Welcome to our weblog publish! Immediately, we’ve the pleasure of introducing our visitor blogger who will probably be sharing an thrilling mission known as the HANDIWHEEL. This mission was developed by a workforce of proficient college students from Louis Armand Excessive College in Nogent-sur-Marne, France. Let’s dive into their outstanding journey and discover the progressive points of their award-winning creation.
What’s the HANDIWHEEL mission?
How did the workforce develop the concept of the deployable wheel and the way did they create it to actuality?
The workforce acknowledged the significance of overcoming sidewalks and curbs for wheelchair customers. Impressed by this problem, they conceptualized the concept of deployable entrance wheels. By using a system of deployable wheels managed by a servo motor, they devised a kinematic mechanism with 10 pivot joints. This ingenious answer allowed the entrance wheels to extend their diameters, enabling them to overcome obstacles successfully.
What instruments did the groups use to go from idea to design?
To remodel their idea right into a tangible design, the workforce employed numerous instruments and methodologies. They utilized CAD fashions and prototypes created on the faculty’s FabLab, using 3D printing for the plastic components and laser slicing for the picket facet partitions. Moreover, they adopted the Mannequin-Primarily based Design (MBD) strategy, leveraging Simulink, Stateflow and Simscape to develop fashions for motor management, sensor info administration, management the robotic actions and for sizing its vitality autonomy.

What was the workforce’s expertise going from simulation to making a prototype?
Transitioning from simulation to prototype concerned important effort and problem-solving. The scholars efficiently linked their Simulink fashions to an Arduino board, permitting them to deploy the management program for motorization and sensor info administration. Additionally they utilized Stateflow to create a state diagram, enabling exact sequencing of the robotic’s actions for impediment climbing. Furthermore, they addressed mechanical constraints by manufacturing the wheels utilizing 3D printing and laser slicing strategies. Overcoming challenges similar to meeting and rotational steerage, they discovered progressive options, together with utilizing bearings from the corporate IGUS.
Electrical constraints required particular consideration to make sure correct connections and performance between the battery, Arduino Mega board, servo motors, and motor drivers. The scholars discovered soldering strategies and numerous forms of electrical wiring to handle these constraints
To include the brand new mechanical evolutions and developments, the scholars efficiently tailored the robotic’s management program to include the brand new mechanical developments, aligning it with the mission specs. This required understanding Stateflow charts and making crucial changes to make sure the sleek operation of the robotic primarily based on its up to date mechanical design.

Conclusion
In conclusion, the HANDIWHEEL mission launched into a rare human journey. Below the steerage of their academics Pierre Rabec and Mehdi Boughriet, the workforce consisted of extremely motivated college students: Luca Fontaine, Walid Atik, Matéo Guglielmi-Lacoux, Edern Deneuville, and Illya Liganov. These college students have a ardour for science and luxuriate in tackling challenges. By way of their distinctive collective intelligence and unwavering teamwork, they introduced the deployable wheel idea to life. From CAD modeling to simulation and prototype creation, their journey exemplifies the ability of innovation and willpower. We applaud their outstanding achievements and stay up for witnessing the constructive impression of the HANDIWHEEL mission on people with mobility challenges.
