Manipulation and Assembly of Particles Using Acoustic Field Gradient and Electromagnetic Needle
Aalto University, School of Electrical Engineering1
Robotic instruments are miniature robots and mechatronic systems that can manipulate small objects and precisely interact with different surfaces. In this talk, I will discuss our recent work in robotic instruments for manipulation and assembly using two techniques: 1) acoustic manipulation devices that can automatically manipulate/assembly a large amount of particles on a surface using the field gradient generated by a single acoustic transducer, both in ambient air and submerged; 2) robotic electromagnetic needle that can precisely extract and independently manipulate/assemble magnetic microparticles in the presence of neighboring magnetic particles by contact or contactless.
