Very impressed with the work that you are doing, and enjoy watching the videos.
In the latest you had the issue of maintaining belt tension when the leg under a lot of force/weight... since the force direction is asymmetric (ie always in a particular direction) can you create a upper leg which deliberately flexes a little and creates more tension in the belt as it does.
This maybe could use a cam to push on the tensioner as the leg flexes. As a side effect it would create a little more leg springiness by using the belt elasticity.
