robo-one 12

hey I was looking some of the pics on robots-dreams of the bigger bots that some of these guys are building. They look pretty impressive. Does anyone one know what kind of servos they are using to move those big things around? They have to be pretty much fully custom right? Just curious to know a little about them, seems like they would use a lot of power.

You're right. They are really impressive, especially the ones that are done well. OmniZero is unbelievable. He almost captured first place in the technical demonstration phase of the competition on Saturday, but was aced out and got second place.

They do take a lot of power, and a lot of $$$. The power and cash required goes up very quickly as you scale up the size. And, when they fall down, they go down hard, so the design has to be much more rugged and durable.

Maeda (OmniZero) always uses JR servos but repackages them - sometimes in a very creative way. The Gadget Team from Korea uses Robotis Dynamixel servos, and Sugiura (Dynamizer) used Robotis as well for the 5 kg re-design. Some of the others use the high torque Kondo 4014/4013 servos, and there may have been some other servo manufacturer based designs as well - I'll have to go back and check my notes.

What sites do you go to to find up dates about robo-one related stuff? The only one I know of is robots-dreams. I was wondering if there were anymore. What kind of size and weight requirements are there on these bigger robots? I know that builders are being encouraged to increase size. It seems like 5kg is where most of them are now, but I was wondering how heavy they are going to end up being. Do you know how tall some of these bigger robots are? I am in the process of designing a humanoid, but it is going to be a little bigger then most of the ones that are in competition now. I'm working with pretty much no money so it takes me a while to get things that I need. I am also not using servos (yes I know it sounds pretty funny) so I have to develop a control system from scratch. I hope to have a prototype up and running by the end of the year.

A good place to start getting a feel for the height and weight is the ROBO-ONE database. It lists all the entries along with their height, weight, team names, sometimes links to the team websites, and what competions they entered and how they placed - if they did. It's on the honor system, and all the data entry is done by the competitors, so there are some omissions and errors, but by and large the data is pretty good.

thanks for the advice
