Origami structures have a wide range of applications in robotics and have been intensively investigated by researchers in recent years.However, enabling sub-millimeter structures is an open question especially because of the lack of small enough joints. In this paper, compliant joints made of Silica
Current digital microrobots are mainly composed of bistable modules and flexible structures. Unlike conventional microrobots, they are based on mechanical stability instead of complex control strategies in order to reach precise and repeatable discrete positioning. By design, their number of stable
Recently, micro-assembly of individual photonic elements has been highly attracting to provide new optical functionalities and products with high performances. This approach requires position control in free space and contact detection in constrained space. In both cases, getting accurate measuremen
Micro-assembly using glue is an industrial need, but at the microscale, the gluing process appears highly challenging. Especially when the thickness of the glue film is large relative to the size of components to be assembled. Moreover, the down-scaling of passive techniques used at the macroscale (
This letter presents a displacement self-sensing method for piezoelectric actuators that takes into account the effect of the deformation of these latter on their electrical impedance. A self-updating digital electrical impedance equivalent to that of the piezoelement is suggested in order to overco
High positioning accuracy is a crucial need to perform successfully complex tasks such as micromanipulation and microassembly. This especially enables to provide high performances or to propose new functionalities/products, notably for integrated optical devices. The objective of the letter is to al
Microassembly represents a very promising solution to microproducts and complex Micro-Electro-Mechanical Systems (MEMS) fabrication. Since, in the case of teleoperated assembly, an operator is the main source of errors, there is a great interest in microassembly automation. Its main issue consists i…
