Application 168: Exoskeleton for Paraplegics

Application Summary
Spinal cord injuries (SCI) often leave the patient with little to no ability to ever walk again. The Institute for Human and Machine Cognition (IHMC) aimed to help solve that with a powered bionic exoskeleton at the 2016 Cybathlon in Zurich, Switzerland. Their ingenious exoskeleton suit, named Mina v2, utilises power actuators that strap to an individual’s legs, moving their hip, knee, and ankle joints, allowing an individual to walk unassisted.

Products in Use
Six FUTEK LCB200 In Line Rod End Tension and Compression Load Cells paired with Strain Gauge Amplifiers (IAA series or IDA100). View Product Details

Load Cell - Exoskeleton for Paraplegics
How it Works
  1. FUTEK sponsored their exoskeleton by providing our LCB200 load cells, which were installed in specialised fixtures IHMC designed, enabling the system to receive accurate force feedback from the motors and closing the control loop, all while allowing the sensor to safely rotate.
  2. A LCB200 is installed in a specialised fixture attached to the motor, allowing it rotate like a human joint, minimize extraneous loads, and provide accurate load data.
  3. As the motor operates, it applies force to the joint, rotating it. This force is measured by the LCB200.
  4. The mV/V signal from the LCB200 is sent to the IAA series analogue amplifiers or IDA100 digitally configurable amplifier.
  5. The amplified signal is sent to the exoskeleton’s control system, using the amplified load cell output to close the loop and drive the exoskeleton’s motors.
  6. With the IDA100, amplifier output can be simultaneously monitored and adjusted on a Windows PC with FUTEK’s SENSIT software while providing high speed, amplified, analogue output.
