Thread: How China bought Germany's robotics crown jewel Quick story: I recently called Kuka German in a thread and got called out - "Kuka is Chinese now." This sent me down a rabbit hole. What I found was straight out of Succession, and it reshaped how the West thinks about tech sovereignty. This is the story of how a Chinese appliance company bought Kuka & kick-started China's robot dominance. ⬇️

Traditional factory automation follows three rules: 1. Minimise degrees of freedom 2. Minimise actuation 3. Minimise the requirement for feedback Let geometry and gravity do the hard work. This is a step feeder. Reciprocating plates push parts upward, one step at a time. Parts that sit stable on the ledge rise to the top. Parts that don't? They tip off and fall back into the hopper. A chain conveyor carries the parts along and a simple tool knocks off any that are misaligned. No robot. No vision. No gripper. Just continuous circulation until every part finds its perfect orientation. Bowl feeders, gravity slides, step feeders, escapements—all built on the same principle. Constrain movement. Let shape and weight do the sorting. Modern robotics throws sensors, actuators, and computing at every problem. Sometimes the smarter move is less.

The vibratory bowl feeder. Patented in 1950. Here is the physics behind this ubiquitous tool. It solves a universal factory problem: you have a bin of randomly oriented parts and need them single-file, perfectly aligned, feeding into the next machine. No vision. No sensors. No code. Just physics. The bowl vibrates with an asymmetric waveform - part vertical, part rotational. During the slow phase, static friction grips the part. During the fast phase, the part slips or micro-jumps. Net result: parts climb the spiral. At the top, geometry takes over. Slots, ledges, and narrowing tracks are machined for one specific part shape. Wrong orientation? Fall back in. Correct? Exit single-file. Every bowl is custom tooled. Change the part, change the bowl. Inflexible? Completely. But at high volume, nothing beats it on cost, speed, or reliability. Running 24/7 since 1950.

Humanoids = stacked actuators. Pure and simple. If you don't understand actuators, you don't understand robots. Actuators are not solved: too heavy, too hot, too inefficient. This is a mega thread on actuator design for humanoid robots, directly from the mind of Humanoid Scott Bookmark it for later 👇

First rule of automation - make your system as simple as possible but no simpler. The tending 'robot' of this wire bender is made up of one linear and one rotary actuator. Not pretty, not flashy, but if it gets the job done 99.999999% of the time with minimal maintenance required - Job is a good un.

5-axis CNC machining – but different... Most 5-axis machines use serial kinematics: stack a rotary A-axis on top of a rotary B-axis, mount that on linear X/Y/Z stages. Each axis carries the weight of everything after it. Heavy and slow. 🤖 The Sprint Z3 uses parallel kinematics: three linear drives working together to create BOTH the Z-axis motion AND the A/B tilt simultaneously. No stacked rotary joints. No heavy tilting head carrying a motor on top of another motor. The entire barrel-shaped headstock moves as one unit vertically in the column, while the three internal drives handle the spindle positioning and orientation. ⚙️ How it works: Three linear actuators are arranged in a circle, all connected to the spindle platform through pivot arms. - Extend all three equally → spindle moves straight up/down (Z-axis) - Extend them different amounts → spindle tilts (A/B axes) It's using geometry instead of stacked rotary joints to create tilt 🤔 Why this is useful: Way less moving mass than serial kinematics. Less mass = faster accelerations, higher precision, better surface finish. For high-speed machining, dynamics matter more than workspace. Question: Is this a good design or overcomplicated❓

Something very satisfying about the way this system opens bags of bulk plastic powder. Not sure if it's the slice or the wiggle

Robots Making Robots in China 🤖 Kuka's Shunde factory produces one industrial robot every 30 minutes, with plans to reduce this to one minute per unit. The facility outputs 30,000 robots annually for industries from automotive to medical applications. The German company's localization strategy has paid off: sourcing 80-90% of components from southern China (versus previously from eastern China) cut production costs by one-third and delivery times from 2-3 months to 2-3 weeks. Recent growth has been driven by Chinese EV manufacturers expanding overseas and electronics companies upgrading production lines. China now represents 25% of Kuka's $4.1B annual revenue.

No robots. No vision. No AI. Just a vibratory bowl feeder, a 2-axis pick-and-place, a turntable, and a gravity slide. This is the automation that actually runs the world. Bowl feeders have been orienting parts since the 1950s. Vibration and geometry—nothing else. Parts walk up a spiral track and fall into line. Pneumatic cylinders move on two axes—up/down and rotate. Hard stops set the positions. No encoders. No feedback loops. Just air pressure hitting a mechanical limit. Air jets blow parts down the slides. Gravity gets a helping hand from a tiny pulse of air to keep the flow consistent. Inflexible? Absolutely. One product, one machine. But for high-volume production, nothing beats it on cost, speed, or reliability. The unsexy backbone of manufacturing.

This is why robots haven't replaced humans in brake line fabrication: - Every vehicle model has unique routing through cluttered underbodies; a skilled worker reads the geometry and adjusts in real time - Per-SKU volumes are low, so setup/programming costs never pay back - The manual jig is low cost; the human brings the compute, sensing, and adaptability for free When variance is high and tooling is cheap, people are still the best option. What would it take to automate this?

Cams ARE the original "programmable" automation - these mechanical marvels orchestrate complex sequences without a single line of code. By carefully profiling cam shapes, engineers encode timing, positioning, and sequencing directly into metal. What makes cams brilliant for automation: - Deterministic timing - no software, no edge cases - Self-synchronising - no syncing clocks of different systems - Incredibly durable - cam-driven machines run for decades - Simple maintenance - mechanics can "read" the program by looking at cam profiles The cam followers, springs, and linkages in machines like this execute intricate routines - bending, cutting, feeding, and positioning with clockwork precision. Each bump and valley on those rotating cams tells a different part of the machine exactly when to move. With all the dancing robots, we sometimes forget how high-tech old-school automation is.

Just discovered Dekal via Timothée Peter's video modeling a spherical five-bar linkage in code. What makes it interesting: > Code-based kinematic design with a differentiable simulation engine > Describe mechanisms in code, instantly get workspace mapping, reachability analysis, and static load testing across every joint > Idea to kinematic validation ASAP; then push to CAD Its a cool project built by a mechanical engineer frustrated with iteration speed in existing tools.

The actuator dilemma that's plagued industrial robotics for 50 years: Electric motors are most efficient at high speeds (5,000-20,000 RPM). But robot joints need slow, controlled movement (~60 RPM max). This forces massive gear reductions (50:1 to 320:1) - and that's where everything breaks down.

Cartwheel Robotics is one of my favourite humanoids... they're building for homes, not warehouses – focusing on intangible 'companionship' rather than quantifiable 'work.' 🤖 This lowers the bar: It's not measured by productivity or ROI. No brutal cost-per-task calculations. No frustration when it fails at a job. Success is simply: do people like it? Does it make them feel something? 🎨 The design choice: Deliberately cartoon-styled to avoid the uncanny valley. Friendly and approachable, not creepy. Warmth and personality over capability. 💣 The challenge: Making something people genuinely connect with is can be harder than optimising for tasks – there's no playbook, no clear definition of done. But founder Scott LaValley (ex-Boston Dynamics, Disney – led Baby Groot, worked on Atlas) has exactly the right background. He knows how to make robots that resonate. 🎯 If they get this right, there could be a bigger moat than approaches that focus on doing 'work'... This is Disney's strategy. What do you think, is this the right humanoid strategy for our current tech?
