Miniature soft robot with magnetically reprogrammable surgical functions
Miniature robots are untethered actuators, which have significant potential to make existing minimally invasive surgery considerably safer and painless, and enable unprecedented treatments because they are much smaller and dexterous than existing surgical robots. Of the miniature robots, the magnetically actuated ones are the most functional and dexterous. However, existing magnetic miniature robots are currently impractical for surgery because they are either restricted to possessing at most t…

Efficient Detection of Objects Near a Robot Manipulator via Miniature Time-of-Flight Sensors
We provide a method for detecting and localizing objects near a robot arm using arm-mounted miniature time-of-flight sensors. A key challenge when using arm-mounted sensors is differentiating between the robot itself and external objects in sensor measurements. To address this challenge, we propose a computationally lightweight method which utilizes the raw time-of-flight information captured by many off-the-shelf, low-resolution time-of-flight sensor. We build an empirical model of expected se…

BepiColombo at Mercury: Three flybys, three magnetospheres
We examine the first three BepiColombo Mercury flybys Using data from the Miniature Ion Precipitation Analyzer (MIPA), an ion mass analyzer in the Search for Exospheric Refilling and Natural Abundances (SERENA) package on the Mercury Planetary Orbiter (MPO) designed to study magnetospheric dynamics. These flybys all passed from dusk to dawn through the nightside equatorial region but were noticeably different from each other. In the first flyby, we observe a low latitude boundary layer and $\si…

Optimized scintillation configuration for IMPISH hard x-ray detection
The Integrating Miniature Piggyback for Impulsive Solar Hard X-rays (IMPISH) is a solar X-ray spectrometer that features large-area scintillators, fast readout electronics, and good energy resolution in the hard X-ray band. IMPISH is a low-cost spectrometer designed to measure subsecond variation in hard X-ray time profiles from solar flares, with the goal of constraining particle acceleration timescales. To meet these requirements, we carried out a systematic optimization of the scintillation …

Lightweight Tracking Control for Computationally Constrained Aerial Systems with the Newton-Raphson Method
We investigate the performance of a lightweight tracking controller, based on a flow version of the Newton-Raphson method, applied to a miniature blimp and a mid-size quadrotor. This tracking technique has been shown to enjoy theoretical guarantees of performance and has been applied with success in simulation studies and on mobile robots with simple motion models. This paper investigates the technique through real-world flight experiments on aerial hardware platforms subject to realistic deplo…

Demonstrating Visual Information Manipulation Attacks in Augmented Reality: A Hands-On Miniature City-Based Setup
Augmented reality (AR) enhances user interaction with the real world but also presents vulnerabilities, particularly through Visual Information Manipulation (VIM) attacks. These attacks alter important real-world visual cues, leading to user confusion and misdirected actions. In this demo, we present a hands-on experience using a miniature city setup, where users interact with manipulated AR content via the Meta Quest 3. The demo highlights the impact of VIM attacks on user decision-making and …

The Integrating Miniature Piggyback for Impulsive Solar Hard X-rays (IMPISH): a spectrometer for the GRIPS-2 balloon campaign
The Integrating Miniature Piggyback for Impulsive Solar Hard X-rays (IMPISH) is a piggyback mission originally designed for the second flight of the Gamma-Ray Imager/Polarimeter for Solar flares (GRIPS-2) Antarctic balloon. IMPISH will take measurements of collimated, full-Sun X-ray spectra with the goal of detecting sub-second variations (order of tens of milliseconds) of nonthermal X-ray emission during the impulsive phase of large solar flares to probe particle acceleration mechanisms driven…

A miniature EV charger. I love the attention to detail, such as the yellow collision protection, true to life.

This detailed behind-the-scenes look of a horror film by director David Sandberg is really worth your time! Warning: it's super gory, like, exploding people, smashed skulls... definitely not my type of movie but it's very interesting to hear about all those editing tricks they did. Even cutting from a set to a miniature version of the set during a whip pan! Moreover, the director shows some tiny fixes that blow up the VFX shot count nowadays.

Resonant microtaper leaky-mode computational spectropolarimetry with tens of femtometers spectral resolution and full stokes measurement
Emerging computational measurement techniques for acquiring multi-dimensional optical field information, such as spectrum and polarization, are rapidly advancing and offer promising solutions for realizing high-performance miniature systems. The performance of these computational measurement approaches is critically influenced by the choice of random media, yet a general framework for evaluating different implementations remains absent. Here, we propose a universal analytical model for computat…

A Miniature High-Resolution Tension Sensor Based on a Photo-Reflector for Robotic Hands and Grippers
This paper presents a miniature tension sensor using a photo-reflector, designed for compact tendon-driven grippers and robotic hands. The proposed sensor has a small form factor of 13~mm x 7~mm x 6.5~mm and is capable of measuring tensile forces up to 200~N. A symmetric elastomer structure incorporating fillets and flexure hinges is designed based on Timoshenko beam theory and verified via FEM analysis, enabling improved sensitivity and mechanical durability while minimizing torsional deformat…

Design of meta-surface lens integrated with pupil filter
Metasurface lenses are miniature flat lenses that can precisely control the phase, amplitude, and polarization of incident light by modulating the parameters of each unit on the substrate. Compared with conventional optical lenses, they have the advantages of small size, light weight, and high integration, and are the core components of photonic chips. Currently, the hot topics for metasurface lens are broadband and achromatic devices, and there is still less attention paid to the resolution im…
