Enhancing Balance and Posture in Material Handling Tasks with a Wearable Robotic Tail
Enhancing Balance and Posture in Material Handling Tasks with a Wearable Robotic Tail
This research paper introduces a wearable robotic tail designed to improve balance and reduce musculoskeletal strain during heavy lifting tasks. Through experiments with ten participants performing shelf loading and unloading, the active robotic tail demonstrated significant improvements over passive and no-tail conditions, including a greater than 20 mm reduction in centre of pressure peak displacement, a 4.3 degree reduction in trunk motion, and over 9% and 20% reductions in erector spinae and gastrocnemius muscle activity, respectively. While the passive tail offered some benefits, the active tail provided additional augmentation, particularly in reducing lower back muscle activation. The study concludes that wearable robotic tails can effectively enhance balance during material handling tasks.
The study reports kinematic and muscle activation data from a controlled experiment with ten participants, but does not claim general deployment readiness or long-term safety validation beyond the specific material handling task conditions.

Inspired by animals using tails for balance, we developed a wearable robotic tail as a dynamic counterbalance. Ten participants performed an imitated shelf loading/unloading task across three conditions: active tail, passive tail, and no tail. Kinema
