Objectives of the Indy Autonomous Challenge

1. Fostering Talented Researchers: The IAC is dedicated to cultivating a pool of exceptional graduate student researchers who are tested under pressure, collaborate effectively, and address real-time challenges in high-stress environments. Over three years, the initiative has seen participation from more than 250 students, with 150 involved in the latest event.
2. Real-World Testing: The challenge provides critical insights through live testing of vehicle hardware and software in extreme conditions, capturing data on speed, vibrations, heat, shocks, and obstacles. This information is invaluable for academic research and offers feedback to industrial sponsors.
3. Civic Engagement: The event aims to spark excitement about autonomous mobility, capturing the interest of the community, government entities, students, corporate partners, and entrepreneurs.

Inspiration from Past Innovations

The inception of the IAC draws inspiration from DARPA's Grand Challenges, which catalyzed the global autonomous vehicle industry with significant financial backing two decades ago. DARPA participated in the recent AI and Automation Summit held prior to the race, unveiling a new initiative focused on physical AI and transitioning autonomy from simulations to real-world scenarios. The IAC is positioned to be a vital collaborator in this groundbreaking program.

Competition Structure

Speed Challenge

In the Speed competition, each participating team is allotted 7 minutes to complete timed laps, with their ranking determined by the average speed of their fastest lap. Teams must refrain from any human interaction with the vehicles during the race, as communication is solely conducted through the IAC race control team. They use electronic flags for the following signals:

• Green Flag: Indicates the start of timed laps.
• Yellow Flag: Advises the vehicle to slow down due to caution.
• Black Flag: Signals vehicles to return to the pits.

Passing Challenge

This head-to-head race pits two vehicles against each other on the track. The competitors alternate roles as attacker and defender and must successfully complete an overtaking maneuver within a single lap while consistently increasing their speed. Failure to complete the pass or any accidents result in immediate disqualification.

The Racecar Design

The racecars, known as IAC AV-24, are based on the Dallara chassis employed in the IndyNXT Championship Series, customized specifically for the IAC to integrate robotics hardware and computational systems. Notably, the IAC AV-24 is renowned as the fastest autonomous vehicle globally, having set a land speed record of 192.2 mph in April 2022.

Participating Teams

• Cavalier Autonomous Racing (University of Virginia)
• PoliMOVE-MSU (Collaboration between Politecnico di Milano, Italy, Michigan State University, and University of Alabama)
• TUM Autonomous Motorsport (Technische Universität München, Germany)
• KAIST (Korea Advanced Institute of Science and Technology)
• Unimore Racing (University of Modena and Reggio Emilia, Italy)
• Autonomous Tiger Racing (Auburn University)
• Purdue AI Racing (Purdue University)
• AI Racing Tech (Collaboration among Universities of California at Berkeley, San Diego, Hawaii, and Carnegie Mellon)
• IU LUDDY (Indiana University)

Strategic Development

Teams are tasked with creating sophisticated software capable of:

• Understanding and interpreting the surrounding environment.
• Simulating vehicle-road interactions accurately.
• Determining the precise position of the vehicle.
• Planning optimal path trajectories.
• Executing timely control actions.

This must all be accomplished while operating at speeds nearing 150-185 mph. The volume of data generated by sensors each second is enormous, necessitating rapid evaluation to make instantaneous control decisions.

Speed Competition Overview

The race takes place on a 2.5-mile oval track, where an average lap is completed in approximately one minute. Teams have a total of 7 minutes for the speed competition, allowing them to run about 7 laps.

The TUM team was the first to race following a delay due to rain, achieving an average speed of 166 mph before suffering a loss of control and crashing. The ultimate victor in this competition was the Cavalier team from the University of Virginia, reaching an impressive maximum speed of 184 mph, thus becoming the first U.S. team to earn this accolade.

Passing Competition Results

Following the crash that sidelined TUM's vehicle, five teams continued in the Passing competition. The tension was heightened as AI Racing Tech encountered mechanical issues while trying to pass Unimore, who ultimately triumphed in that round.

The Italian finale featuring PoliMOVE-MSU against Unimore proved to be fiercely contested, with PoliMOVE-MSU emerging victorious.

While an event where robotic racecars compete on a closed circuit might sound monotone, the IAC presented an electrifying experience. With around 1,500 spectators and 150 competitors, this event highlighted the thrilling intersection of human ingenuity and technological advancement.

The insights gained from this event promise to have profound implications for creating agile and adaptive autonomous systems, impacting areas far beyond conventional transportation.
