To link a moving part to a linear drive, the reflex is a rigid connection, firm, with no play.
Paradoxically, if the moving part can warp, or the hain pulls slightly off axis, a rigid connection forces the part and ends up increasing the play it was meant to prevent. Rigidity, in this case, is the problem.

The solution for this case was an oscillating coupling - a link that allows for controlled movement in the directions where the misalignment appears, and firm where it has to be.

The principle is a trailer hitch: the ball gives angular freedom without releasing the connection. The part can move closer, further, or warp slightly without forcing anything and without gaining play.

Is your company really missing just one more robot? Time to see the bigger picture.
Automation used to belong to large manufacturers. With AI, cheaper robots and systems become commodities, as more capable mechanisms are brought within reach of small and medium producers - exactly the ones now facing labour shortages and volatile demand, who need stable and predictable production.

The barrier those firms hit, which the industry itself recognises, is clear: it is not only the robot, but the engineering capacity around it. The vision, the process design, the communication, the electrical optimization, and the whole integration responsibility.

An industrial robot is a standard part you can buy, while a machine that solves your specific production problem, is not. Someone has to define what the machine must do, design the mechanics around the robot's reach, integrate the vision, the pneumatics, the safety, and make it all run as one single system.

This is the gap that must come from outside, and exactly the one we work in.

The difference between hiring capacity or booking a result.

Capacity is buying hours: an extra pair of hands to draw, who deliver what was asked and hand it back. Whoever answers for the result is whoever takes on the whole package — requirements, architecture, production-ready documentation — and stays until the machine starts up. When something doesn't fit in fabrication, assembly or startup, there's no 'that wasn't in my scope'. There's someone who answers.

It all shows where projects tend to fail - in the handover from drawing to real machine, and from prototype to production.

That's the position we hold: rest assured someone is taking care of the complete package until the machine works.

A great machine not only has to work, but also be manufactured, transported, lifted, installed and maintained for years.
If the transportation is only thought about at the end, you find out the base won't take the forklift forks, that there are no lifting points, that the machine doesn't fit out the door or onto the truck, often too late.

Reinforcing the base for the forklift, providing clear dedicated lifting points, planning breakdown for transport, and leaving access for maintenance - all of it goes into the design from the first sketch. Designing only the main function delivers a machine that works in the CAD only.

The whole lifestyle much be integrated in the machine Architecture - avoiding late retrofits or late start-ups.

The number one cause of a machine project going off the rails: a badly defined scope.
What each side assumed without saying, what was left undecided, what was implicit and each one read their own way.

The way to avoid it is to separate four layers explicitly, before starting.

Assumptions: everything taken as true that, if false, changes the project - load weight, dimensions of the final product, operating conditions.

Open items: what's still to be decided, clearly listed - to be address later, no excuses.

Scope: what's in, concrete and direct.

Exclusions: what's out, in writing - whatever it is.

Making every assumption explicit protects both sides. The end user knows exactly what they get - engineering to manufacturing? Support to SAT? Change requests? A scope that clearly states what and how it is being done is more solid that one that promises everything.

Structuring scope like this: with the four layers separated, is the first engineering work of a project - before any drawing.

As a vision system throws false positives, the reflex is to go into the algorithm - tune parameters, train on a wider set, complicate the software.

But the cause may not be in the code. In this case, it was in the light.



When the lighting illuminates everything equally, the camera sees the back rows as well as the front one, and does not discern between them. The solution arises from a physical distinction - direct the light only to the nearest row and leave the ones behind in the shadow. This way, the camera sees only what it has to see, and reduces the load on the software.



The best special machine engineers see where the domains meet - mechanics, optics, electric, software - and solves the cheapest one, while it is not often the first to come to mind.



Looking for the solution in the correct domain, and not the most obvious one, is part of integrating a complex machine.

In 2024, the world installed 542,076 industrial robots. Electronics took the top spot with about 129,000 installations - 24% of the total. Automotive, long the face of industrial robots, came second with 126,088 - 23%, and falling (-6,9% on the year).

Third: metal and machinery, with around 87,000 installations, 16% of the world total, and its share grew by 2 percentage points while automotive shrank.

The pattern under those numbers matters more than the ranking. Robotics is spreading out of its traditional home in automotive and into general industry — metalworking, machinery, the shops that build and process metal parts. The global operational stock is now 4.66 million robots, and the fastest-shifting share is moving toward exactly the kind of work special-purpose machines serve.


It is clear the market is adapting to the next-gen automation. Electronics and metalworking keep racing to the top. The key has and will always be having the right knowledge and expertise. Find Auvyar at www.auvyar.com

The industrial robot envelope - what is it and why does it matter?
A robot has a defined working envelope - excluding accessories one can add. It dictates where the base sits, how tall the structure is, how far the gripper goes, and clearance left for parts and the operator, if interaction is needed.

Designing a machine around a robot starts by respecting that envelop, as well as being a robot selection criteria. If the base ends up in the wrong place, the arm doesn't reach a point of the operation, and you find that out late — with the structure already drawn, forcing you to reposition everything. Robot integration is geometry before it's anything else: first you make sure everything the robot has to touch is within reach, and only then do you design the rest.

Still, you need to know what torque passes through it - to size, understand a failure, and choose a component.

Indirect estimation is the approach. For the useful torque, start with the electrical power the motor draws and the line speed - power divided by angular velocity gives the torque.

For a looping friction torque, you start from the clamping force and the friction coefficient. Each path gives a grounded value, from quantities measured or know, without touching the shaft.

Of course it is not as exact or calibrated as a strain gauge, but it is enough to decide with a basis, without relegating to guessing. This is the clear differentiation between engineering and a random shot.

Welded: rigid, cheap in material, but heavy and hard to modify once finalized (can be integrated into machining if needed).

Bolted: modular, demountable for transport, but needs care with tolerances and is one more task for commissioning.

Aluminium profile: light and quick to assemble, more expensive in material, but the extra can be recovered in labout and lead time.


The choice isn't made by habit or whichever is best known, but from the load the structure carries, how much it may need to be changed/modules added, and the weight that matters for transport, as well as the budget. Besides this, there may be different sections of the same machine done in different types of structures.


Deciding the construction type must always come from the right analysis and criteria, as part of the design process - the baseline of Auvyar's engineering.
