THE ROBOT TAKES THE SHOCK ⚡ What if robots could take on dangerous work while skilled humans stay in control? Scott Walter, and I sat down with Theo Nash, CEO of Mundane, to explore how they're using robotics to tackle hazardous work. With haptic feedback, skilled workers can remotely control the robots and feel what they're doing, while the robot takes on the physical exposure. We talk about the technology, the challenges of building the company, what Mundane would do differently, and why they believe robotics should augment skilled workers, not replace them.

Zmotor Linear Actuator Teardown: Inside the Stator, Rotor & IPRS What’s actually inside a linear actuator built for humanoid robots? In this teardown, we will take one apart piece by piece and explains how each part works. It’s all packed into a body just 32 mm in diameter. You’ll see: Stator: the fixed copper windings that create the magnetic field Rotor: spins inside the stator and drives the screw IPRS (Inverted Planetary Roller Screw): turns rotation into strong, precise linear motion Actuators like this decide how strong, fast and precise a humanoid can move.

Digit 5: What Are They Not Showing Us? Agility’s latest Digit demo shows a pretty significant change in the robot’s design. But it also raises a few questions. One of the biggest ones is speed. Speed was never mentioned in their specs. And then there’s that unusually large backpack. Battery? Compute? Cooling? Something else? Digit is also one of the heavier humanoids out there, so it’s worth asking what that means for safety. Scott Walter and I sat down to go through the new design and the footage. One thing we noticed: Digit doesn’t actually take a step in the footage we reviewed. There’s also footage that appears to be CGI rather than an actual physical demonstration. None of this necessarily means the technology doesn’t work. It just means there are still things we can’t really judge from the demo. And Agility is, of course, welcome to respond or correct anything we got wrong.
