Astra The Ai Dog

Created by @scattercat-123

Astra: The AI Quadruped dog

What is this?

  • A dog which acts as a companion robot dog.
  • Uses Actuators with planetary gearbox and multiple sensor for advanced AI!
  • Using jetson nano orin super(raspberry pi using for testing)!!!

Day 1: Research and starting fusion

I have already researched enough­. imma start Okay im using carbon fiber rods for the leg! And for the foot im using a silicon molded ball thing :suspect:

A somewhat completed foot 🦶

Day 2: I dint show you something b4

I actually had started designing 2 ACTUATORS. One was using a camera motor - i forgot whats that called. but that only had 2.5kg/cm which i had observed after an entire day. Faliure photo :( - image I was going to make like a planetary gearbox but nvm.. Then i thought i would use the eaglepower 90kv motor just like Aaed Musa and then i was gonna build a planetary gearbox. i was almost done but later i realised that it would become too expensive after me buying odrive s1's. So i went on alibaba and the chepaest thing which i found which has a encoder and driver built into it was this motor THE GIM6010-8!!!!!!!!!!!!!!!!!!!!!! This was the perfect motor because it had a stall torque of 11n.m and the motor was tested by someone over here Also this has a driver and it has like planetary gaerbox in it. so this was perfect. and it was kinda cheap. bruh - 70$ 💸 Can someone help me rob a bank 💰.. jkjk dont call 911 Yeah, wasted i gues 3-4 days on deciding a motor.

Day 3-5: Designed something :)

image If you can see these are gt2 belts. so like the motor will stay on the hip but drive the knee axis. this is actually usefull because i researh showed that the battery would drain faster if the motor was near the knee because of incraesed weight 🤓. so yeah

Day 5-10: did very little stuff

Im very distracted here is some final thingies. for all axis - knee, hip, abduction joint( aka moves your lige side to side. image image image image So basically the leg was done!

Day 10: Dont ask me why is this so complex..

Yeah i just realized it would be hard to 3d print and assemble some parts. so fixed mny issues!

Day 11-13: Final Full dog design.

Today I designed my almost complete dog. image

I also finished my overly expensive BOM Right now i am not adding sensor mounts and all to my dog since i will test my ai stuff and then add sensors and all for autmoated dog exploration.

I am not sure if it looks good. But remember to star my repo

Day 11: Final stuff

Some final adjustments, submitted in highway pitstop channel.
