💥Introducing FACTR 2, learning external force sensing on commodity robot arms without needing dedicated sensors. We show that learned force signals enable force-feedback teleop on low-cost arms and improve BC policies. FACTR 2 consists of: 1. Neural External Torque (NEXT): learns external forces without needing dedicated force sensors. 2.... show more

Low-cost teleop systems have democratized robot data collection, but they lack any force feedback, making it challenging to teleoperate contact-rich tasks. Many robot arms provide force information — a critical yet underutilized modality in robot learning. We introduce: 1. 🦾A low-cost, force-feedback-enabled teleop system. 2. 🥊Force-Attending Curriculum Training (FACTR) uses force to improve generalization in complex, contact-rich tasks. 🧵(1/N)

Excited to share that our work NeuralActuator: Neural Actuation Modeling for Robot Dynamics and External Force Perception has been accepted to #RSS2026! Your robot — even a low-cost one — can feel external forces without torque or tactile sensors. TL;DR: NeuralActuator is a neural actuator model that jointly predicts 1️⃣torque to capture the nonlinear and time-varying current–to–torque relationship of low-cost servos, 2️⃣external contact forces (and force detection gates) for sensorless force perception, 3️⃣and motor conditions that indicate each motor’s operating regime. Here is a fast-forward video clip ⬇️ We are also covering more robots like LeRobot-S101 and Franka Panda. More details coming soon.

What if some parts of a robot demonstration are more important than others? Most of a trajectory is free-space motion. But success or failure is often determined by a few critical moments around contact. In FACTR 2, we use force to find these moments and prioritize them for training. We find this helps policies learn better alignment and recovery behaviors, like the example below. w/ Steven Oh Jason Liu 🧵(1/N)

Taiwan has placed its forces on alert following a show of force from China around its shores. Beijing said the military drills are a warning against "external interference".

🚨 Australian Police seem to have reached boiling point, as they ground & pound a ‘Pro Hamas’ protestor! Thoughts on the force being used here… 1. Too much force 2. Just enough force 3. Not enough force

In house tactile sensor prototype. Detects taps, motion, and multiple contact with force magnitudes. Built to be cheap, robust, and replaceable. Not in our demos yet, still WIP. We pair simple tactile sensing with torque transparent joints to recover rich contact without expensive sensors.

Open-source dexterous hands with fingertip sensors! 🪬 ORCA Dexterity just released three dexterous hand models. Their mission: is to democratize robotic hand dexterity. They're sharing progress on exceptional, low-cost hardware and a software layer from low-level control to robotic hand learning. This is the open-source approach to dexterous manipulation. It has 83 taxels per finger with 0.1 N force detection which pretty is impressive for an open-source design. Tactile sensing is critical for dexterous manipulation, knowing contact forces enables gentle grasping, slip detection, and force-controlled assembly. Also 700g weight for the lite version makes it practical for mounting on robot arms without exceeding payload limits. Lower weight means faster movements and lower torque requirements. Open hardware accelerates robotics by letting researchers and builders modify designs for their specific needs without starting from scratch! ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

Upper Body French Contrast Training 1. Strength Movement - high force low velocity 2. High Force Plyometric - low load high intent 3. Fast Strength Movement - ballistic 4. High Speed Plyometric - assisted / overspeed This sequence serves as a comprehensive peaking method by targeting multiple points along the force velocity spectrum within a single complex

WATCH: From April 17 to May 4, the air forces of China and Egypt held the first “Eagles of Civilization-2025” joint training at an Egyptian air force base. The Chinese Air Force dispatched J-10C, KJ-500 and YY-20 aircraft to participate. It was the first time that China sent force packages to Africa for joint training, said Chinese Defense Ministry spokesperson Zhang Xiaogang. (Video: Chinese Defense Ministry)
