Abstract Traditional quadruped robots are known for their agile movement and versatility across varied terrains. However, foot structures struggle to navigate unstructured terrains such as pipes, slopes, protrusions. This paper proposes a novel tensegrity structure consisting of ankle joint an X-shaped adaptive footpad, which enhances the terrain adaptability legged robots. The equilibrium equation is established, relationship between translational stiffness spring derived. Additionally, mathematical model number footpad units with deformation height length established. A physical prototype was fabricated using 3D printing. Experiments conducted validate both footpad. results indicate that proposed exhibits good on varying radii, steps, S-curves, spherical surfaces. can enhance environmental has excellent impact resistance effects.

The increasing demand for innovative grippers and actuators the automation sector encourages development of new functional principles. Intelligent materials are particularly suitable this purpose based on their high energy density. In study, a two-finger gripper driven by shape memory alloys (SMA) use in technology is presented. Previous SMA can only be found field micro gripping due to limited stroke generated SMA. Based methodical product development, type was developed presented which achieve an opening width comparable conventional transmission mechanisms. Two different variants shown compared aiming minimize installation space weight gripper. addition design presentation, prototype built, functionality demonstrated through various test series.

Abstract Dual-response can respond to multiple stimuli and overcome the limitations of a single response, especially in biomimetic applications where large deformations high stiffness are demand. This soft gripper fabricated with new multi-section design is novel dual-response actuator that combines silicone magnetic NdFeB particles, highlighting advantages hybrid pneumatic actuation achieve bending behavior efficient at low pressure. The position center section changed by adjusting internal Here, an umbrella-rib-like proposed, inspired process umbrella using deployable foldable mechanisms, joint designed for act like ribs such bend-folding location does not change much on robot different pressures. preparation this grippers provides proficiency wide application medical, industry so on.
