At electronica 2026 (10-13 November, Munich, Germany), the Chomerics Division of Parker Hannifin, a world leader in motion and control technologies, will present its advanced ventilation panels with electromagnetic shielding. At stand B3.457, Parker Chomerics will demonstrate how its stainless steel honeycomb technology lets electronic enclosures deliver effective electromagnetic shielding while maximising airflow for efficient thermal management.

The high-density data centre challenge

The rapid expansion of data centres and high power density electronic systems makes heat management inside equipment enclosures increasingly complex. On top of that, sensitive electronic devices must be protected from electromagnetic interference (EMI), which can degrade system performance.

Stainless steel honeycomb ventilation panels

Parker Chomerics’ stainless steel honeycomb ventilation panels address both needs: they provide airflow of up to 96% and deliver highly effective electromagnetic shielding.

Other advantages of the stainless steel ventilation panels include noise attenuation, corrosion protection and fire resistance. Parker Chomerics engineering teams work closely with customers to develop tailored solutions based on their specific application requirements. Solutions can be fully customised in terms of size, shape, material, frame, gaskets and plating. Thanks to advanced manufacturing technologies, the company supplies high-quality ventilation panels at a competitive price, combining high production volumes with dimensional precision.

Automated optical inspection allows the work to be monitored in real time and defects to be detected early, while automated laser welding ensures precise, repeatable joints with minimal thermal distortion. This strengthens structural integrity and achieves uniform electromagnetic shielding. Data-driven quality control is applied throughout the production process: statistical process control and traceability ensure consistent, repeatable performance. The process maintains a capability level with Cp and Cpk values above 1.67, commonly recognised as “excellent”.

Parker Chomerics supports customers who need fast development and production: prototypes of the stainless steel ventilation panels are available in one week and production lead times are just two to four weeks.

Statement from Keith McDonald

“Parker Chomerics helps its customers tackle the challenges of electromagnetic protection and thermal management without compromising airflow, quality or production speed,” said Keith McDonald, International Director of Sales at Parker Hannifin. “Our stainless steel honeycomb ventilation panels are a highly engineered, customisable solution that ensures reliable enclosure performance and lets customers move efficiently from prototype to production.”

Thermally conductive materials on show

At electronica 2026, Parker Chomerics will also present two recently introduced thermally conductive materials.

THERM-A-GAP PAD 120LOE

THERM-A-GAP PAD 120LOE will also be on display, a high-performance thermal elastomer offering a thermal conductivity of 12.0 W/m-K, with an exceptionally low level of silicone oil bleed and migration. Designed for high-performance electronic applications, this new material delivers high thermal performance, low compression force, vibration attenuation and physical protection of sensitive components.

THERM-A-GAP® PAD 30RB

The new THERM-A-GAP® PAD 30RB thermally conductive elastomer pad, with a thermal conductivity of 3.0 W/m-K, offers excellent elastic recovery and good reusability, allowing repeated compression and reapplication with minimal loss of thickness. It is used in automotive electronics, telecommunications equipment, data processing and consumer electronics.

WorMa is an amphibious snake robot that moves on land and in water with the same undulating motion. It has no reconfiguration mechanisms: no leg that retracts, no propeller that comes out of the body. It adapts to different terrains by shifting its own weight through water pumped between two internal tanks. The robot is about 50 cm long and its body is made up of five 3D-printed segments connected by four motorised joints.

The underlying idea is simple but far from trivial. Instead of looking for a single compromise that works everywhere, the robot continuously adapts its balance to the terrain it is about to face. Four servos generate the wave that pushes it forward, while an ESP32 supervises the system. Under the body, silicone pads provide directional grip during crawling; on the sides, foam discs provide buoyancy in water.

Two 300-gram latex tanks shift the centre of gravity

The heart of the adaptation lies in two latex balloon tanks, one in the head and one in the tail. Together they hold about 300 grams of water, that is 28% of the robot’s total mass. A 12 V peristaltic pump mounted centrally transfers water between the two tanks and shifts the centre of gravity. A complete transfer takes about 110 seconds.

A peristaltic pump with a DC motor and a silicone tube is the natural choice for this task: the 12 V peristaltic pump works without valves and does not contaminate the water with lubricants. The board that supervises everything is an ESP32, while four servos generate the undulating motion.

The numbers tell the story of how the behaviour changes better than any description. With the weight forward, the robot is the only configuration able to climb a 19.5 degree slope, and it cuts the cost of transport by at least 33% compared with the other distributions. Shifting the water towards the tail, on the other hand, increases swimming speed by up to 26% and improves swimming efficiency by 52%.

How WorMa climbs a 15 cm step and gets back out of the water

The sequence for overcoming a 15 cm step shows the robot’s logic well. First it moves the weight forward for grip, then it transfers it towards the rear to lift the front section. Finally it brings it forward again after hooking onto the upper edge. The same wave that crawls on flat ground also works uphill, in water and when climbing back out of the water onto dry land.

• ESP32 for system supervision
• A 12 V peristaltic pump mounted centrally
• Four servos to generate the undulating motion
• Four motorised joints between the segments
• Five 3D-printed body segments
• Silicone pads for directional grip
• Foam discs for buoyancy
• Two latex balloon tanks holding about 300 grams of water

Anyone who wants to retrace the work will find the story of the project and the experimental tests in the scientific paper published in Advanced Robotics Research. The interesting point for builders is that the adaptation requires neither more legs nor more motors: a different weight distribution is enough. And the numbers prove it, from 33% less cost of transport to 52% more efficiency in water.

The Gearotons M17 is a NEMA-17 servo motor that combines motor, closed-loop driver, motion controller and magnetic encoder in a single body. No external boxes, no protrusions: the face measures 42.2 x 42.2 mm and the shaft is 5 mm, just like a normal stepper. The project is open source under the MIT licence and comes from Tom Rodinger for Gearotons, a brand of Move the Needle Limited. Prices start at 20 dollars, with worldwide shipping from Shenzhen.

The closed-loop control with encoder and PID loop runs at 32 kHz on the STM32G0 microcontroller. So position correction happens far more often than a normal axis needs. The motors are daisy-chained on an RS-485 bus at 230400 baud. In addition, each motor has a unique 64-bit ID and a one-byte alias, so every unit in the chain can be addressed individually.

The four sizes cover different needs, all with the same electronics inside. Here are the declared figures:

• M17-34: 33.5 mm long, holding torque 0.28 N·m, weight 210 g, rated power 24.0 W
• M17-40: 40.1 mm long, holding torque 0.42 N·m, weight 285 g, rated power 26.4 W
• M17-48: 48.7 mm long, holding torque 0.55 N·m, weight 360 g, rated power 26.4 W
• M17-60: 59.7 mm long, holding torque 0.65 N·m, weight 470 g, rated power 26.4 W

All sizes run from 12 to 24 V, draw up to about 1.1 A and reach up to 560 RPM. Protection is IP20, so indoor use. The price ranges from 20 to 35 dollars depending on size, and the USB-RS-485 adapter is offered at 10 dollars.

Python and Arduino libraries with no STEP/DIR timing

The Python and Arduino libraries convert the units chosen by the user into commands for the motor. So you write degrees, rotations, radians or encoder counts, and seconds or milliseconds for time. There is no need to handle STEP/DIR timing or configure microstepping. The Python library is installed with pip install servomotor, while the Arduino one is found in the Arduino Library Manager or in the Arduino_library/ folder of the project.

The command set is data-driven. Every firmware command is defined once in motor_commands.json, and from there the Python library, Arduino library and MCP server are generated. As a result, a change to the firmware propagates by itself to all the control tools, without rewriting three interfaces by hand. The firmware runs on STM32G0, with bootloader_STM32G030/ and bootloader_STM32G031/ for updating.

There is also an MCP server, servomotor-mcp, which is started with uvx -from servomotor-mcp servomotor-mcp. An AI assistant such as Claude Desktop, Claude Code or Cursor can thus drive real motors in natural language. The API documentation is generated for Python and Arduino in Markdown and PDF, and the datasheet exists in English, German, Spanish, French, Italian and Portuguese.

What you need to rebuild the test bench

Moving an M17 takes few parts: a Gearotons motor in the chosen size, a 12 to 24 V power supply capable of about 1.1 A per motor, and a USB-RS-485 adapter to connect to the host PC. Two motors are daisy-chained on the same bus, as in the bench test. The source code, firmware and libraries are in Tom Rodinger’s repository, where the command JSON files and the bootloaders are also found.

To connect the PC to the chain of motors you need a USB-RS-485 adapter: the catalogue includes a USB-RS485 converter adapter with an A/B terminal block, which acts as a bridge between the computer and the bus. Unlike a normal NEMA-17 stepper, here the driver and encoder are already inside the motor: this integration is what sets the Gearotons M17 apart.

The presentation video lasts 50 seconds and was recorded on 2026-09-09 on a bench M17. The project is meant for anyone building robots, rotary tables, CNC axes or any movement that requires precise position without wiring an external driver. Thanks to the RS-485 bus, adding a motor to the chain costs only one more cable.
