I guarantee it will cost more than $100, but for help planning I suggest homebuiltstabilizers.com I have tons of research on these puppies, and have built two of my own. If you want some help, or suggestions, let me know! By the way, electric controls are good, but manual is way better if you can get good gearing work done. Electric tends to be noisy, and expensive for the motors. If you do go with electric, you're looking at spending $2000 on just the motors if you want them to be silent.
Good advice Shane. I will check the web site. I already have the motors though, (three) and yes they did cost (somebody) over $3000. I got them off a weed-eater robot a guy made around 5 years ago; because he was a genius, was really, really old and didn't want to weed-eat his yard. He just wanted to just sit with a radio control and a lemonade and let a robot weed-eat his yard. So, he spent over $4000 on creating a one-of-a-kind robot. He machined the gears and stuff himself and they are completely silent. They even have their own built-in sealed oil baths for the gears... which I may or may not use. He ran it once and then died of old age... and I got it from his sister. He was brilliant and had worked on the Manhattan project back in WWII.
I will take your advice and look into both methods of control though. I will keep receipts... If I make it for less than $100, I want you to treat me to a double-double burger dinner at In-N-Out, 'K? If it costs more, I'll treat you. Never underestimate a scrounge like me. :kali::kali:
Did you make your cranes with triangular modules or did you make them with square modules? I have plans for both.
