While I am not really that interested in Bipeds right now, I am a bit intrigued by some of the leg designs and how I might use them in ways not yet imagined by most. I got bored this moring so I thought I would take a shot at modeling a biped robot leg. The Scout looks interesting, so here is my first effort at modeling a biped leg.
The second servo from the top is backwards (shouldnāt really matter much though). The top servo also uses a C bracket and not a multipurpose, though you might be altering that part for use in your bot.
I switched the second servo from the top and removed the top servo from the bracket I had it in since it fits into the torso of the Scout as far as I can tell and it is the sixth DOF for the leg.
I am not planning to build a biped anytime soon. How could the top servo be in a āCā bracket, or any bracket actually? It fits into the torso.
I am just trying to model the leg of the Scout as perfectly as I can so I can get more practice with 3D CAD. I may have other uses for that leg design in the future.
The top servo gets a C bracket and a hinge while being joined to the torso. I do have a Scout standing on my desk. You might want to see the whole assembly guide for the detials: lynxmotion.com/images/html/build53a.htm
Granted, that bracket might not be necessary for motion, but itās part of the stock design. Hmā¦now you got me contemplating removing them so I can add some additional payload.
I thought there was a reason, just couldnāt see it at first glance. Iām assuming itās to prevent stresses on the screw and servo horn on the top servos. I can easily see how with plastic geared servos, or plastic horns, this might become a break site without them. Using better equipment would lessen this, but is still probably a bad idea. If I really need extra payload, I might remember to investigate this further though.
They are on the opposide end of the servo, so the ball bearing lines up with the axis of rotation of the servo. In the torso, the servos point down, and the hinges sit on top. Yea, the assembly guide has them upsidedown since itās much easier to work on it that way.
Not right away, but I am seriously considering it at some point in time. I have other projects that I want to do first, like build one of my hybrid robots. I am also designing a robot that will possibly use the Scout legs, but this will not be a biped. I promise it will be a unique design.
