Though new technologies have been applied in all industries, electric mobility technology using eco-friendly energy is drawing a great deal of attention. This research focuses on a personal electric mobility system for urban tourism. Some tourism sites such as Gyeongju, Korea, have broad spaces for tourists to walk around, but the public transportation system has been insufficiently developed due to economic reasons. Therefore, personal mobility technology such as electric scooters can be regarded as efficient alternatives. For the operation of electric scooters, a charging infrastructure is necessary. Generally, scooters can be charged via wires, but this research suggests an advanced electric personal mobility system based on wireless electric charging technology that can accommodate user convenience. A mathematical model-based optimization was adopted to derive an efficient design for a wireless charging infrastructure while minimizing total investment costs. By considering the type of tourists and their tour features, optimal locations and lengths of the static and dynamic wireless charging infrastructure are derived. By referring to this research, urban tourism can handle transportation issues from a sustainable point of view. Moreover, urban tourism will have a better chance of attracting tourists by conserving heritage sites and by facilitating outdoor activities with electric personal mobility.

In this paper, a robotic vehicle for a personal mobility with electric-driven three-wheels is proposed. Before designing the proposed robotics vehicle, omni-directional motions using special wheels, active caster wheels, and active steerable driving wheels are studied. For design of the proposed vehicle, we discuss about active steerable wheel design, and vehicle’s frame design. The omni-directional motion through the digital design exploration of the vehicle using active driving and steering wheel robot technology is examined. As the major mechanical components, an active steerable driving wheel, in-wheel motors, brakes, suspensions, and control systems are described. The design is established by rapid prototyping model of omni-directional motion. The steering geometry and control algorithm for the prototype of the proposed personal mobility are experimented.

Engineers must consider social and environmental impacts of engineering, particularly sustainability. Student design projects should help develop this competency. A suitable theme is design to address the challenge of global warming. Personal transportation is a major contributor to greenhouse gas (GHG) emissions, and students at Western have worked for several years on the design of a Sustainable Personal Mobility System (SPMS). SPMS is a vehicle sharing system using ultralight electric vehicles (ULVs) powered by renewable energy. Western undergraduate students have developed and analysed the SPMS concept, and have concluded that it is feasible to provide convenient and cost-effective personal mobility while reducing GHG by at least 85% compared to private cars. The design of a suitable ULV would be an excellent new direction for student projects, including existing solar car teams.
