Upper Limb Assistive Device

(FEA:Flexion - Extension - Assistance arm)

 This power assist device aims to reduce burdens of caregiver and use for rehabilitation of the disabled.
 And now, we apply this device to develop a new upper limb exoskeleton.

Characteristics:
1. Electromyograph
2. Robot arm with 2 DOF
3. RealTtime-Linux

Our Power Assistive Device


Without Assistance

With Assistance




Wearable Upper Limb Assistive Device

(FEA2:Flexion - Extension - Assistance arm 2)

 FEA2 is developed for reducing burdens of caregiver like hard labor, holding a care-receiver, and so on. FEA2 can assist 30% of the power to user with 70kg of the load.
 We are doing a lot of research and development for commercialization of the device.

Characteristics
1. Lightest weight in the world(Approx.5kg)
2. Easy to wear 
3. A wide movable range

Electromyograms of wearing FEA2/not wearing FEA2

 At the experiment of carrying tank of 8kg, we researched the percentage of assistance of FEA2. At the result, the data shows a 40percent decrease in both arms’ EMG comparing with the assistance of FEA2 and without the assistance of FEA2. So the effectiveness of FEA2 has been checked.
