Fundamental Research Challenges (1)

In Biology • Research challenges in general

– Engineers with limited knowledge of life science and medicine

– Lack of effective tooling and sensing technologies to deal with massive and tiny bio-materials and bio-samples

– New developments in devices and systems are evolutional not revolutionary

• Research challenges in particular– Automated cell handling and operations (probing and

sensing)– Automated protein characterization and functional analysis– Automated protein crystallography - crystallization,

harvesting, x-ray detection– Automated DNA sequencing (still slow)– Automated DNA and protein chip production and analysis

World Technology Evaluation CenterInternational Study of Robotics Research--Supported by NASA, NSF and NIH 14

Fundamental Research Challenges (2)

In Medicine (by Russ Taylor):

• Modeling and analysis: computationally effective methods for patient-specific modeling and analysis.

• Interface technologies: extension of the sensory, motor, and human-adaptation abilities of computer-based systems in a demanding and constrained environment.

• Systems: architectures, building blocks and analysis techniques facilitating rapid development and validation of versatile CIS systems and processes with predicable performance.

Challenging Example (1): Protein Crystal Harvesting

Pieces of protein crystals (pink)Automated picking-up and mounting to the loop for x-ray crystal-graphics

Protein crystal is too small to handle automatically- 3D vision for tiny space is challenging- Picking and placing by machine is extremely difficult if not impossible

Challenging Example (2): Capsular Endoscope

• Application: diagnosis and therapy of gastrointestinal tract of human beings

• Robotic device: an active device which can automatically move in a tubular, compliant and slippery environment

• Need advanced MEMS, electronics, sensing, data storage, communications, autonomous, control, etc. technologies.

Quantitative Observation

• U.S. is leading the world in the numbers of research groups and areas of the research– Hard to dispute at this time

• Many U.S. universities are extremely active in biology research• U.S. industry is more aggressive in commercialization• Produce the demands for robotics and automation for life science

• More countries are joining the group– Quality is also rising (the best paper in cell-handling in ICRA2003

is from Hong Kong)– Some are ahead of U.S. (such as cell handling)

World Technology Evaluation CenterInternational Study of Robotics Research--Supported by NASA, NSF and NIH 28

Qualitative Observation

• For biological applications– Research on robotics and automation in bio-applications is young– Research quality in the U.S. is as good as that in Asia and Europe– Research results vary from laboratory demonstrations to reliable

applications in industry– Research approaches are Ad Hoc (no systematic theory)– Applications heavily rely on the progress of nano and MEMS

technologies– Collaboration between engineering and biology is challenging

• For medical applications– Robotics surgery is leading the world for heart, brain, knee, spinal

cord operations

Summary

• Research on robotics and automation for biological applications is young (less than 10 years)

• U.S. is still leading the world in the numbers of laboratories and industries involved

• U.S. leads the world in identifying new applications• Theory and approaches are ad hoc, not systematic: “evolutionary not

revolutionary” (Meldrum)• There are many opportunities for collaboration between

biologists/doctors and engineers• Biology breakthrough needs revolutionary tools in engineering• The leading position of U.S. is being challenged.
