Small robots for drug transportation, environmental detection and military reconnaissance have been a popular research topic in the field of robotics. Recently, people have proposed using light-driven actuators to make flexible and remote-controllable small robots. Herein, we reviewed the research on light-driven soft robots in recent years. First, we summarized and compared the performance and fabrication method of light-driven actuators. Then, we classified and summarized the structures of robots according to their move mode. After that, we described how to control the robot. Finally, the challenges of light-driven robots are discussed.

“…Electrically responsive polymer-based actuators have received continuous attention from their ability to respond and convert the external electrical stimulus into controllable mechanical actuation by changing their reversible rigidity and shape [1,2]. In particular, the past few years have seen the rapid emergence of various biobased polymers as the eco-friendly substitutes used for various biomedical devices and biomimetic actuators [3][4][5].…”

Carbon-based electromechanical actuators, capable of reversible shape changes in response to electrical stimuli, have found many potential utilizations such as robotic artificial muscles, micro-pumps, and sensitive switches. In this work, electroactive materials based on the dibutyl phathalate (DBP) plasticized poly (lactic acid) (PLA) and fullerene (C60) were produced by a simple solvent casting method. The PLA composites exhibited fast and reversible responses under electrical stimulus. The highest storage modulus response was obtained from the 1.0%v/v C60/PLA/DBP at 23.51 ×105 Pa under the 1.5 kV/mm electric field. In the bending experiment, the PLA composites bended towards the anode from the attractive force between the negative charges of the induced dipole moments namely the carbonyl groups in PLA and DBP and the π-conjugated electrons of C60 and the positive electrode. The C60/PLA/DBP composite with a small C60 content (0.1%v/v) yielded the maximum bending distance of about 6.0 mm within 10 s and the highest dielectrophoresis force of 1.01 mN at 550 V/mm. Thus, the electrically responsive PLA composites fabricated here with the short response time and high bending deformation are demonstrated here to be promising biobased materials towards actuator applications.

“…These molecules are called organic-inorganic hybrids since they are made up of inorganic cores (Si) and organic groups [ 15 ]. Considering the properties of these cubic compounds in recent years, great attention has been paid to these POSS compounds in technology and science [ 16 , 17 ]. The main properties of these POSS compounds are biocompatibility, non-toxicity, high thermal and mechanical stability, as well as their surface properties, which allow them to be used in making polymers and copolymers by forming a bond between them and polymers such as Poly (Ɛ-caprolactone) (PCL), Polyethylene Glycol (PEG), Polylactic Acid (PLA), etc.…”

Background According to recent studies, electrospun Poly (Ɛ-caprolactone) (PCL) is an absorbing candidate for the formulation of biocompatible scaffolds used in tissue engineering. Tissue engineering is a set of techniques for producing or reconstructing tissue, whose primary purpose is to restore or improve the function of tissues in the human body. Tissue engineering combines the principles of materials and cell transplantation to develop alternative tissues or promote endogenous regeneration. However, this electrospun scaffold, consisting of PCL, has disadvantages such as low cell adhesion, inactivity of the surface, osteoinduction, and acidic destruction of the scaffold that causes inflammation at the implant site, often making it unsuitable implant. This study aimed to improve PCL base cellular scaffolds with the formulation of polyhedral oligomeric silsesquioxane – Polycaprolactone (POSS-PCL) nanofiber scaffolds. The present research focuses on the synthesis of nanofibers for their cell interaction features, and application in bone tissue engineering and regeneration. Results POSS/ PCL Nanocomposites with 2, 5, and 10 wt.% of POSS were synthesized in the Trichloromethane, then POSS – PCL Nanofibers were prepared by the electrospinning technique. In this study, the structures of nanohybrids and nanofibers have been evaluated by FTIR, HNMR, XRD, SEM, EDX, and DSC. The biocompatibility of formulated POSS-PCL scaffolds was detected using mesenchymal stem cells (MSCs). Then several parameters were examined, involving DCFH ROS detection system, gene expression (cell viability/apoptosis, osteogenesis potentiality, and redox molecular homeostasis. Conclusions Based on our results, POSS-PCL nano-scaffolds in comparison with PCL have shown a robust potentiality in homing, growth, and differentiation of stem cells. Graphical Abstract Synthesis of POSS-PCL Nanofibers and their potential application in Bone Regeneration.
