    Wife complained about my workplace took up too much space. So I came up with this solution. Happy how it turned out 🙃

    I rarely share photos of myself. But here I am and my quadruped project [K3lso]. We're getting closer, no one is more excited than me! 

    Thanks 
    @UPbridge_gap
     & #Cubemars for the support, 
    @NVIDIAEmbedded for the cool shirt!

  • 10kg payload

    Robin Fröjd05/16/2021 at 22:12 1 comment

    so tonight I have been playing around with payload testing. Mostly to get some more knowledge and data of consumption and  to learn more about the robot capabilities. I am also interested to check this because my plan is to have an arm mounted on top which also comes in at around 8kg. 

    the UP Xtreme is included in the consumption data and have an estimated 0.6A consumption on average. The robot itself is aproximately 17kg net weight.

    Voltage is configured at 36v. 

    Payload 3kg = 1.67A 

    6kg = 1.91A 

    10kg = 2.35A (video)

    Front cameras and right side camera testing outside! as one can see the right side camera overlap with front cameras at around 2m from the robot. Giving the robot a very small blindspot. #k3lso #quad #quadruped #robotics #UPXtreme #ROS #Ubuntu #MIT #realsense #intel #d435 #d455 https://t.co/Eiv1QTE5X

  • Cameras!

    Robin Fröjd05/06/2021 at 20:30 0 comments

    So I got a few more toys!

    First test bracket for mounting the front cameras. I need to confirm my math on the angles and the combined FOV overlap!

Hi, could you give some details around the control system for the motors?

I believe the AK10_9 have their own control board so I don't understand the use of the moteus control board

Is this puppy ready for sale? I like the way he looks, but I don't know what his function is. Can it be compared with Boston?

What a pity! Many of my friends are interested in four-legged robots, but they just don't want to make one themselves, so I'd like to ask if you have any plans to sell it.so I want to ask if you have any plans to sell it. And I have a question, which way is your robot controlled, and how is the control effect?

This is awesome. Do you plan any AI models to use for navigation. What chip do you use for the "brain" part?

Great project. Could you tell me how do you want to manufacture the cover of the robot. It will not be bent sheet metal, am I right?

Do you have access to all this stuff at work or do you know any reasonable producer here in sweden? I've found that all plastic producer wants insane prices for the most simple parts, got a quote on 85tkr the last day for just one mold.

At the moment only for fun :) But I guess it will be open source in the end. ;) Thanks!
