24h operation over 7 days -> NO ACCESS
• No way to do visual checks without cutting the beam• no beam cut shorter than one hour
• Heating time of the SR equipment• Thermal stabilization time on beamlines optical elements• Etc…

Aging hardware -> Potential problems
• Water alarms (pipes radiation damage)• Fire alarms (smoke, hot points…)• Temperature alarms (hot point due to beam)• Motor blocking (mechanical obstacle)• ….

Alarm occurrence: Is it a severe problem ?
• Small leak: we can wait and prepare an intervention at an adequate time.
• Big problem: it is better to prepare the intervention before cutting the beam
• Anyway, we have to cut the beam to check!

ESRF major constraints
• Should stay alive without human intervention for one week • automatic recharging system
• Long travelling path (200m) • Should be fast enough
• Narrow path (90 cm)• Need several point of view for pan/tilt/zoom camera
• movable arm• MTBF should be higher than Storage Ring!• High level of radiation
• Shielding = 20Kg minimum for lead!

Learn from experience• Manual joystick remote operation is not sufficient
• WiFi coverage sometimes weak• Video transmission freezing -> unsecure situation• Very long travel become tedious.
• We need far more than a remote operated car, • The vehicle should be able to go to destination autonomously• If WiFi interrupted-> Continue until target position reached• Should take the best decision in case of unforeseen situation
• Reliability is a real issue…• Autonomy for at least one week.
• Shielding missing, ->, +20Kg payload -> not possible on many devices
• Limited facilities for localization• No GPS, No active transponders, should learn form environment.
• Need to be modular and extensible• Infrared camera, radiation measurement etc…Icalepcs09 October 12 - 16 2009 Kobe, Japan

We do not have the necessary competences->Collaborative project
• Found a partner with high level of expertise in robotics
• Artificial intelligence, Virtual reality• Remote handling• Intelligency of mobile machine• Mechanical design• Is building a robot for ITER
• Interdiciplinarity, cooperation industry, • technology transfer• The Target: Building a tool that can be reproduced and
used in other institutes.

Conclusions
• We are close to the first operational prototype.
• Our aim is to have LabRat as a standard industrial product
• Some R&D efforts still needed• Possibility to obtain some public R&D funding from Finland• For adjusting LabRat to synchtrotrons’ needs, R&D project
Looking for synchrotrons willing to test the product and partner in the development
