Autonomous Mobility for Military Scout Vehicles and Potential Driver Assistance System Spinoffs Scott Myers, President General Dynamics Robotic Systems Richard Bishop Richard Bishop Consulting May 1, 1999 @ ITSA Boston
Military Needs • Unmanned vehicles: core resource for 21st century armed forces • Robots act as force multipliers • Robots replace humans in high-risk situations • Soldiers supervise several robotic systems, leveraging available (and scarce) manpower
Demo III Program • Focus: develop, demonstrate, and experiment with unmanned scout vehicles • Sponsor: US DOD Joint Robotics Program • Manager: US Army Research Lab (ARL) & Tank-automotive Research, Engineering, and Development Center (TARDEC) • Funding: $50M during 1998-2001 • Follows Demo I (1980’s) and Demo II (early 1990’s)
Demo III Technical Elements • (1) Concerted Technology Thrust -- developing advanced technology for autonomous mobility • (2) Modeling/Simulation/Experimentation -- examining the impact of this technology on military operations • (3) Technology Integration -- Integrate technology into 4 testbed platforms: Experimental Unmanned Vehicles (XUVs)
General Dynamics Robotics Systems • Advanced manufacturing / engineering, automation/sortation/process control electronics, image processing inspection, & robotic-content products for commercial customers • Leader in the development of robotic and autonomous systems for DoD tactical and security applications • MDARS-E system: advanced autonomous vehicle for perimeter security • Robust Obstacle Avoidance System • Precision GPS-based Navigation System • Intrusion Detection System ( radar and image based target acquisition and tracking) • Interconnected via Controller Area Network (CAN) Local Area Bus • Prime Contractor / System Integrator for Demo III
Demo III Supporting Team • Sarnoff Laboratories • SAIC Center for Intelligent Systems • NASA Jet Propulsion Laboratory (JPL) • National Institute of Standards and Technology (NIST)
Demo III Program Goals • Enable small, survivable unmanned vehicles (XUVs) to tactically maneuver over rugged terrain • Maneuver at speeds comparable to manned vehicles, employing similar behaviors as manned missions • Implies significant obstacle detection smarts (both positive and negative obstacles)
Demo III Technology: Perception for Autonomous Mobility • Requirements call for: • on-road mobility (40 mph) • off-road mobility (20 mph) • day / night operations • inclement weather • stealthy operation (hug tree lines, etc.) • Must detect, classify, and intelligently respond to positive/negative obstacles: • Examples: • On-road: vehicles, people, animals, road edges • Off-road: trees, bushes, rocks, ravines, wire fences, overhanging branches
Intelligent Perception: Sensors • Passive: • Color CCD camera • Stereo high resolution monochrome cameras • Stereo infrared cameras • Both on pan/tilt mechanism • Active • Laser Scanner / LADAR (high speed, high resolution ranging) • Foliage Penetrating Radar (2.5 - 3.5 GHz) • Millimeter-wave FMCW scanning radar • (product of NHTSA research!)
Demo III Technology: Software Architecture • Intelligent software architecture • Enables complex, real-time decision making combined with a priori knowledge (maps, etc) • NIST 4-D / RCS Reference Architecture • All intelligent activity broken down into: • observation (sensory processing) • registration of observations into knowledge database • value judgement (compute costs/risk of alternatives) • behavior generation
Demo III Technology • Navigation • using P/Y code military GPS, inertial referencing, and wheel encoders • Vetronics (vehicle electronics) • plug-n-play approach • fly-by-wire vehicle controls • standard Controller Area Network (CAN) bus structure • Reconaissance Module • Enables detection of targets and target designation • Sensor suite includes camera, FLIR, laser rangefinder, acoustic sensors
Demo III: Demo Alpha • September 1999 -- initial program demo • Aberdeen Proving Ground (modest terrain) • Capabilities shown to military VIPs: • Two XUV vehicles operated by troops • 20 mph on-road, 10 mph off-road required (exceeded) • Successful detection / avoidance of rocks, poles, trees, roadside signs • Negative obstacle detection not implemented • Stereo vision (using active gaze control) very effective
Demo III: Demo Bravo • October 2000 at Ft. Knox, Kentucky • Very challenging terrain, more realistic military situations • Extensive troop usage; engineers “in the background” • New capabilities: • Road following, convoying, negative obstacle handling • Sensor suite: MMW radar, foliage-penetrating radar, stereo infrared and visible-spectrum cameras, laser rangefinder
Demo III: Spinoffs to Intelligent Vehicles for Transportation • Demo III represents the largest federal investment in advanced vehicle technology • Program provides advanced technology which can support goals of USDOT IVI and vehicle industry: • collision warning / avoidance • driver assistance systems • automated vehicle systems • Also applicable to non-highway industrial vehicles
Demo III: Spinoffs to Intelligent Vehicles for Transportation • Intelligent Perception: • approaching machine intelligence which can perceive and classify surroundings at human levels • Obstacle Detection: • typical roadway obstacles as well as potholes • Low Speed Automation (Stop-n-Go): • initial application of automation? • Electronic Towbar (heavy truck convoying): • Military already considering transferring Demo III technology to truck operations
Demo III: Spinoffs to Intelligent Vehicles for Transportation • Transit Bus Electronic Guidance: • understanding of complex urban street scenarios • Sensor Fusion: • Multiple modality sensor suites essential to IV’s • Sensor Testbed: • Evaluating a wide range of sensor types • Architectures: • direct transfer to in-vehicle architectures
Conclusion • Demo III leading technology development for super-smart vehicles • Overall robotic vehicle program focus expected to grow dramatically within DOD • Demo III funding increases under discussion • Future Combat Vehicle development beginning • Robotics Alliance being established • Information Sharing • Periodic program updates available at www.ivsource.net • Or send email to RichardBishop@mindspring.com
