Guard Robots for Social Security- Researchers
- Byeong-Sang Kim (Ph.D. lovidia@gmail.com), Ki-Seok Kim (Master)
- Research Background
- The use of robots is increasing in various areas related to security, such as crime prevention, rescue, and reconnaissance.
- This requires high mobility to overcome a obstacles and cope with different situations.
Jumping Guard Robot: Guardian- Research Objectives
- Development of a portable guard robot capable of jumping.
- Small size and light-weight ⇒ Portable and throwable .
- Overcoming obstacles, traps, pools, etc.
- Durability against shock and impact.
- Guardian
- Size: 15cm(D)x30cm(L)
- Weight: 3kg
- Jump height: 20cm
- Max. speed: 2m/s
- Sensors: 3-axis acceleration sensor, 3-axis gyro sensor, PSD sensor
- Jumping Mechanism
- Jumping mechanism based on a conical spring and clutch mechanism.
- Conical spring: A resentative nonlinear, hardening spring.
- Clutch mechanism: Based on a planetary gear trains and one-way clutch.
- Stair Climbing
- Most difficult obstacle for small-sized robot.
- Size of the stair: 20cm(H) x 30cm(D) x 50cm(W)
- Patrolling
- Most popular application for social security robot.
