5. HOW IT WORKS: HYBRID CONTROL SYSTEM
Hybrid Control System (Cybernic Autonomous Control + Bio-Cybernic Control)
Cybernic Autonomous Control System
Two control algorithms to provide physical
support to wearers in various conditions.
Bio-Cybernic Control System
Control system that sense wearer’s motion
and activities using bioelectrical signal
including myoelectricity
Wearer receives physical support directly
from the bioelectrical signals driven motors

6. HOW IT WORKS: BIO-CYBERNIC CONTROL
1. Brain sends ‘Myoelectrical’ signal to muscles.
2. Bioelectrical
sensor detects the
signal and activates
Biocybernic Control
3. Biocybernic
Control reads
data and activates
the suit’s motors

7. APPLICATIONS
 Next generation rehabilitation
o Enhance and support physical capabilities of
the user.
o Accelerate wearer’s daily activities and
improve recovery.
o Support self-physical training
 Disaster Relief activities
o Rescue support at disaster sites
o Accelerate disaster recovery activities
and save lives
o Lifting heavy obstacles, victims and
elderly
o Disaster cleanup
7

8. APPLICATIONS
 Heavy industries
o Support carrying heavy machines and
parts
o Reduce injury due to improper
handling of heavy items
o Help ease the workers and increase
productivity
• Hospitals and nursing homes
o Improves the mobility of elderly and
disabled
o Carry patients effortlessly by nurses
and hospital staffs
o Nurse-free walking and other physical
activities

9. APPLICATIONS: DEMO

10. APPLICATIONS
 For robot-assisted therapy: Testing on stroke patients shows that robotassisted therapy is as good as intensive comparison therapy.

15. IMPROVEMENTS – BIOELECTRICAL SENSING
Bio-Cybernic Control System
- HAL exoskeleton moves
according to the thoughts of its
wearer.
- Muscle movements are based on
nerve signals sent from the brain
to the muscles – signals that are
registered in very weak traces on
the surface of the skin.
- HAL identifies these signals
using a sensor, sends a signal to
the suit’s power unit and
computer control the movement
of the robotic limbs along with
the human limbs
