mod Who Are We?
MIT Global Innovation and Technology Research Leader, Known world-wide for building a better future for humanity.
MIT Media Lab Media Technology Incubation Center (projects include: Robotics, One-Laptop-Per-Child, Wearable Computing, Intelligent Prostheses, and Artificial Intelligence).
Smart Cities MIT Media Lab research home of the RoboScooter led by Prof. William J. Mitchell
Global Problems World Population Estimates
1. 50% of Global Population – Currently live in dense urban areas (red line)
2. Increased Urban Densification – Urbanization trend will continue for the foreseeable future (rural populations will flatten and decrease)
3. Increased Inefficient Energy Use – leading to climate change
Current Challenges South Africa
Transportation Underdeveloped public transportation system and massive congestion
Environment Carbon emissions and other forms of pollution created by extensive use of private gasoline powered 2 and 4-wheeled vehicles
Socio-economic Post-apartheid economic class division and the need to eradicate poverty in compliance with the Millennium Development Goals.
Current Challenges South AfricaTransportation Over the past 10 years, South Africa has seen its major cities sprawl, their populations grow, and traffic on the roads and rail networks explode. Existing public transportation infrastructure is being stretched beyond capacity and congestion on roads has increased.Extensive World Cup transportation plans are in place for moving players, the FIFA family, visitors and local citizens to venues, however, flexible movement options for visitors to enjoy the wider urban area need to be provided without significantly adding to existing congestion.
Current Challenges South Africa
Environment Carbon emissions and other forms of pollution are being created by the extensive use of private gasoline-powered vehicles: the majority of urban commuters use minibus taxis, and car ownership has increased dramatically with the growth of the middle class.
During the World Cup, the additional transportation requirements could dramatically increase the dependency on petrol and diesel, greatly aggravating air pollution. This could negatively impact the athletes, as was seen at the Beijing Olympics in 2008.
Current Challenges South Africa
Socio-economic As transportation infrastructure was used as a major divisional urban element by apartheid urban planners, transportation systems often continue to reinforce unequal levels of access to opportunity for most South Africans.
The investment in transportation infrastructure for the World Cup must grasp the unique opportunity to redress the prejudiced movement systems of the past, to not only meet transportation requirements during the tournament, but to leave a positive, lasting legacy, a sustainable infrastructure for all South Africans that out-lives the World Cup.
Our Solution A Mobility-on-Demand System
1. Fleet of shared-use low cost, lightweight electric vehicles placed at charging stations distributed throughout the city
2. Users pick up and drop off at any station (one-way rental)3. Unique folding electric vehicles designed specifically for one-way sharing4. Management system dynamically manages demand and vehicle supply

Democratizing Mobility Achieve social equity by creating mobility accessNo longer restrict transportation to those who can afford expensive form of private vehicle
Creating a Scooter Economy Create local employment to develop advanced electric scooter productPotential to export product to other countries
Creating an Efficient Economy Integrates various modes of transportationto optimally reduce mean travel time, volatility of travel time, cost of transportation, and frequency of congestion
Creating a Greener Economy Reduce absolute amount of energy consumptionfrom increased utilization of public transportation and eliminating the need to look for parkingReduce gasoline pollutant level within the cityPotential to significantly reduce greenhouse gas emission from alternative power generation
RoboScooter Application in South Africa
Local Knowledge Research into urban mobility problems of South African Cities
Current Problems 1. Access to transportation systems is unequal, reflecting the urban segregation of people during apartheid.
2. The state of the current infrastructure is poor, with roads becoming increasingly congested, and busses and trains overcrowded, badly maintained and often unsafe.
3. 65% of all daily commutes are by minibus taxis, which are not yet regulated and thus are often unroadworthy, overcrowded and exploit passengers. Taxi violence has been a significant urban problem over the last 10 years. 4. Intra-urban transport systems are poor, and people are not able to easily, safely and cheaply travel around the major cities, particularly at night. 5. Tourists must rely on private touring company vehicles, restricting the distribution of “tourist investment” in cities.
Specific Solution RoboScooter Mobility-on-Demand
How it fits at all levels Works in conjunction with Mass Transit Systems, Private, and Ad Hoc vehicle networks
Case Study Cape Town (see next)
RoboScooter Application in South Africa Cape Town Use Case
City Bowl: Busses, trains and taxis only go to the edge of the City of Cape Town, leaving poor connections to the rest of the city and to the new "Greenpoint" Stadium.
City Bowl: Access and connections from the Station to the major attractions and public services of the city are inconsistent and unreliable. Gradients often make walking difficult, particularly for the elderly.
City Bowl: RoboScooter to provide inner-city connections between tourist spots, hotels, civic facilities and World Cup venues.
"Greenpoint": Mobility-on-demand systems to be incorporated into existing transport infrastructure and urban structure.
RoboScooter Application in South Africa Cape Town Use Case
RoboScooter Solving the Social Issues
Social Equity
Mobility-on-Demand creates mobility access for all by connecting to current transportation and local nodes, but allowing for greater flexibility of movement to bridge transport infrastructure barriers and start to meaningfully integrate the city.
Democratizing Mobility
As RoboScooter and the Mobility-on-Demand system will support local public transportation – both formal and informal – but also has the flexibility to solve the ‘last mile problem’ (getting from the transport stop to your destination), it serves to make public transportation more attractive to all citizens, helping to achieve the critical mass of users required in providing a world-class transport system for all.
Creating a Scooter Economy
With vehicle manufacturing and assemblage skills in centers such as Port Elizabeth and Johannesburg, there is a possibility for manufacturing scooters for the African market, as well as the global market. The current hike in fuel prices has also lead to the creation of a greater market for scooters in South African cities, which could be regulated and grown by the DoT through the Mobility-on-Demand project.
What Are Others doing?
Bicycles Shared-Use Systems like Velib are spreading globally
Public Transit Incremental improvement of subway systems and implementation of bus rapid transit (BRT) systems
Private Autos Incremental improvement in energy efficient vehicles
Shared Autos Companies like Zipcar are making inroads in shared-use cars.
Existing Current Solutions & Problems
Sharing Systems: Many users share a limited number of vehicles
Two-Way Car Sharing (Zipcar): Users pick up a car from a station and return it to the same station
Problems: Non-FlexibleNeeds too much parking spacePollution
One-Way Bike Sharing (Velib): Users pick up a bike from a station and return it to any other station.
Problems: Bad Management: many stations get empty, while many other stations saturate (needs trucks to redistribute fleet)Truck redistribution is not easily applicable to heavier vehicles (scooters, cars)Requires user effort (cycling can be difficult on hilly landscapes);
Our Solution Mobility-on-Demand: A One-way Self-Correcting Electrically Powered Sharing System
1. Fleet of shared-use lightweight electric vehicles placed at charging stations distributed throughout the city
2. Users pick up and drop off at any station (one-way rental)3. Unique folding design to minimize parking space occupation4. Intelligent self-correcting management system (dynamic pricing) creates incentives to users
to efficiently allocate vehicles to stations
Our Management System Self-Correcting Dynamic Pricing
Dynamic Pricing: How it Works
Guaranteed Service at any station under a fixed maximum waiting time
Trip price depends on supply and demand: Price consists from a Pick-up, Drop-off, and Distance part. Pick-up and Drop-off parts depend on inventory needs of origin and destination station, and may vary throughout the day
Every station knows exactly how many vehicles it currently needs based on (a) long term forecast and (b) current net-flow and intelligently adjusts its drop-off and pick-up prices accordingly
Price depends on how ‘far’ is the system from the desired state
System entices users to bring it to the desired state while deters them from bringing it to an undesired state

The RoboScooter | Building a Future State
RoboScooter on the Street
The RoboScooter is also designed to be effective in one-way, shared use mobility systems, similar to the one-way bicycle rental system that has recently been successfully implemented, on a large scale, in Paris.
RoboScooter in Public Spaces
In one-way shared-use systems, RoboScooters are available in parking-and-charging racks throughout the city. When you want to go somewhere, you just swipe your credit card to unhook a scooter from its rack, drive it to where you want to go, and drop it off again at another rack. It’s like having valet parking everywhere.
RoboScooter Station
The one-way shared-use model is particularly effective in highly congested urban centers, and in synergistic combination with transit systems – where scooter racks can be located at transit stops.
Not just RoboScooters Mobility-on-Demand Station: CityCars and RoboScooters
Building a Future Smart City
With large-scale use, RoboScooters and CityCars throw enormous battery capacity into the electrical grid.
Effective utilization of inexpensive, off-peak power and clean but intermittent power sources – solar, wind, wave, etc.
A smart, distributed power generation system composed of these sources (the entire city as a virtual power plant) minimizes transmission losses.
RoboScooter Demo
RoboScooter Robot wheel
The robot wheel architecture enables the RoboScooter to be produced in both one-wheel-drive and two-wheel-drive versions. Two-wheel drive, which is complex and difficult with more traditional location of a motor, offers many potential performance advantages.
Animation: Michael Chia-Liang Lin
Folding
Folding is accomplished by means of a special central pivot, which shifts the wheels in and out of alignment as required.
Folding is automatic and powered by the wheel motors. It does not require manual effort by the user.
Electrical Power with Automatic Battery Charging
The RoboScooter is electrically powered, which means that it is silent, and has no tailpipe emissions.
Its batteries recharge automatically whenever it is parked in the special scooter rack that has been designed for it.
Because it automatically recharges in this way, it does not need very long range and it does not need to carry around a large, heavy battery pack.
RoboScooter Intelligence
The RoboScooter makes maximum use of digital control technology. This is highly synergistic with its robot wheel architecture. Its overall effect is not only to provide excellent performance, but also to simplify and lighten the scooter.
The RoboScooter is equipped with GPS navigation, and it provides a unique, single-screen display for all driver information – eliminating traditional dials and indicator lights.
