Excellent video, would love to see more like this and maybe a robot with a boom arm for close-up inspections at various heights/from standoff distanced, and with the ability to collect samples. Great work!
I am looking to use such suspension, 3 wheels on a rockers bogie layout, to replace the single front wheels of an off-road skate. Imagine the wheels spacing minimized and the wheels and tires lightweight as the weight and pressure will be divided and smoothened out. I figure using 3 rockered wheels, they need to be only 1/4 or less as strong as a single (front) wheel in a skate application. When an obstacle (say a 3cm branche) is encountered by three in-line 12cm wheels on such rockers, the whole weight of the skater is NOT transferred to the front most one. As it hits the obstacle, the 2nd and 3rd wheel will equally be pressed onto the ground. The rear wheel (behind the foot) is never as unweigthed as with a single front wheels. Each wheel when it rolls over the 3cm branche will only raise the front frame pivot by 1cm. Well, they are pneumatic so more like 5mm each time. A single wheel would have been sturdier and make the skate lose a lot of momentum and raise the front of the frame by like 2cm or more.
In most of these Rocker Bogie simulations it's never apparent that the gearing is needed, until you try to build your own and find that it would require enough weight at the bottom of the carriage to keep it from spinning itself around.
