A robotic that strikes like a fish, a go well with with artificial muscle mass, a heart-lung machine for infants, and a way for spinning yarn out of used clothes – these are simply 4 of the concepts that ETH Zurich Bachelor’s college students of Mechanical Engineering have pursued as a part of focus tasks over the previous yr. On 31 Could, the groups will current their merchandise to the general public.
The MetaSuit workforce developed artificial muscle mass. Within the SURF-eDNA mission, college students developed a diving robotic to gather DNA samples. Picture credit score: ETH Zurich
For the SURF-eDNA mission, college students are growing an autonomous underwater robotic that strikes like a fish and does so nearly noiselessly.
This robotic can movie underwater and gather samples displaying which organisms reside in a given surroundings. It has a built-in filter with which it collects fragments of DNA current within the water. The robotic is propelled by a silicone fin, into which water is pumped in cycles. Because the robotic can transfer nearly silently, it may be deployed in delicate ecosystems with out disrupting them.
The scholars belonging to the MetaSuit mission need to make digital actuality (VR) a full-physique expertise: they’re growing a go well with full with artificial muscle mass.
Wearers can immerse themselves in digital worlds and get haptic suggestions – as an example, by feeling resistance on their arms. On this approach, the robotic go well with opens up new VR experiences that may very well be engaging to the movie trade in addition to to the medical sector for rehabilitation remedies.
College students of the byPulse mission take a look at their heart-lung machine in an MRI system. Picture credit score: Bypulse
The byPulse workforce are tackling an issue that arises when infants or toddlers must endure coronary heart surgical procedure. A heart-lung machine helps maintain these younger sufferers alive throughout their operation. However attaining the optimum setup for such machines shouldn’t be simple – one incorrect setting could cause lasting mind harm.
The scholars are growing a heart-lung machine that may be operated whereas blood move within the mind is monitored utilizing magnetic resonance imaging (MRI). They hope this type of monitoring will reveal what parameters should be adjusted to cut back the variety of circumstances of toddler mind harm ensuing from this type of surgical procedure.
Because the heart-lung machines presently in the marketplace comprise steel parts and electrical motors, they don’t seem to be appropriate with the magnetic subject generated by MRI machines.
College students of the ReTex focus mission with a carding machine they developed to acquire fibres from material. Picture credit score: Retex
Within the ReTex mission, college students are trying to get the clothes trade in form for a round economic system. The workforce is growing methods of recovering textile fibres from used clothes and spinning these into high-high quality yarn. As we speak, just one in each hundred gadgets of clothes is worn once more second-hand.
The remainder are both shredded to be used as insulation materials or find yourself in landfills. The workforce hopes that their new know-how will assist make the textile trade extra sustainable.
Run by Bachelor’s college students of mechanical engineering and electrical engineering, the main focus tasks present a possibility to place concept into follow.
Working in groups, the scholars have two semesters to show an thought into an modern product. They handle all phases of product growth themselves – from idea and design to fabricate and advertising and marketing. On the finish of the 2 semesters, the scholars current their tasks on the Focus Rollout.
Different focus tasks in 2022/23
- aCentauri is constructing a solar-powered racing automotive designed to finish the three,000 kilometre course on the World Photo voltaic Problem in Australia in October 2023. Along with being aerodynamic, the automotive can also be secure sufficient to resist sturdy crosswinds.
- Cellsius Project H2 is growing a propulsion system for small plane that makes use of a hydrogen gas cell to energy an electrical motor. Hydrogen opens up the opportunity of carbon-free flight, quick refuelling occasions and lengthy ranges.
- Cito Libra is growing a driverless electrical motorbike. Gyroscopes be certain that the two-wheeler stays secure. Potential future functions embrace autonomous two-wheelers and improved stabilisation for typical bikes.
- eXact is constructing a completely electrical – and thus quieter – excavator. Whereas the grappler arm on in the present day’s excavators is powered by hydraulics, the ETH workforce is utilizing electrical linear drives which are significantly environment friendly.
- Formula Student Electric is growing an electrical racing automotive to compete in System Scholar competitions in opposition to vehicles designed by scholar groups from different European universities. Named “Castor”, the workforce’s racing automotive has a completely unique design.
- magnecko is growing a four-legged robotic whose magnetic toes permit it to climb up metal constructions. The concept is for the robotic to assist with security inspections of those constructions sooner or later.
- PROMETHEUS is growing a rocket engine powered by ethanol and liquid oxygen as a part of the ARIS scholar mission. Within the subsequent few years, PROMETHEUS goals to launch a rocket powered by this engine into area as a part of a scholar competitors.
- SONANO is growing a brand new distinction materials for optoacoustics, a brand new and relatively cheap technique of medical imaging. Primarily based on gold nanoparticles, this distinction materials ought to assist make it simpler to detect tumours in breast tissue.
- swissloop is growing a Hyperloop high-velocity transport system that can allow items and folks to be transported sooner and in a extra climate-pleasant approach than by air. The scholars are constructing a brand new sort of linear motor and an energy-environment friendly floating system.
