  1. Nature Inspired Premise Validated Mission Required Legged Squad Support System (LS3) Pre-BAA Brief JUN 08 Robert Mandelbaum Tactical Technology Office PRE-DECISIONAL – INFORMATION SENSITIVE Distribution authorized to U.S. Government Agencies only (Critical Technology) (6 May 2008). Other requests for this document shall be referred to Defense Advanced Research Projects Agency, Technical Information Office.

  2. Program Objectives Carry 400lb of squad equipment 1 or 2 for a USMC squad or Army Fires Squad Keep platform squad sized for dismount maneuvers Volumetric, weight, power, relevant payload constraints Maintain large strength margin for long endurance Provide mobile auxiliary power Sense and negotiate terrain Perception on bouncing platform Select gait and place feet based on perception of terrain Follow a soldier 5-100m ahead or behind Dynamic environments Complex environments with many occlusions Maneuver nimbly Multiple gaits coupled to perception and terrain Robust stability for all gaits and gait transitions Operate quietly when required, efficiently for endurance LS3 is a technical solution to a most critical challenge for modern dismounted warfare: Weight and equipment burdens imposed on the dismounted squad PRE-DECISIONAL – INFORMATION SENSITIVE

  3. Vision:Change what we bring to the fight Goals • Give the squad platoon-level capability and equipment • Increase mission effectiveness of dismounted squads • Bring more to the fight • Critical supplies - ammunition, medic equipment, water/food • Heavy weapons, mortars & rounds, ladders, forced entry gear • Equipment usually in tactical vehicles - Comms amps/radios, battery chargers, tactical network gear (e.g. Blue Force Tracker – brings it to squad tracking) • Matched to the size and maneuverability of a dismount • Simple, intuitive command and control Fundamental issues • Platform – integration, mechanical integrity, noise mgmt. • User Interface – perception, following, interaction, dynamic scenes • Control – stability, actuation sequences, placement, gaits Goal is achievable • Big Dog has demonstrated the feasibility of military-relevant legged platforms • Key platform sub-components mature • Fundamentals of perception demonstrated in less challenging environments

  4. Program goals

  5. Conclusions • LS3 will be a military relevant system prototype • 400lb payload carrying system - doable at approximately 1,250lb total weight • Maneuver and endurance of dismounted squad • 20 miles in dismount terrain – rugged, complex, dynamic at times • 24 hours without refueling • Program will design, develop, and integrate a mission-relevant legged system composing of user interface, control, and platform elements • Received Approval for BAA release – 6 MAY 08 • BAA release – Summer 2008 • 90 day response period • 1 performer from proposals, single design & build phase • Program selection and approval of performer – Fall 2008
