As a controls engineer who has implemented and assisted with dozens of robotic manufacturing cells, the problem isn&#x27;t the motion planning or compute, it&#x27;s legacy product support and ease of onboarding new hires.<p>Any given cell may be in production for 10 years - some only for 5, but some for 20 or more - and you need &lt;24 hour response times to any mechanical issues that may arise over that duration. Also, one can&#x27;t expect that the original programmer will be available to diagnose and debug issues that arise in the field after a year or two, so you need a large pool of technicians and maintenance personnel that can understand the software and be productive in the first hour after being introduced to the machine. None of this is valued by academics, instead, the fundamentals of the process of a single lab trying to prove merit as PhD students and, once that credential is acquired, move on to greener pastures is anathema to both of these ideas.<p>The problem is that academia is working in ROS (now ROS 2), writing Python and VHDL, while the real work in the industry is being done in proprietary vendor tooling that&#x27;s backwards compatible with training from the 80s. They&#x27;re proudly advertising touchscreens and full-color 5.7&quot; displays on their teach pendants, as if their customers were still 20 years in the past.<p>Yes, academia, I do want sub-millimeter repeatability, and flawlessly smooth motion planning. I want collision detection that accommodates both the inertia of the arm itself and any end-of-arm tooling, including cable harnesses with distributed loads. I want automatic singularity avoidance and trivial point and frame manipulation. I want 24-bit encoders for resolution, and I want angular velocities to the moon, and to make those work together I need servo loop rates and high-speed skip responses at 1, 2, or 10 kHz. I want 4D stop position prediction to avoid intersection of the robot arm with complex assemblies and safety zones imported from CAD. I want all these things cheaper and faster, with more storage.<p>But I need these to be accessible by Billy Joe, whose only credentials that got him the job in the maintenance department is that he helped out his daddy working with a welder and an old clapped-out Bridgeport on the farm growing up. Billy is probably my best tech on 3rd shift, and he&#x27;s never learned to type on a full-size keyboard, just his smartphone... and on a robot teach pendant.

Did you know it takes almost a hundred ms for a signal to go from your fingers to your brain? Did you know that the brain is constantly predicting the future to make up for its slow reaction time? Did you know even small computers are <i>really really</i> fast? If you did then you&#x27;d probably guess that initiatives like this are a waste of time and money. The difficulty is in the software, not the hardware, or the compute layer. With good algorithms our current crop of robots are already fully capable of producing trillions more in economic value than they do today.<p>We do not need hardware acceleration in robotics. Can we use it if it exists? Sure, but do we care about &quot;democratizing&quot; it? No.<p>There is a place for hardware acceleration in robotics that is making a huge difference and that&#x27;s in simulation. GPUs, the once and future king, make training robust neural networks possible and fast. If you&#x27;re an investor reading this who needs a reminder, bet on software.

While hardware accelerators in robotics are very cool, and needed. The fact that the entire workflow is ROS2 centric is a bummer. FPGA and Accelerator Programming is already a huge PITA, and despite it&#x27;s success ROS is really one of the worst frameworks I&#x27;ve ever used in terms of DX. It makes an already hard problem, needlessly harder.<p>I wouldn&#x27;t be surprised if they developed their own FPGA programming environment based on C++ and CMake, and all kinds of other custom language and tool shenanigans.

Looks impressive to a layman like myself. I&#x27;m guessing it addresses the global shortage of single-board computers like Raspberry Pis right? Curious to know how long it&#x27;ll take to do that as well.

comparison using Jetson TX2 or Xavier could have provided better insight instead of Nano 2G which struggles even in basic task but otherwise looks quite promising
