Hortimotion is a startup company, developing automated solutions for horticultural environments. With the robot initially being developed around the cleanligh UV light, this graduation project focussed on identifying and designing a new application for the robot. This because the focus had shifted away from the cleanlight UV light, for good reasons. During the first phase of the project, the analysis phase, many methods were used to analyse Hortimotion and the users and market connected to it. This resulted in the identification of value propositions, a problem definition and a clear vision, which stated: “Designing a reliable crop spraying robot, providing the horticulturist the best crop-protection in an automated and flexible way, with the horticulturist being in control”. This vision resulted from analysing the company and interviewing horticulturists in order to find their biggest pain points. With the company lacking a clear focus and with the results from the analysis phase, it was decided to alter the assignment and focus on identifying and designing a new application for the Hortimotion robot. In the second phase, the concept phase, with the use of the lean startup methodology and validation board, experts in the field of crop protection were consulted to (in) validate the riskiest assumption, made during the first phase, which stated that low volume crop spraying would work. Both of them indicated that using low volume crop spraying technology would have huge advantages. The next step was testing the riskiest assumption from the user’s perspective, so context mapping session were held with four different horticulturists. This gave an insight into their vision of an ideal crop spraying robot and their willingness to use other techniques than what is used by them today. This validated the riskiest assumption and pivoted the solution hypothesis to designing a low volume crop spraying robot. For this solution hypothesis, the company Agricult was asked to join the effort of designing a low volume crop spraying robot, on which they replied positively. With the sharpened solution hypotheses and the inclusion of Agricult, the idea development started with formulating a design brief and organising a creative session with fellow IDE student to generate ideas from a different perspective. With the produced product ideas, a testing session was set up to (in)validate the new riskiest assumption which stated that air support would be necessary in the concept. With the conclusion that air support was indeed needed for achieving a proper spray pattern, a final concept was selected. Phase three started with a visit to Agricult, looking for any improvements that could be made on the design of the crop spraying application. With the results from this meeting and the testing session, the last assumptions could be (in)validated, pivoting the solution hypotheses into designing a single side low volume crop spraying robot with air support. With the new solution hypotheses came a name for the application, AUCROPS. Technical designing of AUCROPS’s components started with a list of requirements summing all previous conclusions. Than an effort was made to design the robot with as many “off the shelf” parts as possible, while at the same time incorporating all the aspects from the list of requirements. With the design choices explained, an energy balance was made to indicate AUCROPS has more than enough energy to spray the targeted 1/4th of an hectare. With the use of a user scenario a typical way of using AUCROPS was then illustrated. To show how this new way of using benefits the user, a customer journey was used to clearly show the benefits for the horticulturist. With the design of AUCROPS finished, the production techniques and cost were than discussed at the end of phase III. With the total sum of all components being way below the amount horticulturists are willing to pay, a healthy margin is left for building a healthy business. Finally, chapter six shows how with the use of 3D printing technology a scale model is made and what the plan is for the build of a working prototype. Both can be used by Hortimotion for further developing the AUCROPS.
