20 years of special-purpose machinery and robotics

For 20 years I have worked in industry, mainly for special-purpose machine builders in French-speaking Switzerland, as an engineer, project manager and then head of a 20-strong engineering department. I have designed, led or integrated equipment for a wide range of sectors: watchmaking, medtech, food, automotive, rail and heavy industry.

The projects below are ones I handled personally. I also took part in design reviews of my colleagues’ projects, which broadened my technical knowledge further.

They are presented anonymously, out of respect for the confidentiality of my former employers and their customers. My role is described for each one.

Vision sorting and boxing of colouring pencils

Automatic boxing equipment for colouring pencils. The pencils arrive from hoppers, one per colour, and are placed on a dedicated conveyor. The vision system checks the colour and detects each pencil’s orientation; the pencil is then rotated so that the logo faces upwards before boxing. Linear axes adjust automatically to the different box formats.

  • Hopper feeding, dedicated conveyor, vision-based colour and orientation inspection, pencil rotation, linear axes for format changeover
  • Quotation, project management and mechanical design

Brewing mechanism for a capsule tea machine

For a capsule tea machine, the capsule had to be brewed horizontally, whereas the user inserts it vertically, as with coffee. I designed a mechanism that, with a single lever movement, tilts the capsule to horizontal and closes the brewing chamber. This was my engineering degree project, carried out at a company specialising in capsule systems.

  • Single-lever mechanism, capsule tilting, brewing chamber
  • Mechanical design (degree project)

Palletising with humanoid robots

Integration of 15-axis dual-arm humanoid robots for palletising food products. Products arrive on a conveyor, are identified by vision, then picked by a vacuum gripper with automatic tool changing. A first experience with this type of robot: four of them are now in production at a major Swiss distribution centre.

  • 15-axis NEXTAGE humanoid robots (Kawada, distributed in Switzerland by Rollomatic), vision, vacuum grippers, automatic tool changer, conveyors
  • Quotation, project management and mechanical design

Pallet inspection with deep-learning vision

One of the first industrial integrations of ViDi deep-learning vision, used to analyse pallets carrying a wide variety of food products. Compared with the previous vision system, deep learning made adding new products much simpler: the system just had to be trained on images, with no need to redevelop an algorithm.

  • ViDi deep-learning vision (now Cognex), mixed-product pallet analysis, industrial integration
  • Project management

Trolley sorting with an automated guided vehicle

Pilot line integrating an automated guided vehicle (AGV) to sort trolleys of around 500 kg in a food products hall. The project included purchasing and commissioning the AGV, in collaboration with its Dutch manufacturer, and developing a system that separates the trolleys and presents them to the AGV.

The challenge: trolleys with very varied contents, sometimes empty, and therefore very different weights and centres of gravity from one trolley to the next.

  • Low-profile Lowpad AGV, autonomous navigation, trolley separation system, handling of heavy and variable loads
  • Quotation, project management and mechanical design

Laboratory machine for beverage capsules

Laboratory machine for testing processes before they move into production. It is built around an 8 m oval XTS transport system, to which interchangeable process modules are connected. The first module sealed the capsules, and the machine was designed to take further steps later, such as filling or extraction.

Study for robotic brick wall construction

Integration study for a 6-axis robot to build brick walls on site. Machine safety was the trickiest aspect: an industrial robot on an open construction site, surrounded by workers, cannot be safeguarded as it would be in an enclosed cell. At the end of the study, I identified an existing solution, an autonomous bricklaying robot such as the Hadrian X, which suited the need better than a custom development.

  • 6-axis robot, machine safety on construction sites, feasibility analysis, technology watch
  • Quotation, project management and feasibility study

Study for straightening railway sleepers

Study of equipment to straighten worn and deformed railway sleepers, giving them a second life. Heavy parts and high forces: a design focused on robustness.

  • Tank with agitator, pressure and flow measurement, compact mobile equipment
  • Quotation, project management and mechanical design

Automated assembly of blind slat curtains

Large machine that assembles the slat curtains of external venetian blinds. Coming off the roll former, the slats are fed by conveyor and positioned by a linear-axis pick-and-place unit and a lift. A SCARA robot inserts the hooks between the slats, which are then assembled and placed in the blind’s head box.

The challenge: a particularly delicate hook insertion module, and a machine with many mechanical movements to synchronise.

  • Conveyors, linear-axis pick-and-place, lift, SCARA robot, hook insertion, many synchronised mechanical movements
  • Quotation, project management and mechanical design

Sheet-metal modules for ticket machines

For ticket vending machines, I was tasked with finding a way for the ticket, normally dispensed vertically, to come out lying on its side. One of my first experiences in mechanical design, on sheet-metal sub-assemblies.

  • Ticket guiding and tilting mechanism, sheet metal
  • Mechanical design

Running an engineering department

Since 2024, I have been heading a department of 20 engineers (robotics, electrical engineering, automation and software) at a special-purpose machine builder for heavy industry.

As a former mechanical designer and project manager, I speak everyone’s language and act as the link between the project managers, the design office and my teams.

Hands-on management

Regular one-to-one meetings, a monthly team meeting, weekly follow-ups by discipline and a frequent presence on the shop floor. In-house training develops versatility and knowledge sharing.

Shared methods

Systematic peer reviews, structured working methods beyond the department, and a framework linking each person’s activities to project milestones. Collaboration with other departments has improved markedly as a result.

Management tools adopted by other divisions

An automated multi-department, multi-project resource planning tool, now used by other divisions, complemented by task and hours-budget tracking.

Standards across all four disciplines

Standards and good practice so that every project benefits from the experience of the last. On the software side, a proven common code base now serves as the starting point.
