I just love robots, and I’ve purchased a few, but I just never had the time to play around with trying to build my own so I’m a bit naive of what is state of the art and how quickly we can expect it to advance. Maybe when my son is a bit older I will get to build some with him. I have a robot vacuum which actually does an Ok job on the first floor despite the software being extremely naive. I have a robot lawnmower which, after laying the guide wire, does an incredible job on a fairly complex half acre and was worth every penny, and also accomplishes its task with surprising naïveté. So far the success of robots seems to be in finding ways to reduce a seemingly complex task into a random walk. I dream of robots doing all sorts of helpful things. Big robots that help me move stuff around the house (and maybe even up the stairs?). Little robots that can unclog a drain. Ridiculous gyroscoping telescoping robots that scoot around the kitchen and put away the dishes from the dishwasher in perfect stacks way up on the highest shelf. Specs say Spot weighs 70lbs and can hold 30lbs. 2:1 seems actually... not bad. What’s the chance the tech evolves to 1:1 in 10 years? Is weight to payload ratio even a reasonable metric? I feel like the three big things are 1) degrees of freedom, 2) torque, 3) finesse. I don’t really have a good grasp of how much the problem is breaking down at either the software or the hardware level where I’ve never seen a robot that could really do all 3, even if it was a totally preprogrammed hard-coded action.
