Fault Diagnosis on Induction Motor using Machine Learning and Signal Processing
The detection and identification of induction motor faults using machine learning and signal processing is a valuable approach to avoiding plant disturbances and shutdowns in the context of Industry 4.0. In this work, we present a study on the detection and identification of induction motor faults using machine learning and signal processing with MATLAB Simulink. We developed a model of a three-phase induction motor in MATLAB Simulink to generate healthy and faulty motor data. The data collecte…

The Register: Palantir CEO says software saves Europe from 'goose step'

Me going from a full stop to moving at a low gear is insanely smooth now, I don't stall at all, and haven't in at least a week.
I can get right on a highway in some fairly quick time, and with smooth shifting in the process.
My downshifting is immaculate, and I can estimate engine RPMs for the current road speed fairly well.
And I also learned some cool tricks depending on the situation I can use - like popping the clutch to start the car, which I used not even two days ago after work when the car wouldn't start with the key (turned out to be a loose battery terminal, so starter motor couldn't turn)

A New Method for Sensorless Estimation of the Speed and Position in Brushed DC Motors Using Support Vector Machines
Currently, for many applications, it is necessary to know the speed and position of motors. This can be achieved using mechanical sensors coupled to the motor shaft or using sensorless techniques. The sensorless techniques in brushed dc motors can be classified into two types: 1) techniques based on the dynamic brushed dc motor model and 2) techniques based on the ripple component of the current. This paper presents a new method, based on the ripple component, for speed and position estimation …

Factors influencing the stability of the motor-clutch model on compliant substrates under external load
Cellular migration is crucial for biological processes including embryonic development, immune response, and wound healing. The myosin-clutch model is a framework that describes how cells control migration through the interactions between myosin, the clutch mechanism, and the substrate. This model is related to how cells regulate adhesion, generate traction forces, and move on compliant substrates. In this study, we present a five-dimensional nonlinear autonomous system to investigate the influ…

Hyperphosphorylation-Induced Phase Transition in Vesicle Delivery Dynamics of Motor Proteins in Neuronal Cells
Synaptic vesicle transport by motor proteins along microtubules is a crucial active process underlying neuronal communication. It is known that microtubules are destabilized by tau-hyperphosphorylation, which causes tau proteins to detach from microtubules and form neurofibril tangles. However, how tau-phosphorylation affects transport dynamics of motor proteins on the microtubule remains unknown. Here, we discover that long-distance unidirectional motion of vesicle-motor protein multiplexes (V…

Bypass mechanism of F$_1$-ATPase for asymmetric enzyme kinetics
We discovered novel enzyme kinetics of F$_1$-ATPase, a biomolecular motor that synthesizes and hydrolyzes adenosine triphosphate (ATP), using single-molecule experiments and numerical simulations. The enzyme kinetics of F$_1$-ATPase followed the Michaelis-Menten equation in ATP hydrolysis but deviated from it in ATP synthesis, indicating asymmetric enzyme kinetics between ATP synthesis and hydrolysis. Numerical analysis based on a theoretical model revealed a bypass mechanism underlying asymmet…

Can Transformers Predict Vibrations?
Highly accurate time-series vibration prediction is an important research issue for electric vehicles (EVs). EVs often experience vibrations when driving on rough terrains, known as torsional resonance. This resonance, caused by the interaction between motor and tire vibrations, puts excessive loads on the vehicle's drive shaft. However, current damping technologies only detect resonance after the vibration amplitude of the drive shaft torque reaches a certain threshold, leading to significant …

With current propellant/motor Isp and assuming a full from-scratch design (i.e. not optimizing for low cost using existing engines and avionics), what's the lower bound on how small an orbital launch vehicle could be if payload capacity is not a concern?
In other words, suppose some company/country/rich person wanted to put a very particular grain of sand into low earth orbit without using an existing vehicle and didn't care about the program scaling to bigger payloads, how big…

Safe & Accurate at Speed with Tendons: A Robot Arm for Exploring Dynamic Motion
Operating robots precisely and at high speeds has been a long-standing goal of robotics research.Balancing these competing demands is key to enabling the seamless collaboration of robots and humans and increasing task performance. However, traditional motor-driven systems often fall short in this balancing act.Due to their rigid and often heavy design exacerbated by positioning the motors into the joints, faster motions of such robots transfer high forces at impact. To enable precise and safe d…

Recent progress in the physical principles of dynamic ground self-righting
Animals and robots must be able to self-right on the ground after flipping over to survive or operate. Biology research has described various strategies and measured motor control patterns in many species. Robotics research has designed many mechanisms to enable ground self-righting. However, the physical principles governing ground self-righting transitions are relatively less known, except limited understanding in turtles with rigid shell in two dimensions. Here I review recent progress which…

Using Capability Maps Tailored to Arm Range of Motion in VR Exergames for Rehabilitation
Many neurological conditions, e.g., a stroke, can cause patients to experience upper limb (UL) motor impairments that hinder their daily activities. For such patients, while rehabilitation therapy is key for regaining autonomy and restoring mobility, its long-term nature entails ongoing time commitment and it is often not sufficiently engaging. Virtual reality (VR) can transform rehabilitation therapy into engaging game-like tasks that can be tailored to patient-specific activities, set goals, …

An Efficient Model-Based Approach on Learning Agile Motor Skills without Reinforcement
Learning-based methods have improved locomotion skills of quadruped robots through deep reinforcement learning. However, the sim-to-real gap and low sample efficiency still limit the skill transfer. To address this issue, we propose an efficient model-based learning framework that combines a world model with a policy network. We train a differentiable world model to predict future states and use it to directly supervise a Variational Autoencoder (VAE)-based policy network to imitate real animal…

The weak relationship between ankle proprioception and gait speed after stroke a robotic assessment study
Ankle proprioceptive deficits are common after stroke and occur independently of ankle motor impairments. Despite this independence, some studies have found that ankle proprioceptive deficits predict gait function, consistent with the concept that somatosensory input plays a key role in gait control. Other studies, however, have not found a relationship, possibly because of variability in proprioception assessments. Robotic assessments of proprioception offer improved consistency and sensitivit…

Aligning Learning with Communication in Shared Autonomy
Assistive robot arms can help humans by partially automating their desired tasks. Consider an adult with motor impairments controlling an assistive robot arm to eat dinner. The robot can reduce the number of human inputs -- and how precise those inputs need to be -- by recognizing what the human wants (e.g., a fork) and assisting for that task (e.g., moving towards the fork). Prior research has largely focused on learning the human's task and providing meaningful assistance. But as the robot le…

Under-actuated robot grippers as a pervasive tool of robots have become a considerable research focus. Despite their simplicity of mechanical design and control strategy, they suffer from poor versatility and weak adaptability, making widespread applications limited. To better relieve relevant research gaps, we present a novel 3-finger linkage-based gripper that realizes retractable and reconfigurable multi-mode grasps driven by a single motor. Firstly, inspired by the changes that occurred in …
