CAN BUS Control Score 7773
Challenge. Go big or go home.
I'm looking into the CAN actuators used on the Cheetah mini. They are not poorly priced ($300) and offer 150 pound/inch of torque @ 24v. They are brush less, geared and have their own built in drivers, smooth motion and quiet operation. I have an up coming project and would like to control these with EZ Builder. There are arduino shields that support CAN and there is even a pre-written sketch to send data to a CAN actuator. The actuator protocol is somewhat like Dynamixels, in that you can change ID, monitor temperature, control speed, direction and position.
What say you? I'd like to see support added for more industrial actuators like this one, and Servos like ClearPath . Inspiration came from this guy (who cracks me up) and managed to pull this off very quickly using a few of the tools below. Hardware starts at 5:40.

Yes, affordability is important but so is availability... No point creating a control for actuators that are difficult to find and/or buy.... I also would definitely be interested in these type of actuators....
That's your mission, if you choose to accept it - determine what actuators you wish to use so they can be supported.
I am completely with you guys.
Lets research...sit down, do our homework and also whoever thinks that a product is good enough to be worth the investment, will need to buy it anyways for further testing! I mean, for an arm that kinda works, you'd need at least four of them!
I just wanted to share what I found, I did not mean to imply that @DJSures will have to make a thousand skill controls for all those different actuators!!
The company I originally linked to in this thread with the robot arm must have broken TOS with Kickstarter as they have been taken down. They are in Beijing.
I believe the video I just posted is using those actuators. But how to know if they will be publicly available?! I also like the size.
Aliexpress has a robot parts section. Maybe we start there. I plan on covering this topic on a future episode on YouTube. If for anything the importance of compliance in larger robots.
But price vs strength is the ticket.

They are US $359.00 at Aliexpress ...
edit I thought these were the ones that you meant when you talked about the original post...ups!!
Hey is also reviewing these ones...they come in two flavors!
US $448.00 https://www.aliexpress.com/item/10000018030781.html
US $379.00 https://www.aliexpress.com/item/10000004036730.html
INNFOS is no longer available on Kickstarter, but I guess they will be selling the product elsewhere soon?

I’m curious about the Kickstarter. Maybe an investor stepped in to fund them completely.
I did see those other actuators reviewed on skytenifics channel. They are very pricey and physically bigger than Innfos, but I bet considerably stronger.
