Engineering firm Scheurer Swiss GmbH has used its 3D printing experience to assist a gaggle of ETH Zürich college students develop their “Rowesys” automated robotic weeding system.
Working with the Zurich group, Scheurer Swiss equipped and produced a number of 3D printed carbon-reinforced elements, which enabled the robotic’s building, and enhanced its efficiency. The compact weed killing bot, which is now getting into remaining testing, has been designed as a sustainable various to using environmentally-damaging herbicides in agricultural farming.
“We supported the Rowesys group with our know-how within the subject of fibre composite applied sciences in an advisory capability. Operationally, we integrated our a few years of experience from the event of extremely environment friendly composite elements for motor sports activities, into the event and 3D printing of the carbon-reinforced elements for the agricultural robotic,” stated Dominik Scheurer, CEO of Scheurer Swiss GmbH.
Additive options to environmental issues
Whereas herbicides provide a time and cost-effective weed killing resolution to farmers, their use has more and more been linked to environmental injury. In Switzerland for example, measurements have proven contaminated floor water in nearly all areas containing agriculture. At present the one viable various method to standard farming, is opting to go natural as a substitute. This farming approach is extra sustainable, however requires further work, and might typically drive up client costs whereas reducing buyer demand. Consequently, what was wanted within the eyes of the Zurich group, was a brand new herbicide-free and economically-viable resolution.
Enter the robotic weed killer. The Rowesys autonomous weeding robotic makes use of imaginative and prescient sensors to determine and destroy weeds, with out the necessity to overuse herbicides. Created by a group of ten extremely motivated college students, eight skilled coaches and their sponsors Scheurer Swiss, the bot represents a user-friendly and environment friendly weed killing resolution. Furthermore, the undertaking demonstrates how injury to the setting might be minimised with the implementation of digitisation and 3D printing expertise.
“What motivated me about this undertaking, other than the relevance of what I discovered and the possibility to realize sensible expertise in teamwork, was the sustainability of herbicide-free sugar beet cultivation,” stated Nico Burger, Software program & Controls Group Rowesys. “As a result of thus far, there was no funding in additional sustainable manufacturing on this space of agriculture.”

Challenge Rowesys: 3D printing the weed killer
As a gold sponsor of the analysis group, Scheurer Swiss supplied its engineering experience to the group, and 3D printed carbon-reinforced elements for the robotic on their behalf. 3D printing these components not solely supplied price effectivity and design flexibility advantages, however enabled the group to fulfill the robotic’s reliability, autonomy and security necessities as nicely.
For instance, the agricultural robotic options 3D printed wafer-thin carbon-reinforced plastic slats which might be backed by LEDs, indicating the robotic’s standing always, and permitting the group to work safely round it. The autonomous weed killer additionally makes use of a 3D printed lattice-like half, which serves as an interface between the aluminium chassis and the robotic’s electronics. Utilizing AM, the weird form of the connector might be produced in such a method that not a single gram of superfluous materials is used.
Not solely does this maintain the robotic light-weight and add to its sustainability credentials, however the part stays ultra-stable throughout use, enabling it to keep up the connection throughout use. “Solely with the expertise of carbon-reinforced 3D printing is it even doable to provide such a exactly becoming, filigree and but secure part,” added Scheurer.
Within the remaining product, the agricultural bot is able to pulling small ploughs by means of the soil, which destroys the weeds between the rows of crops, by pulling the roots as much as the floor. As well as, the robotic is ready to drive autonomously, detect the tip of the sphere with the assistance of its built-in cameras, and swap to the following untilled row. Following preliminary testing which concerned sugar beet farming, the bot was discovered to be able to repeating the method, whereas dramatically decreasing the quantity of air pollution brought about by utilizing dangerous herbicides.
“The main focus undertaking Rowesys is an instance of how digitisation and using progressive supplies can produce environment friendly and clever technical achievements,” concluded Scheurer. “We congratulate the Rowesys group on their success and are happy that we have been capable of assist the group with our experience in an advisory and operational capability proper as much as the sensible check.”

ETH Zurich’s additive improvements
Within the final yr alone, researchers from ETH Zurich have used 3D printing to reinforce the qualities of all kinds of end-use supplies. In June 2020 for example, a Zurich analysis group developed a novel common nanocarrier ink platform, which facilitated the formulation of biofunctional inks. Functions for the fabric’s distinctive custom-made biofunctionality, included tissue engineering and drug supply, in addition to superior biomaterials.
In December 2019 in the meantime, Swiss-based scientists efficiently 3D printed glass objects utilizing a specialised resin and Digital Gentle Processing (DLP). The tactic proved able to creating advanced glass components, with excessive spatial resolutions and multi-oxide chemical compositions.
Equally, in August 2019, a special group of Zurich researchers developed an additive manufacturing-based process to make magnesium scaffolds with common porosity. Utilizing a 3D printed salt template, the group’s methodology managed to create magnesium constructions with ordered pores whereas retaining their mechanical stability.
