This is not open source. The license has a non-commercial clause in it [0].

I'm consistently impressed by Seeed Studio's support for various levels of DIY in their products. I realize that many of the products are not totally original, but what I find interesting and original about the company is their interest in diy-accessibility and partnering with companies like Trmnl [0]. It's somewhere in between Raspberry Co, Adafruit, Pimoroni, and the like.

How does it compare to LeRobot SO101 https://huggingface.co/docs/lerobot/so101 ?
[−] michaelt 28d ago
The LeRobot / SO-ARM101 uses $9 motors [1] has 5 degrees of freedom and is available with all parts for $300 [2] fully assembled. They don't quote a payload, reach, speed or repeatability. Their target market is people who want to play around with things like imitation learning outside of simulation at the lowest possible price, and who don't care about payload, reach, speed or repeatability.

The reBot Arm B601 uses $150 motors [3] has 6 degrees of freedom and a kit with all parts is $1200 [4] not assembled. They claim a 1.5kg payload, 650mm reach, and 0.2mm repeatability - numbers that are good for the price, if true (take that 0.2mm with a pinch of salt). It has no brakes, so don't lift anything you're not willing to drop. Obviously it doesn't compare to a $40,000 industrial arm, but for the price you wouldn't expect it to.

Perfect clarification, much appreciated!

This is higher end arm, priced about 5x. I.e. they are not comparable.

I didn't know Unicode had a robotic arm in its charset.

What's the precision/rigidity/strength/repeatability like?

Wouldn't you need the axis 4 to be in line with axis 6 for it to have 6DoF?

If you want something more industrial Chinese arms that ape UR are 10-20k.

Can you make your GitHub at least a little bit not pure LLM. All those emojis cause me to instantly nope out. At least make me think you tried.
