Saferdrill: Control Architecture of a Walking and Climbing Robot Giorgio Pezzuto D’Appolonia Spa (Italy)Jeremi Gancet Space Applications Services N.V. (Belgium) Samir Nabulsi IAI-CSIC (Spain) http://www.dappolonia-research.com/saferdrill RISE’08 Workshop
A few words of acknowledgment… SAFERDRILL is a EU funded project where cooperated the following partners... Roberto Zannini Consolidamento SAFERDRILL is the evolution of EU Roboclimber project, developed also with the support of ESA TTP programme RISE’08 Workshop
Outline • Introduction and context of Saferdrill • Control architecture: big picture • Onboard control and gait strategies • Remote control • Conclusion and perspectives RISE’08 Workshop
1. Introduction and context of Saferdrill Saferdrill motivations: • Aim: cliffs consolidation • Assets: • Reduces human exposition to danger • Reduces environmental impact • Reduces cost and time to perform operations (to be confirmed!) Saferdrill in a few numbers: • 4 legs, 2 ropes walking & climbing robot • 3 tons, car size • 20 meters deep holes drilling RISE’08 Workshop
Power generator Robotic Unit Navigation Onboard Electric Panel Engine/pumps Valves/sensors Ground Electric Panel 380 V Single Control Unit Wifi access point 220 V TM/TC Remote Control Tablet-PC Wifi antenna Rucksack with power cells Control board Control panel 12 V 2. Control architecture: big picture RISE’08 Workshop
3. Onboard control and gait strategies Control unit => starts / stops engines, pumps and hydraulic valves => read and format signal from sensors and video camera => implements a server for TM production and TC requests reception => PID control RISE’08 Workshop
3. Onboard control and gait strategies Gait strategies => Walking gait: => Climbing gait: => Coordinated with ropes tensioning Always at least 3 legs in contact with the ground Sometimes, 2 legs only in contact with the cliff RISE’08 Workshop
4. Remote control Remote control components: => Hard case => Control panel and electronics => Tablet-PC => Power cells (rucksack) Control board (RCU): => EEPROM based => 32 channels for digital OUT => 80 channels for digital IN => serial connection to the tablet-PC RISE’08 Workshop
4. Remote control Tablet-PC software: RISE’08 Workshop
4. Remote control Tablet-PC GUI prototype: Moving mode Drilling mode RISE’08 Workshop
4. Remote control Tablet-PC commands and LED activation tuning: LED activation edition Command edition RISE’08 Workshop
5. Conclusion and perspectives Conclusion => Remote monitoring and control approach offers a flexible way to define and tune control elements’ behaviors => First laboratory and field tests show a ~20% reduction in the time needed for operations, compared to non-robotic operations => Field tests confirmed the feasibility of remotely control and monitor the cliff consolidation process with Saferdrill RISE’08 Workshop
5. Conclusions and perspectives Perspectives => Navigation module: 3D stereo bench development, integration and testing in progress => Geological interpretation module => Further pre-industrialization of the Saferdrill prototype is ongoing RISE’08 Workshop
