What is a walker?

[daliad100]

For degrees of freedom of a planar mechanism (flat) the Grübler formula:

DOF = 3(n - 1) - 2l1 -l2

Where n = number of bodies (number of links including sliders)
l1 = number of joints with 1 dof (pivot on its own and slider on its own count as one dof)
l2 = number of joints with 2 dof (pivot on a slider)

Should be easy enough to check if a 2d mechanism adheres to the rules.

Thanks
That's great give us some examples. so we can see it working say the Klann walker

From what I understand about the linkage, it has 5 bars and the background making for 6 bodies, 7 single DOF joints and no 2 DOF joints making for only 1 DOF total.

Hence not a walker by the rules.

I don't think anything that uses a continuously rotating crank as a direct input can have more than 1 DOF otherwise it will be very wobbly and collapse.

​If you guys need any more just say.

Big foot is this the best you can come up with??? As a fighting robot it's a sick joke!!!

I ask again Can anyone, anywhere show me a walker from the past, present or if possible the future, that qualifies under these rules, that has won any fight in any weight class, any were in the world! ever!!!
