Sit Wekit: ankle exoskeleton fills market gap

Liu Chunhua, chair professor at the School of Energy and Environment, City University of Hong Kong, came up with the idea in early last year to develop a lightweight exoskeleton that assists the ankle alone, filling a gap in the market. He pointed out that mechanical exoskeletons are bulky and expensive, and the vast majority on the market target the waist, hips and knees, with very few targeting the ankle. Assisting only one joint can significantly lower the price, making commercialisation relatively easier.
