless d.c. motors.
High speeds, but high power? • Piezoelectric actuators used to form inch worm.
High precision and low power, but low speed?
We have completed a Master’s project thesis from Heriot Watt Robotics department, analysing drive options & friction/torque trade-offs
May need to separate the problem: use x-y drive and then a piezoelectric rotator stage for angular alignment.
Driving Mechanism
33
Telemetry and control
• Are the robots and their mirrors where we want them to be?– Focal plane will be imaged.
• Form a closed-loop positioning system.
– Use LEDs to identify position and distinguish robots.– Tests have shown satisfactory precision can easily be achieved.
• Interface with the robot via a Zigbee wireless link.– Only send commands to robots.
34
Build a proof of concept prototype utilisingexisting technologies.
Building a simple chassis to hold motors circuitry and a simple battery.
PIC microcontroller with pre-programmed patterns.
Set up telemetry system using LEDs and camera as before.
Show how accurate can the x-y drive be with standard dc motors
Aim to complete this year with rapid prototyping & subcontract electronics

Smart Instrument Technologies Proposal for FP7:
Summary
• Smart Focal Plane Technology developments are now being carried forward into ELT instrument Phase A programme for EAGLE and possibly OPTIMOS
• Proposal for FP7 addresses 2 further questions:– How to build lower mass, active instruments to meet
flexure requirements of wide-field or high resolution cryogenic instruments?
• Note that mass/volume constraints for EAGLE & HARMONI result in density <20% of water, compared with > 30% for current instruments
– Are there science and operational gains from expanding the Smart Focal Plane concept into a Smart Instrument Suite where several different instruments a fed from a wide field pick off system, and if so what technologies need development?
46
Objectives in FP7
• Provide instrument builders with a suite of building blocks that will enable a paradigm shift in the way the ground-based astronomical community builds optical and infrared instruments.
• Smart technologies and devices will be developed so that European astronomical instrument builders can meet the demands made by the science community for– wider fields-of-view, – higher spectral and spatial resolutions, – wider bandwidths and – simultaneous spectroscopy of multiple objects
• while fitting within demanding size-footprints, mass budgets and engineering tolerances.
47
E-ELT Instrument Platform
• 9 focal stations– 2 gravity
invariant– 1 Coudé
• How will we deal with the other 6?
• And outside Europe: all the GMT focal stations?
48
Example of closed loop compensation: X-shooter for
VLT
• Requirements:– Stability of 0.08
asec (goal 0.04)
• Challenge– 3 arm UVB/Vis/NIR
(300-2400 nm) spectrograph at Cass
49
Solution: Active Flexure Compensation
• 2 tip-tilt piezo mirrors align 3 slits using pinhole illuminators
• Correct after slew or every hour
Rasmussen et al, SPIE 2008
50
Reducing size and mass will help reduce flexure
• How?– Lightweight and stiff
structural materials– Ultra lightweight metal
optics• ASTRON example
– Integrated Optics devices• Astrophotonics
– More compact optical designs
51
Reduce flexure with more compact instruments
New instrument optics?• Flexure• Extreme aspheres can
produce more compact instruments
• Less flexure as linear dimensions are less - goes as L2
52
Smart Technologies Toolkit
• Active Focal Planes – motor or piezo drives
• Active Structures• Active mirrors• Built-in metrology• Highly Aspheric Mirrors• New materials and
corresponding characterisation data
• Integrated Modelling Tools• Micro spectrometers – see
Jeremy Allington-Smith Astrophotonics
53
Plan
• Develop a novel instrument architecture– drive the requirements of these Smart Instrument building
blocks and then use this to model operational and observing efficiency in the context of a practical instrument
• Develop Smart Instrument Technologies – active mirrors, – micro-actuation – metrology devices.
• In addition, the drive for wider fields-of-view pushes us towards large and heavy instruments, exacerbating the flexure problems, so we will develop – smart structures and – highly aspheric mirrors to enable more compact and lighter
instruments.
54
Work package 5.1: Technical Management and System
Analysis
• A Smart Instrument architecture concept will be developed based on an existing telescope such as the VLT instrument suite– Concept drawn up through a joint team workshop,
then developed by the lead team at the UK ATC• The instrument concept will be evaluated
against existing instruments to assess the improvements in terms of performance, mass, volume and cost
• This concept will then be used to determine the requirements for the technology to be developed
55
Work package 5.2: Optical Components with Extreme Aspheric
Surfaces
• LAM will develop the concept of a highly compact optical design that makes use of extreme aspheric surface optical components– Develop a plug-in design tool that can be used in conjunction
with existing optical analysis software such as Zemax to design, optimise and analyse the performance of extreme aspheric surface optical components.
– Develop and evaluate the manufacturing processes (including stress polishing) required to manufacture these extreme aspheric optical surfaces
– Design and manufacture an optical component demonstrator with extreme aspheric surfaces (in the context of an astronomical instrument for wide field spectroscopy)
– Devise methods to differentiate between low and mid/high order deformations, e.g. combining passive low/mid order deformations and high order active deformations
– Laboratory characterisation of the extreme surface optical component.
– Define the optical requirements of the demonstrator’s extreme surface optical components
56
Work package 5.3: Smart Micro Actuation Devices and Cryogenic
Structures
• Investigate the combination of piezo actuators, miniature motors and miniature optical devices to produce a number of SIT building blocks that can be used in, for example: a moderate speed, low density wavefront compensator to correct for instrument deformation, and thus actively control the stiffness of a structure over a large dynamic range.
• These devices can also be used to position optical components accurately to replace heavy and large structures with dynamic equivalents.
• Evaluation and test of actuation, encoding, measurement and control devices at cryogenic temperatures, down to 20K
• Evaluate optical and dimensional metrology systems used in the growing application of Smart Structures in the aerospace, defence and civil engineering industries– optical sensors (including CCD/CMOS cameras and interferometers)– strain gauges (including fibre devices)– inclinometers.
• Investigate the application of cryogenically cooled extension sensing actuators to maintain open loop nanometre position accuracy for instrumentation applications
• Investigation of bonding of piezo-devices to Zerodur and silicon carbide using silicate bonding.
