In the past year, third-year MET students have undertaken a significant design project aimed at creating a new product that holds tangible business potential. To meet a customer need, they conducted market research, came up with unique design ideas and formulated a comprehensive business plan.


The project is a major examinable component of the IfM’s 3rd year MET undergraduate course, for which students develop a new product with real business potential.


Below are some exciting new ideas and innovative technologies that were generated for the 2023 projects:


Automated Pottery Machine



An automated pottery machine for use by disabled people and to educate beginners on the practicalities of manufacturing pottery; following further R&D, this will include an integrated system to convert CAD into accurate clay models.


Our proposed innovation is an automated pottery machine which offers a manufacturing process which is accessible to the needs of disabled people and teaches beginners the fundamental principles of pottery manufacturing. Clay being a more sustainable material than many others used in current manufacturing, our aim is to make its use as widespread and accessible as possible. The physical features of the machine are designed with this goal in mind; the machine features two axes to allow for the 2D movement of a grooving tool, pusher mechanism and modelled fingers, equipped with a tool change function. Interchangeably sized modelled hands also operate within a single axis separately to these tools, to form the curved shape of the pot. Working together, these tools allow for the shaping of clay on a pottery wheel.

We foresee a diverse range of practical applications for our device.


In particular, it could be enhanced by a comprehensive education program to teach beginners the fundamental potting techniques. This would be for use in schools and education centres to teach people about the use of clay and methods for its implementation. An integrated system to convert computer-aided designs into accurate clay models will form part of an efficient and user-friendly machine which prioritises inclusivity and accessibility in a manner beneficial to the individual user and the pottery industry. The automated pottery machine allows those who aren’t physically capable of the intensive physical work required in pottery making to design and produce their own pottery creations.

Carving Waves CNC


The Carving Waves CNC machine utilises a curved hot wire to cut large sections of foam and add sculpted profiles to the surface of the foam board.


The Carving Waves CNC is a 4-axis hot wire foam cutter which has been produced to aid the surfboard manufacturing industry; it could be used by major manufacturers as well as individual hobbyists, by converting CAD designs into programming code.

Surfboard manufacturing has long struggled with issues such as excessive waste generation and labour-intensive processes. Traditional shaping methods require manual skill and produce a harmful by product of foam particles, which negatively impact the environment and can cause respiratory problems after prolonged exposure.


The Carving Waves CNC has been designed to remove the issue created by foam dust, by using automated hot wires which will cut through the material in the desired shape, with the innovative curved wires being able to create curved concave profiles.


The speed of operation is much faster than the traditional method, and provides operators with the creative freedom to edit and prototype their designs much more efficiently and safely. The small amount of smoke produced by the burning of the foam is incomparable to the dust inhaled by the previous method and could be removed easily using an extraction system.


Compared to traditional shaping methods, the CNC hot wire cutter boasts numerous advantages, including increased efficiency, reduced waste, enhanced precision, and improved safety. Furthermore, the machine’s digital capabilities unlock endless design possibilities and customization options for surfboard manufacturers, catering to the diverse needs of surfers worldwide. The Carving Waves CNC is not merely a tool, but a game-changer, setting new standards in surfboard production by merging creativity, functionality, and sustainability.

With our innovative reforesting robot, we are harnessing the power of robotics to build a future with more biodiversity, more renewable resources, more carbon capture - more trees.


One of the most widely promised ways of tackling climate change is planting trees, but governments are failing to keep up with their own targets. The UK is currently only matching 30% of its planting goal of 120 million trees annually by 2025, and schemes across the world are facing issues of poor planting, lack of biodiversity, and diminished durability of forests. There are also numerous safety risks to manual planting methods, with 22 out of every 100 workers on farms incurring injuries from heavy lifting and repetitive strain.


But we’re here to help.


With its automated planting system, our robot can help achieve more consistent planting, fewer injuries, enhanced data collection and increased planting rates. The robot will include an auger to drill holes, a storage and plant delivery belt to place plants in the ground, and onboard electronics that can drive and track planting. With design features like wide wheels that can cope with rough terrain, a plant delivery mechanism that can hold up to 50 plants, and integrated food pellets to increase the plant’s chance of survival, Grover is a game changer.


As well as selling the robot to reforesting schemes and projects, we have identified a market for selling this product as a service to small-scale reforesting projects. There is also scope for selling carbon credits from the trees we plant.

HydroHelper offers a solution for removing weeds from water surfaces. Aimed for medium-scale rivers and ponds, it provides a low-cost solution more suitable than current offerings.


This project has been inspired by us through learning about potential hazards of floating invasive plants to locals at Cambridgeshire. At Cambridge, floating pennywort is a particularly hazardous plant that can cover the River Cam from March to August. The rapid growth of such weed can be detrimental to the river ecosystem and can affect vessel navigation. Fortunately, the community is filled with passionate locals to volunteer the clearing of such weeds through a labour-intensive process. Seeing as this is a highly laborious task, we hope to create a solution that can mechanise the process as a way to improve the local environment.


Our solution is a remote-controlled device equipped with a conveyor belt to collect floating debris at the front of the device. As the machine propels forwards towards the floating weeds, the raking tool on the conveyor transfers and deposits the plants onto the on-board storage system. The operation can be controlled by an operator on shore through intuitive controls similar to a remote-controlled boat. Due to this design choice, the result of a smaller-sized device allows for increased agility to cruise through narrow channels. Furthermore, for future development, specialised raking tools can be attached to the front of the conveyor to expand the use of the product for other purposes, such as rubbish and oil spill collection.


With increasing social awareness on the environmental impact of businesses, companies increase their focus on environmental, social, and governances (ESG) considerations in their daily operations. Hence, we envision a growing market for products that can maintain a sustainable environment. Therefore, we foresee this product to initially be servitised through contractual cleaning services for businesses, where then we can continue to expand operations to provide product-with-service offerings.

HaptoRead is a refreshable braille display that converts digital text into a tactile braille form in one device, to enable easier access to reading for children in visually impaired schools.


In 1960 50% of people registered as blind or visually impaired were proficient in braille. Today this has now dropped to 7% due to budget constraints on learning tools and teachers. From the 85,000 blind adults in the US alone, 90% who are braille literate are employed compared to the 33% employed who never had the opportunity to learn braille. HaptoRead’s mission is to tackle this gap at the start of education, in order to help young students become more employable, more independent and widen their opportunities in life.


 Our design converts digital text from online sources into a tactile readable form, removing the need for specialised printed braille. The HaptoRead can be plugged into any device and download text online which is then converted into the signal output of the braille characters. The user can then read at their own pace, turning to the next line whenever they are ready. This allows learning right from the beginner to advanced stages. Using a series of wheels with the different braille characters on its upper faces, a stepper motor turns each respective wheel to the desired location which is then locked in place by an actuator. This allows the process to be refreshed with each line of braille needing to be read.


To allow easy access to learning braille for children, we aim to keep our product low cost and with a simple design. Starting in the 35 specialist schools in the UK for the visually impaired, the growth of our target market can reach not only other schools globally, but also charities such as the RNIB.


Giving children the ability to learn braille will increase their opportunities for reaching their career goals, provide larger access to information and literature and provide literary independence.

The CoCollector is a remote-controlled device designed to climb and harvest coconuts from coconut trees, providing a safer and more ethical solution to traditional coconut farming in a fast-growing market.


Coconuts are currently predominantly grown in Asia and the Pacific in countries such as Thailand, Sri Lanka, and the Philippines. The coconut industry is witnessing growing demand as we incorporate an increasing variety of coconut-related products in our diets and daily lives, resulting in a projected market size of $7 billion by 2028, a significant increase from $4 billion in 2023. Meanwhile, coconut pickers are harder to come by (deemed a dying tradition by many), and farmers are resorting to unethical methods of training monkeys to collect coconuts as an alternative. Currently, farmers and monkeys will scale these trees (that grow up to 30m tall), often without a harness, and manually collect the coconuts. This practice is unsafe and leads to dozens of deaths yearly.


The CoCollector seeks to solve this two-fold issue by partially automating the coconut-collecting process. The machine’s climbing and cutting mechanism can be controlled by a farmer located at the base of a tree using a remote control. This proof-of-concept is a 2/3-scale model of what a final product may look like. Future design iterations could include partial automation using computer vision and integrating a fully automated network of these machines to manage all the trees in a plantation.


Our initial target customers are coconut farmers in Thailand, where the unethical use of monkeys is most prevalent. The machine has scalability into other countries where coconuts are grown and can further be horizontally differentiated into other tree-growing fruits.


We envision the CoCollector as a stepping stone into a safer, more ethical, and sustainable source of farming for a growing industry.
