Hi all, this is my first time really posting here, but Ive been lurking here a while looking at all the great projects and finally am able to pursue robotics as a hobby. It is something I have always wanted to do. Anyway here is my first creation in progress. I call it Sampson and am creating it for a robot fighting competition I want to start. He will be the first of two, after which I will create a video for you guys to see
Yes I had originally intended to make the arms come out using firgelli L12 linear actuators. But after some advice from experienced builders I have decided to go with 5990, although I would still like to mount the servo on the torso and control that pivot with control rods cause I think it would be cool and it feels like it would allow the servo to get more leverage. I am going to do mech wars. But not the on over at trossen. I have been wanting to start a tournament like that for years and I think his idea is excellent and even would like to participate with a different machine. But I will be doing a different tournament with very different rules and scoring system. And because of that my tournament is not limited to walkers only. I am building a second machine as well after which I will post a video of the battle between those 2 and it will explain the rules and what not. I am hoping you guys will love it. It will be alot of fun…
5990s… The stronger the better, that’s for sure. Weight is everyone’s worst enemy when it comes to jointed assemblies. I love the aluminum pipes you used to connect the torso to the rotating base. Great job!
Ok, new update. I just received my four 5990 servos and man those things are strong. After messing around with some arm and spine configurations, I refined my original design. I wanted to get a very aggressive look as well as to have some serious muscle to back it up for robotic combat. I am going to order four more servos for the opposite side and that should complete the overall body. I also mounted a temporary cannon in the front but will replace that with a good automatic cannon. Hope you guys like
I totally agree with Mike! Great looking bit! But I’m a little bit concerned about the mounting of the upper body. It looks like the upper body has got some serious weight which is all carried on a single SES L bracket. How does that part hold under the amount of weight? It is solid or does it bounce a little bit? Are you planning to replace that part with something more solid or is it fine?
Thanks guys for the feedback, Xan I agree with you about that L bracket. At the moment it was all I had available, but it has been a concern of mine. It does seem to be holding up pretty well although when I activate the servos I do get some bounce and at the moment its only the one arm, I still need to add the second arm. The other thing is that your right about the weight, it is heavy and while those 5990’s are incredibly powerful and great they are very heavy. I am going to revisit that connection once I order some more parts. I waiting for the funds to order my next and hopefully final wave of parts to complete this machine. Then it will be on to the programming. Then I want to make tons of videos of this thing in action. I am dying to build like a small mock city and let this beast loose.
Yeah I thought about that, but I was trying to figure out how to connect them both to each other and to the hex piece since at the moment I cant figure out how to screw them to each other from the inside, any thoughts?
Take a cap screw and run it from the inside of the hex part to the out side and in to the AHC-01, then you can use a nut to secure it. I’m not sure if the hex part is threaded or not. If the hex part is threaded, it will not matter becuse the bolt will act as a stud sticking out for the ABC-01 to attach to. If the ABC-01 is threaded also, then the cap screw will need to run through both parts at the same time. I would use an allen wrench
it’ll be great for mechwars
