A wrist-design discussion where motion, cost, and custom gears keep pulling against each other.
The episode keeps its attention on a very stiff wrist design that still manages a full 180 degree range of motion and is built to keep the hand useful.
Robotics, explained through the hardware.
Soft Robotics Podcast follows long-form technical conversations about how robots actually get built. Guests work through wrists, hands, actuators, CAD, humanoids, scanning rigs, and the gap between impressive demos and reliable machines.

Soft Robotics Podcast is built around slow, concrete conversations with robotics guests. It is interested in the machinery behind the promise. The show spends less time selling a future and more time asking why a wrist is stiff, why a thumb is hard to package, why a reducer wears out, or why a camera rig fails when the image is not stable enough. That gives the episodes a grounded texture. A discussion of humanoid hands can turn into a comparison between complex fingers and rugged hook grippers. A conversation about AI robotics can begin with tying a shoelace and end in questions about neuromorphic computing, memory, learning, and coordination. CAD is treated as both history and unsolved frontier, from AutoCAD and wireframe screens to the difficulty of making machine learning understand 3D mechanical design. Manufacturing shows up again and again. Planetary roller screws, harmonic drives, cycloidal reducers, heat treatment, machining order, tolerances, and production speed are not side details; they are where the argument lives. The show also follows applied robotics outside the lab, including robotic arms for footwear scanning, digital twins, virtual try-on, humanoid safety, back-drivable joints, tactile skin, and full-body packaging decisions. Its best moments come when an abstract claim is forced back into a physical object. What does it cost? How long does it last? Can it be made quickly enough? Does the robot need to look like a person, or simply do the work? The pacing is measured and guest-led, with room for long explanations and clarifying follow-ups. It is not polished futurism. It is robotics as a chain of choices, constraints, prototypes, failures, and small breakthroughs.
Made for: For robotics engineers, students, makers, and technically curious listeners who want detailed conversations about real machines. It especially suits people interested in humanoids, actuation, CAD, AI robotics, and manufacturable design.
What sets it apart: The show stands apart by staying close to mechanisms, tradeoffs, and production realities. It treats cost, stiffness, precision, reliability, and packaging as central questions rather than background details.
Hey! I am Marwa ElDiwiny, the host and creator of the Soft Robotics podcast. I started this podcast for a reason, one of them was to ask the questions I always wanted to ask when I was in the lab and reignite my curiosity by talking to interesting people. I found my purpose in this podcast, I hope it may inspire someone somehow along this journey!

It makes robotic design legible by tracing ambitious ideas back to the mechanical compromises that decide whether they work.
Soft Robotics Podcast follows designed objects down to the joints, gears, cameras and compromises that make them work. Marwa ElDiwiny keeps conversations grounded in physical evidence: a robotic wrist becomes a problem of stiffness and range, while AI-assisted CAD is tested…
A shoelace becomes a robotics benchmark, and suddenly your own fingers look suspiciously overqualified.
