MARTY Drifts Figure 8s

June 16, 2018 || Jonathan Goh / Dynamic Design Lab
The Dynamic Design Lab's autonomous electric DeLorean, MARTY, repeatedly executes a highly dynamic figure 8 drifting maneuver. During the rapid transitions between +/- 40 degrees of drift angle, the vehicle steers lock-to-lock in about a second, reaching yaw rates as high as 120 deg/s. This new version of the controller uses real-time estimation of friction and other vehicle parameters to improve accuracy and robustness. The motion plan is formulated using a nonlinear optimization scheme that takes into account both the highly coupled dynamics and limited actuation.

Stanford's autonomous car, Shelley, speeds around track without driver

February 29, 2016 || Stanford News Service

By testing the physical limits of speeding cars, Stanford engineers hope to develop safer autonomous driving systems. Shelley nears speeds of 120 mph as it tears around a racetrack. See the Stanford News article for more information.

Introducing MARTY, Stanford's self-driving, electric, drifting DeLorean

October 20, 2015 || Stanford News Service

Stanford engineers built an autonomous DeLorean capable of stable, precise drifting at large angles in order to study how cars perform in extreme situations, which could ultimately guide the development of autonomous safety protocols. Please see the article for more information.
