Self-driving golf carts

Standard

Cambridge, Massachusetts – At the International Conference on Intelligent Robots and Systems in September, members of the Singapore-MIT Alliance for Research and Technology (SMART) and their colleagues will describe an experiment conducted over six days at a large public garden in Singapore, in which self-driving golf carts ferried 500 tourists around winding paths trafficked by pedestrians, bicyclists, and the occasional monitor lizard. The experiments also tested an online booking system that enabled visitors to schedule pickups and drop-offs at any of 10 distinct stations scattered around the garden, automatically routing and redeploying the vehicles to accommodate all the requests. “We would like to use robot cars to make transportation available to everyone,” says Daniela Rus, the Andrew and Erna Viterbi Professor in MIT’s Department of Electrical Engineering and Computer Science and a senior author on the conference paper. “The idea is, if you need a ride, you make a booking, maybe using your smartphone or maybe on the Internet, and the car just comes.” The researchers asked participants in the experiment to fill out a brief questionnaire after their rides. Some 98 percent said that they would use the autonomous golf carts again, and 95 percent said that they would be more likely to visit the gardens if the golf carts were a permanent fixture. SMART is a collaboration between MIT and the National Research Foundation of Singapore. With lead researchers drawn from both MIT and several Singaporean universities — chiefly the National University of Singapore and the Singapore University of Technology and Design — the program offers four-year graduate fellowships that cover tuition for students at the affiliated schools, as well as undergraduate and postdoctoral research fellowships. Joining Rus on the paper are Emilio Frazzoli, a professor of aeronautics and astronautics at MIT; Marcelo Ang, an associate professor of mechanical engineering at the National University of Singapore; and 16 SMART students, postdocs, and staff members, from both the U.S. and Asia. Less is more What distinguishes the SMART program’s autonomous vehicles is that “we are taking a minimalist solution to the self-driving-car problem,” Rus says. “The vehicles are instrumented, but they are not as heavily instrumented as the DARPA vehicles [competitors in the U.S. Defense Advanced Research Projects Agency’s autonomous-vehicle challenge] were, nor as heavily instrumented as, say, the Google car. We believe that if you have a simple suite of strategically placed sensors and augment that with reliable algorithms, you will get robust results that require less computation and have less of a chance to get confused by ‘fusing sensors,’ or situations where one sensor says one thing and another sensor says something different.”
