- 1. BIGDOG- The most advanced quadruped robot on earth Samrat Ashok Technological Institute, Vidisha Presenter: Adesh Tamrakar Sch No. 27039 3rd Sem- Mechanical Seminar & Entrepreneurship ME-1737
- 2. Introduction This presentation will tell you about. • What is a Robot ? • Quadruped and quadruped robot and its need • Bigdog Robot – About – Architecture – System Specifications – Capabilities
- 3. What is a Robot ? • According to Robot Institute of America, Reprogrammable, Multifunctional manipulator • Designed to move material, parts, tools or specialized devices • Using various programmed motions for the performance of a variety of Tasks
- 4. Quadruped and Quadruped Robot • Animals with four legs. Source: Oxford Dictionary • Quadrupedalism: Terrestrial locomotion in animals using four limbs or legs. Source: Wikipedia • Quadruped Robot: Four Legged Robot – Self balancing, using sensors – Also called, Quadrupod
- 5. Need of Quadruped Robot • Earth’s half landmass is only accessible vehicles • People and Animals can go almost anywhere • Uncertain and Extreme rough terrain • Efficient Warhead • Stability, in any uncertain surface motion
- 6. Bigdog: Quadruped Robot • Four legged Robot, Developed by Boston Dynamics, funded by- DARPA. • Unmanned legged vehicles with rough-terrain mobility superior to existing vehicles. • Can Negotiate terrain with a minimum of human intervention. • Carry its own fuel and payload
- 7. Architecture
- 8. • It can stand up, squat down • Travel speed for the crawl is about 0.2 m/s • For trot is about 1.6 m/s, running trot- 2 m/s • It weighs about 109 kg, 1 meter tall, 1.1 meters long, and 0.3 m wide. • jump about 1.1 meters, carried 154 kg- flat terrain. • Longest continuous operation- 10 km hike (6.2 miles) that lasted 2.5 hours. • Climb slopes upto 35 degrees. Capabilities
- 9. System Specs • Power supply- Leopard go-Kart engine, water- cooled two-stroke Internal Combustion engine 15hp, 9000 rpm, electric Starter. • Variable displacement hydraulic pump (3,000 psi) • Custom actuator package (x16) • About 50 sensors. • Inertial sensors, joint sensors, homeostasis sensors: hydraulic pressure, flow and temperature, engine speed and temperature, and the like.
- 10. Control System • Human operator- through an operator control unit (OCU) that communicates with the robot via IP radios. • High-level Input- to steer and speed. • Start or stop its engine, stand up, squat down, walk, trot, or jog. • A visual display for operational and engineering data. • BigDog's onboard control system operate legs, provide stability, reflex responses to external disturbances.
- 11. Summary • Robot is a reprogrammable, multifunctional manipulator • Quadruped Robots have four legs, self balancing • Bigdog is the most advanced quadruped robot • Inspired from fact- Animals and human can go anywhere, unlike wheels • Capable to cope extreme terrains
