    Why Robot Arms Still Cant Tie a Knot
    Jun 15 2026
    Episode 52 of The Robotics Podcast tackles one of the most deceptively difficult tasks for robots: tying a knot. Lucas and Luna explore why a simple overhand knot — something a child can master — confounds even advanced robot arms. They discuss the physics of string, the problem of continuous contact, and how researchers at MIT and UC Berkeley are using reinforcement learning and tactile sensors to crack this challenge. They also touch on the broader implications for surgical suturing and fishing line automation. A must-listen for anyone fascinated by the gap between human dexterity and robotic manipulation. #Robotics #RobotArms #KnotTying #Dexterity #Manipulation #TactileSensors #ReinforcementLearning #MIT #UCBerkeley #SurgicalRobots #Automation #FishingIndustry #Technology #RoboticsPodcast #FexingoBusiness #BusinessPodcast #ScienceAndTech #Hardware Keep every episode free: buymeacoffee.com/fexingo

  • Why Robot Arms Still Can't Open a Door

    Why Robot Arms Still Can't Open a Door
    Jun 14 2026
    Lucas and Luna explore why robot arms still struggle with one of the most basic human tasks: opening a door. They break down the physics of door handles—levers vs. knobs—and the kinematic challenges of coordinating arm and wrist motion while applying the right force. Lucas cites a 2025 study from MIT CSAIL showing that even the latest robot arms fail on standard hinged doors about 40% of the time. They discuss why simulation-to-reality transfer is especially hard for door-opening, and how new torque-sensing joints and tactile feedback loops are slowly closing the gap. A practical, surprising look at why your office door is still a frontier for robotics. #RobotArms #DoorOpening #Robotics #MITCSAIL #Kinematics #TorqueSensing #TactileFeedback #SimToReal #Hardware #AutonomousSystems #IndustrialRobots #Technology #FexingoBusiness #BusinessPodcast #Podcast #FutureOfWork #AI #DeXterity Keep every episode free: buymeacoffee.com/fexingo

  • Why Robot Hands Still Cant Handle a Live Wire

    Why Robot Hands Still Cant Handle a Live Wire
    Jun 14 2026
    Episode 50 of The Robotics Podcast tackles why robot hands still can't handle a live wire. Lucas and Luna dive into the specific challenges of robotic manipulation with flexible, energized cables — a problem that plagues everything from factory wiring to home-assistance bots. They break down the physics: why compliant grippers fail with limp wires, why force sensing goes haywire with current, and how a team at MIT's CSAIL recently got a robot to plug in a charging cable with 80% success. Along the way, they compare to prior episodes on wet objects and slippery soap, and explore what this means for the next generation of household robots. If you've ever wondered why your robot vacuum can't untangle its own cord, this episode explains the hard limits of current hardware. #Robotics #RobotHands #Manipulation #CableHandling #LiveWire #MITCSAIL #ForceSensing #CompliantGrippers #IndustrialRobots #AutonomousSystems #DeformableObjects #SoftRobotics #TactileSensing #RobotVacuum #FexingoBusiness #BusinessPodcast #Technology #WeeklyTech Keep every episode free: buymeacoffee.com/fexingo

  • Why Robot Hands Fumble a Slippery Bar of Soap

    Why Robot Hands Fumble a Slippery Bar of Soap
    Jun 13 2026
    Episode 49 of The Robotics Podcast tackles a deceptively hard problem: gripping a slippery, wet bar of soap. Lucas explains why traditional robotic grippers fail on objects with low-friction, non-rigid surfaces, and why even state-of-the-art tactile sensors struggle. Luna points out that this isn't just a bathroom curiosity—it's a barometer for progress in manufacturing and food handling. They discuss the physics of friction in wet environments, the role of suction-based grippers, and why researchers at places like MIT's CSAIL and Carnegie Mellon are using soap as a benchmark. By the end, you'll understand why your dishwasher's robotic future is still a few breakthroughs away. #RoboticGripping #TactileSensors #SlipperyObjects #FrictionPhysics #IndustrialRobots #MITCSAIL #CarnegieMellon #ManipulationChallenges #SoftRobotics #SuctionGrippers #ManufacturingTech #FoodHandlingRobots #AutomationLimits #RoboticsResearch #FexingoBusiness #BusinessPodcast #Technology #RoboticsPodcast Keep every episode free: buymeacoffee.com/fexingo

  • Why Robot Arms Still Can't Slice a Tomato

    Why Robot Arms Still Can't Slice a Tomato
    Jun 13 2026
    In this episode, Lucas and Luna explore the surprisingly difficult challenge of teaching a robot arm to slice a tomato. They break down the physics of cutting with a knife — variable friction, deformable objects, precise force control — and explain why even the most advanced industrial arms from companies like Fanuc and ABB struggle with a task a sous-chef does in seconds. With comparisons to Amazon's robotic depalletizing and a recent paper from MIT's CSAIL, they show why food handling is robotics' next great frontier. #RobotArms #TomatoSlicing #DeformableObjects #ForceControl #Robotics #FoodHandling #Fanuc #ABB #MITCSAIL #AmazonRobotics #AutonomousSystems #IndustrialRobots #Hardware #Technology #FexingoBusiness #BusinessPodcast #LucasAndLuna #TheRoboticsPodcast Keep every episode free: buymeacoffee.com/fexingo

  • Why Robot Arms Still Cant Handle a Raw Egg

    Why Robot Arms Still Cant Handle a Raw Egg
    Jun 12 2026
    If you've ever tried to get a robot to pick up a raw egg without smashing it, you know the problem: the gripper either crushes the shell or can't hold on. In this episode, Lucas and Luna dive into the physics of why robot arms struggle with fragile, deformable objects. Lucas explains the fundamental trade-off between grip strength and delicacy, using the example of a surgical Robot that can sew tissue but can't hold an egg. Luna brings in data from a 2025 IEEE study showing that even with pressure sensors, robots fail to handle eggs 40% of the time. They discuss the challenge of real-time force feedback and why the human hand's ability to adjust grip intuitively is still beyond robots. The conversation touches on a robotics startup that tried to solve this with soft robotics and a novel gripper design, but hit a wall with material fatigue. Lucas leaves listeners with a thought: until robots can adapt grip mid-task like a human, a simple omelette remains a moonshot. #Robotics #RobotArms #RobotGrippers #EggHandling #FragileObjects #SoftRobotics #ForceFeedback #IEEE #RoboticsStartup #GripperDesign #DeformableObjects #Manufacturing #Technology #FexingoBusiness #BusinessPodcast #TheRoboticsPodcast #AutonomousSystems #IndustrialRobots Keep every episode free: buymeacoffee.com/fexingo

    Why Robot Hands Can't Handle a Raw Egg
    Jun 12 2026
    In this episode of The Robotics Podcast, Lucas and Luna explore a deceptively simple challenge that keeps robotics researchers up at night: picking up a raw egg without breaking it. They break down the physics of fragile objects, the trade-off between speed and precision, and why 'egg handling' is a benchmark for next-generation grippers. Lucas cites a 2025 study from MIT's Soft Robotics Lab showing that a state-of-the-art tactile sensor array still fails 30 percent of the time with supermarket eggs. Luna questions whether the industry should pivot to biomimetic materials rather than more sensors. Specific, surprising, and grounded in real lab results — this is robotics at the edge of what's possible. #Robotics #SoftRobotics #RobotHands #EggHandling #GripperTechnology #TactileSensors #MIT #FragileObjects #Manipulation #IndustrialRobots #AutonomousSystems #Biomimetic #DeformableObjects #Prehension #TechPodcast #FexingoBusiness #BusinessPodcast #Technology Keep every episode free: buymeacoffee.com/fexingo

    Jun 11 2026
    Episode 45 of The Robotics Podcast dives into a deceptively simple problem: why robots can't open a resealable plastic bag. Lucas and Luna explore the physics of thin-film manipulation, the failure of vacuum grippers on flexible materials, and recent research from MIT's CSAIL using electrostatic adhesion and sensory feedback. They discuss why this specific task stumps even advanced systems like the Shadow Hand and what it reveals about the gap between human dexterity and robotic manipulation. The episode also touches on how solving this could unlock automation in food processing, medical packaging, and logistics.
