How it Works

1. 1. FUTEK sponsored their exoskeleton by providing our LCB200 load cells, which were installed in specialized 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. 2. A LCB200 is installed in a specialized fixture attached to the motor, allowing it rotate like a human joint, minimize extraneous loads, and provide accurate load data.
3. 3. As the motor operates, it applies force to the joint, rotating it. This force is measured by the LCB200.
4. 4. The mV/V signal from the LCB200 is sent to the IAA series analog amplifiers or IDA100 digitally configurable amplifier.
5. 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. 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, analog output.
