Yeah, when I was 12! I followed a guidebook, used a breadboard (mom wouldn't let me use the solder), and connected it to my x8086. It was-- Oh, you mean ironically. Yeah, I built a robot that does--among many other things--your mom.
So you want a robot waiter to save you the trouble of going into the kitchen...but how is it going to get the food to start with? What you need is a robot chef.
If you're saying seven arms, and one of them is a knife - i'm not made of robotic arms. I may have to crowdfund this Anyone here built a crowdfunding page?
Of course! The solution was so obvious, we could not see it. Punk, build a robot building robot. You’re welcome.
Not a real robot, but our village has an annual Scarecrow Festival where most households make and build a scarecrow to display. I always let my kids decide the theme, and I will make something. A couple of years ago they asked for a robot, so I made this below. It was about six feet tall and was made almost exclusively out of wood, even the rifle. Note the Boba Fett inspired range finder on the head lol. Other inspirations came from 2000ADs "ABC Warriors", the Star Wars Battle Droids and the Terminator. The leg pose is because I was going to have it holding the rifle similar to how Vasquez holds her gun in Aliens, but it didn't quite work out. The last picture was the entry from the year before that, when they asked for a horror theme scarecrow.
my friend coaches some high school robot fight club team. It's exciting stuff. Now is the ideal time to steal the equipment you need from a high school or junior high school. Pandemic is a golden age of opportunity that won't last forever you know.
I mainly make scale foamboard planes, depending on the size you would need a huge servo to operate the limbs and if you are going for fully autonomous then motion sensors, gps, fpv cam, head tracking cam etc. I have build 2 autonomous drones that will aid in search and rescue that operates in a grid pattern. (Took me 2 months and 2 years of pocket money to code/build from scratch). Don’t know if that counts as a robot. But yes. Money is needed, lots , and also a good workshop, solder, and an high IQ.
a friend of mine volunteer coaches the robotics club/competition team at his daughter's high school. I think for competition, the robot waiter's defined tasks need to be a little bit more specific.
