Primary target group of our product is the semi-professional part of the autonomous cleaning robot market. The ACC 3000 robot is designed with two motions and one 360-degree environment IR sensor and a recharge station with an inbuilt Wi-Fi device to monitor the robot. The robot can drive anywhere if no obstacles are detected. The ground is flat, the inclination does not exceed 5 degrees and the Wi-Fi connection is not lost. When switched on, the controller inside gets continuously updated on the health parameter, e.g., battery status and obstacle detection by the help of the sensors. The robot is controlled and can be monitored by an app on a smart phone. Simple commands, such as ON/OFF switch, route mapping and two different rotational speeds of the wire brushes are possible to set up. For example, setting up the system for higher rotational speeds of the wire brushes ensures to remove even persistent plant or moss infestation in between gaps of the ground surface. Our competitive advantage is that our cleaning robot is made of durable and cost-efficient materials and will save household costs as a long-term investment by removal of labour cost of expensive workers. There are no other autonomous cleaning robots at this price available that match our design and usability, which makes our product unique in the market. We will start production and sales in Germany with plans to later expand into the European, North American, and Asia-Pacific region. Our product pitch, design concept, and features are presented in an audio-visual format and is awarded the Science Communication ‘Gold Leaf Prize’ for an outstanding online video presentation in the category of ‘Audience Choice’ on January 18th, 2022.

The main function of our robotic cobble cleaner is to remove plant growth from the cracks between cobbles or tiles. This will be made possible by the Nylon brush roller component installed at the base of this machine. Our machine’s secondary function is to collect the plant material residue/debris after the cleaning has been done. This will be facilitated by a vacuum that will also be located at the base of the body of the robot. Regarding power supply, our robot will be powered by rechargeable batteries in its body and a charging station will be installed in the area of operation. Perimeter wires will also be laid down around the area where the robot will operate for navigation and self-charging purposes. The robot will have two ON/OFF switches. The main one is to turn it on/off and activate every function exclusive of the vacuum system and the other is to turn on the vacuum system. The decision to isolate the vacuum system from the rest of the robot was made due to sustainability and efficiency reasons. Our robot will be able to move on four wheels driven by two motors in the front, that is, front-wheel drive (FWD). Our robot will also engage the functionality offered by sensors for easy navigation and smooth operation in fulfilling its goal of autonomy. As a team, we opted to prioritize the small-scale commercial sector as our main market due to primarily financial and usability factors. After doing market research, we discovered that this market needed such a product the most and had sufficient area and capital to utilize it adequately. Regardless, our product will still be open to the other sectors in the economy, such as large-scale organisations and domestic consumers with regards to functionality and performance. Our product pitch, design concept, and features are presented in an audio-visual format and is awarded the Science Communication ‘Silver Leaf Prize’ for an outstanding online video presentation in the category of ‘Audience Choice’ on January 18th, 2022.

The robot is called EZClean-Bot. Our slogan “Always on-Always clean-Always relax” means that when you set it on for the first time, you don’t have to look after it again because it has an automatic “Return to Home” feature that allows the robot to automatically charge itself when it has done its job. The robot will also be provided continuous power from the sunlight using a Solar Panel attached on top of it. The robot will be controlled by user-friendly buttons, and it is integrated with a self-mapping system, so it will clean the whole area thoroughly without bumping and crashing into objects or humans/animals. The robot can start itself using a pre-set timer/schedule. This EZClean-Bot is integrated with strong and durable steel brushes which are attached in vertical and horizontal directions, so it can clean not only the cobble/pavement but also the grass, dust, soil, and dirt between the cobble. The brushes will be attached with a small but high torque motor and can spin up to 10000 RPM depending on the surface. The robot has 2 big motorized driving wheels at the rear and 2 caster wheels for free movement. The whole system will be energized by two Li-Ion 12V and 5V batteries and a solar panel to increase its running time. There will also be some RGB LED light strips around the robot, so it can tell some information by seeing the different light colors. In addition, the robot is included with a high-capacity container to store the dust, soil, grass, etc. so you don’t have to sweep it by yourself again. The focus of our project will be a lightweight, portable, easy to maintain, energy-efficient, safe, and durable machine in which we have all our wiring, gear, motor, brush fully enclosed in a housing that protects it from water, wind, dust, and other extreme conditions. The cost of this product will be kept as low as possible in order to reach as many customers as we could. This robot will be a middle-end robot, so its target sale will be middle-range financial residence to a small company in Europe. Lastly, our product will be produced by four intelligent engineers from different majors and specialities.

The design concept comprises of a closed loop feedback control system where light dependent resistors will be utilized as sensory components sending a microcontroller feedback signals containing information regarding the sun ́s light incident intensity. If the sun ́s light intensity decreases from a pre-specified intensity value, the microcontroller will send a signal to the relevant motor, adjusting the position of the sunshade. Two separate poles will control the movement of the sunshade. The lower pole is fixed and inserted inside a plate, rotating around its own axis dictated by a stepper motor, hence allowing rotation that follows the sun ́s natural azimuth angle. The upper pole is connected to the lower pole through a pin joint and will follow the sun ́s natural elevation angle dictated by a second stepper motor. Aluminium Alloy 6061 was chosen as our pole material due to its relatively high strength to weight ratio in addition to its durability, consequently achieving the desired portability and long lifespan of the product. Assessments conducted throughout this project proved the material’s ability to support the design structure and external loads subject to it. The structure will be foldable and be conveniently carried with a multifunction bag with simple installation steps to make the product user friendly. Initially the product will be tested in Germany and if met with success, will further expand to global markets located in coastal regions. The estimated total price for one unit is 914.99 euros.

Thus, this project aims to improve the existing sprinklers by including wind compensation. To reduce the effect of wind on the irrigation pattern, the sprinkler velocity and radius of throw need to be adapted to the wind’s velocity and direction. Our control valve box contains seven major components. Wind and rain sensors that will collect the weather conditions, an LCD where irrigation time will be displayed, additionally to a microcontroller communicating with a second MC at the sprinkler head box via Bluetooth and controlling an electrically actuated ball valve and solenoids connected to inline pressure reducers. These three latter components play an important role in supplying proper water conditions for the sprinkler by adjusting the pressure and water flow. The position of our sprinkler’s nozzle will be detected with a magnetometer and compared to wind direction. The servo motor will rotate the sprinkler and this latter will start irrigating in a 180° pattern for couple of minutes before rechecking again all the conditions. When the sprinkler nozzle is facing the wind the velocity of throw will be increased, and after it is rotated and is in the same direction as wind, the velocity of throw will be reduced, because wind is already assisting the water droplet reach its radius. If the wind velocity is larger than the threshold value, or if it is raining, the system will not start although the switch is turned on.

The package comes with two wind sensors - i.e. wind vane and anemometer, which are mounted on a pole. The pole can be placed anywhere in the garden as long as the portable sprinkler stays within a range of 100m. When switched on, the controller on the sprinkler gets continuously updated with the current wind speed and direction using wireless transceivers. The sprinkler can also be controlled through an app on a smartphone. Simple commands such as ON/OFF switch, as well as timers for autonomous watering are possible to set up. For example, setting up the system to water the garden at sunrise, which has been suggested by experts as the most effective time to irrigate plants. Morning irrigation, on the one hand, supplies the grass and plants with enough water to sustain high temperature during the daytime and on the other hand, prevents fungal disease growth and different insects from harming the plants during the night by reducing moisture. Therefore, our sustainable irrigation system not only takes into consideration water conservation, but also provides best methods for having healthy plants in a garden. Our competitive advantage is that our sprinkler is made of durable materials and will save household costs as a long-term investment with efficient water usage methods. There are no other sprinklers in Germany that match our design and usability, which makes our product unique in the market. We will start production and sales in Germany with plans to later expand into the European, North American, and Asia-Pacific region.
