Seven images of green rope upright at different angles. Caption: MSRA motion for (a) 40 ∘ , (b) 50 ∘ , (c) 60 ∘ , (d) 0 ∘ in position and orientation control. MSRA motion comparison for the task (e) 50 ∘ a20 ∘ , (f) 50 ∘ , and (g) 50 ∘ c20 ∘ .

Authors propose a planning + control framework for modular #SoftRobot arms that uses biLSTMs and only coarse internal sensing feedback. It handles position & orientation control, obstacle avoidance & online interaction.

Attractions at the stand included demonstrations of soft robotic grippers & walkers, a #SoftRobot flipper, and experiments on #polymers for example with gummy bear slime. We could see the fascination in the eyes of many children, and we experienced how important this insight into #science is. ✨

Sensors allow soft #robots to interact with their environment. These #sensors often rely on electronic components, which increases the systems complexity and reduces robustness.

Falk Tauber and his team at #livMatS developed a #3D-printed, electronics-free sensory system for a #SoftRobot. (1/2)

Amphibious Untethered Inchworm Soft Robot Crawls Fast, Swims

Researchers unveiled an untethered soft robot weighing 102.63 g that crawls at 3.74 cm/s on dry surfaces and swims at 0.82 cm/s, using magnetic actuation and onboard vision. Read more: getnews.me/amphibious-untethered-in... #softrobot #magneticactuation

Magnetically Reprogrammable Soft Robot Offers Five Surgical Functions

A millimeter‑scale soft robot with reprogrammable magnetization can perform five surgical functions and move with full six‑degree‑of‑freedom control using magnetic fields up to ~65 mT. getnews.me/magnetically-reprogramma... #softrobot #surgery

The first experimental validation of model-based robust position control for an underactuated dielectric elastomer #SoftRobot! This shows the controller stabilizing arbitrary configurations despite underactuation & input saturation.

Robot made from pig gelatin biodegrades when no longer needed Pig gelatin can be used to make a robotic arm that safely biodegrades, rather than adding to landfill

An origami-inspired #robot arm made with material from cotton plants and pigs #biodegrades when no longer needed. Such a #SoftRobot could be further developed to carry out #MedicalProcedures inside the body and then pass safely through it. www.newscientist.com/article/2466...

Manta rays inspire faster swimming robots and better water filters Efficient swimming and feeding make the creatures a model for human machines.

With fins like #mantas, a #softrobot created by a team of researchers at #NorthCarolinaStateUniversity and the #UniversityofVirginia improves on a previous model by reaching speeds of 6.8 body lengths per second, nearly double what its predecessor was capable of. arstechnica.com/science/2024...
