(BOM) bill of material about opencat-old HOT 10 CLOSED

Machine Learning & AI Additionally, there are new developments in image processing on the RaspPi using tech Intel has bought – Movideious. https://www.movidius.com/ RaspPi example: https://medium.com/deep-learning-turkey/a-brief-guide-to-intel-movidius-neural-compute-stick-with-raspberry-pi-3-f60bf7683d40 also this might be interesting, Intel Real Sense Depth Cameras https://www.mouser.co.uk/new/Intel/intel-realsense-camera-400/

may be Aiot chips like K210 low power consuming & low cost can work?

Thanks, this is an easier start for me.

My list on Hackster is a mixture of the mini kit and the full cat. I'll group the components for building the mini kit from scratch, and note their specific parameters and requirements. You may help to find the best online links for individual makers. I'll continue improving the kit for scale production and contact wholesale suppliers for larger orders.

I think it's better to manage the BOM in the code repository. I heard that Git is not efficient for Excel files. So I want to create a text file with formatting:
item , quantity , notes , example product link \n

Do you have better suggestions? I can work out the list during this weekend.

I'm currently buying some of the parts. And I have a question - is there any sort of tips how to distinguish the original servo MG92B from a fake?

from opencat-old.

@ikwic By luck? I did notice the variation in my separate small orders. Basically, the lower the price, the more chances you'll get fake ones. If I were to order the servos for my commercial kits, I'll contact the official manufacturer directly, order 1000+ units and ask for wholesale price.
You can start to order the parts now, but note that I won't be ready to release more instructions in the following two months. You may use the components to test separate functional modules like moving servos, reading sensor data, etc. They will help you understand my later codes for driving the robot.

@asmales For most of the parts, using PLA is fine. The position of screw holes won't change much. Shrinking will be a problem for one or two structures where the mechanisms require a very small tolerance. I'm specifying ABS only because I have tested the dimensions after costly failures. For printing with PLA, some magnification factors has to be experimented and determined.

PLA is fine however PET, PETG and TPU are more common for parts requiring strength and durability. A useful tip from the 3D printing community is to use threaded brass inserts when needing to screw into a plastic part. These are inserted using a soldering iron to heat the insert to place it by melting it into the body of the plastic. The brass will be durable and won’t strip steel screws. ABS is OK but warps and is relatively heavy compared to better plastics. There are dozens of filaments to try. I would get online and ask Tom Sanladerer for advice. Tom's YouTube channel is very educational and Tom is an engineer by training so understands the issues you face. https://youtu.be/CZX8eHC7fws Shows Tom testing many filaments including baked PLA for strength. Tom's filament tests are very thorough.

@peterhyphenhyphen Thanks for referring that resource! I will cite your note in later documentation on the instructions.

Have you guys considered about K210 as the Machine Learning & AI processor? it's just $2.99 for the chip -

my notes on K210 and relative things -

15fps+ for YOLO, can be overclock to about 1GHz for about 1TOPs -
