Transcript

Read and summarize the transcript of this video on Glasp Reader (beta).

Summary

In this video, the speaker discusses how humans are naturally efficient at walking, but carrying heavy loads can disrupt this efficiency and cause muscle fatigue or injury. They explain that at Harvard, they study the biomechanics of human walking to understand its efficiency and then apply this knowledge to the design of software and robots that mimic the function of muscles and tendons. The goal is to assist healthy individuals and those with physical disabilities in improving their mobility. The speaker emphasizes the importance of developing wearable systems that can provide the right level of assistance at the right time, and discusses the use of soft and integrated sensors to monitor forces and movements. They highlight the progress made in human-machine interaction, including working in uneven terrain and avoiding obstacles. The speaker also mentions the development of lab-based equipment for studying the biomechanics and physiological implications of using these systems. They conclude by expressing excitement about the potential applications of this technology for the elderly, military, first responders, and athletes.

Questions & Answers

Q: What are the challenges humans face when carrying heavy loads during walking?

Humans can experience muscle fatigue and tendons can become injured when they carry heavy loads during walking.

Q: What is the focus of the research at Harvard?

The research at Harvard is focused on studying the biomechanics and physiology of human walking to understand its efficiency and apply that knowledge to design software and robots that mimic the function of muscles and tendons.

Q: How is the goal of improving mobility achieved with soft exosuits?

Soft exosuits are designed as wearable garments that are close-fitting and comfortable. The structure of the textile and load paths mimic the function of underlying muscles and tendons. Force application in the suit acts in parallel with biological muscles and tendons, providing small amounts of assistance to positively impact mobility.

Q: Where are the batteries and motors of the soft exosuits mounted?

The batteries and motors of the soft exosuits are mounted at the waist, and cables are used to transmit forces to the joints.

Q: What is the importance of providing the right level of assistance at the right time in wearable robots?

For a wearable robot to effectively assist with walking, it is crucial to provide the appropriate level of assistance at the appropriate timing for the wearer.

Q: What type of sensors are needed for the soft exosuits?

Soft and easily integrable sensors are required for the soft exosuits to monitor forces and movements.

Q: How do the sensors and monitoring information contribute to the assistance provided by the exosuits?

By utilizing the information from the sensors, such as forces and movements, the exosuits can trigger the application of actuation assistance at the right time.

Q: What progress has been made in terms of human-machine interaction?

Significant progress has been made in human-machine interaction, allowing the wearable robots to work in uneven terrain and avoid obstacles. The system is in sync with the wearer, providing a natural walking experience.

Q: Apart from portable robots, what other equipment is being developed in the lab?

In addition to portable robots, the lab is also developing lab-based equipment that enables rapid understanding of the biomechanics and physiological implications of using these machines.

Q: What is the significance of human-in-the-loop testing?

Human-in-the-loop testing allows for the rapid exploration of different design architectures and control strategies for the exosuits. It helps determine whether the development is moving in the right direction.

Takeaways

The development of soft exosuits and wearable robots shows great potential for various fields, including elderly care, the military, first responders, and athletes. The focus on mimicking the function of muscles and tendons, along with the integration of soft sensors, enables the provision of appropriate assistance at the right time during walking to improve mobility. The progress made in human-machine interaction allows for natural movements in uneven terrain, and ongoing research in lab-based equipment helps gain a deeper understanding of the biomechanics and physiological implications. The potential applications of this technology are vast and exciting.
