Video Friday: Virtual Cat Petting
The 2021 Computer-Human Interaction conference (CHI) took place this week, in amongst the stereo smelling and tooth control were some incredibly creative robotics projects, like this “HairTouch” system that uses robotic manipulation to achieve a variety of haptic sensations using hair.
We propose a pinbased handheld device, HairTouch, to provide stiffness differences, roughness differences, surface height differences and their combinations. HairTouch consists of two pins for the two finger segments close to the index fingertip, respectively. By controlling brush hairs’ length and bending direction to change the hairs’ elasticity and hair tip direction, each pin renders various stiffness and roughness, respectively.

Here’s another cool thing from CHI: a “Pneumatic Raspberry Pi for Soft Robotics.”
FlowIO is a miniature, modular, pneumatic development platform with a software toolkit for control, actuation, and sensing of soft robots and programmable materials. Five pneumatic ports and multiple fully-integrated modules to satisfy various pressure, flow, and size requirements make FlowIO suitable for most wearable and non-wearable pneumatic applications in HCI and soft robotics.

NASA’s Ingenuity Mars Helicopter completed its fifth flight with a one-way journey from Wright Brothers Field to a new airfield 423 feet (129 meters) to the south on May 7, 2021.
NASA has 3D-ified Ingenuity’s third flight, so dig up your 3D glasses and check it out:

Until we can find a good way of training cats, we’ll have to make due with robots if we want to study their neuromuscular dynamics.
Toyoaki Tanikawa and his supervisors assistant professor Yoichi Masuda and Prof Masato Ishikawa developed a four-legged robot that enables the reproduction of motor control of animals using computers. This quadruped robot, which comprises highly back-drivable legs to reproduce the flexibility of animals and torque-controllable motors, can reproduce muscle characteristics of animals. Thus, it is possible to conduct various experiments using this robot instead of the animals themselves.

A team led by Assistant Professor Benjamin Tee from the National University of Singapore has developed a smart material known as AiFoam that could give machines human-like sense of touch, to better judge human intentions and respond to changes in the environment.

Boston University mechanical engineers have developed a unique way to use an ancient Japanese art form for a very 21st-century purpose. In a paper published this week in Science Robotics, Douglas Holmes and BU PhD student Yi Yang demonstrate how they were inspired by kirigami, the traditional Japanese art of paper cutting (cousin of origami paper-folding art), to design soft robotic grippers.

Turns out, if you give robots voices and names and googly eyes and blogs (?), people will try to anthropomorphize them. Go figure!

Domestic garbage management is an important aspect of a sustainable environment. This paper presents a novel garbage classification and localization system for grasping and placement in the correct recycling bin, integrated on a mobile manipulator. In particular, we first introduce and train a deep neural network (namely, GarbageNet) to detect different recyclable types of garbage in the wild. Secondly, we use a grasp localization method to identify the grasp poses of garbage that need to be collected from the ground. Finally, we perform grasping and sorting of the objects by the mobile robot through a whole-body control framework.

We propose a novel robotic system that can improve its semantic perception during deployment. Our system tightly couples multi-sensor perception and localisation to continuously learn from self-supervised pseudo labels.

Pepper is here to offer a “phygital” experience to shoppers.
I had to look up “phygital,” and it’s a combination of phyiscal and digital that is used exclusively in marketing, as far as I can tell, so let us never speak of it again.

Researchers conduct early mobility testing on an engineering model of NASA’s Volatiles Investigating Polar Exploration Rover, or VIPER, and fine-tune a newly installed OptiTrack motion tracking camera system at NASA Glenn’s Simulated Lunar Operations Lab.

Mmm, sorting is satisfying to watch.

iRobot seems to be hiring, although you’ll have to brave a pupper infestation.
Clean floors, though!

Shadow Robot’s bimanual teleoperation system is now commercially available for a price you almost certainly cannot afford!
Converge Robotics Group offers a haptic option, too.
