IHMC's experience competing in the Cybathlon compared to the DARPA robotics challenge

Area of Science:

• Robotics
• Human-Computer Interaction
• Assistive Technology

Background:

• Research and development for competitions like the DARPA Robotics Challenge (DRC) and Cybathlon differ significantly from typical scientific investigations.
• This commentary contrasts the Florida Institute for Human and Machine Cognition's (IHMC) experiences in preparing for and competing in the Cybathlon versus the DRC.

Purpose of the Study:

• To discuss the IHMC's experience preparing for the Cybathlon.
• To contrast the development process for the Cybathlon with that of the DRC.
• To highlight the impact of a human-in-the-loop system on development and perception of work.

Main Methods:

• The Cybathlon's human-in-the-loop approach necessitated a different development strategy compared to the DRC.
• For Cybathlon, development focused on creating stable, unchanging motions for pilot training, making simulation less critical.
• The DRC relied heavily on physics-based dynamic simulation for both algorithm developers and robot operators.

Main Results:

• The Cybathlon was characterized as an athletic challenge for the human pilot assisted by technology.
• The DRC was framed as a robotics challenge assisted by a human operator.
• The development approach for Cybathlon prioritized pilot training and stability over complex robotic autonomy.

Conclusions:

• The Cybathlon experience was rewarding, motivating the team with the potential to improve quality of life for individuals with disabilities.
• Engineering competitions like Cybathlon accelerate development, engage the public, and raise awareness for people with disabilities.
• Powered exoskeleton technology is still in its early stages, with significant potential for improvement as an alternative to wheelchairs.
