The AIDER is a powered hip-knee gait rehabilitation exoskeleton by Buffalo Robot Tech.


This wearable robot can be used by rehabilitation clinics or help paraplegics complete basic daily activities. It offers a personalized robotic walking aid to the patient and comprehensive therapy data to the practitioners. It is designed to be used for gait training, lower limb movement and coordination training, strength training, cognitive training, and posture control training, among other things.

General functions:

  • Standing up and sitting down.
  • Walking.
  • Going up and down stairs.

Accomplished functions:

  • With the help of crutches, users can complete independent sitting (from sitting to standing, from standing to sitting).
  • With the help of crutches, users can walk along straight lines on flat ground.
  • Users can donn and doff the exoskeleton independently.
  • With the help of handrails or crutches, users can go up and down stairs.
  • With the help of crutches, users can go up and down sloped paths.
