Hello guys, this is Simon.

@suren_at What was the main chip? We just made a teensy based breakout board

@dolylupec @wuji_global @TheHumanoidHub @XRoboHub I thought worm gears aren’t back-drivable. We have the first version of the Wuji hand, and those can’t be back-driven. I’m curious what they modified to make it back-drivable

@liminalsunset_ @boxcardavid Recently it’s about firmware, sat up the can id through their software, and after a few on and off power cycle while doing experiments on our robot, some actuators got disconnected, later they found that the can ID get reset to 0 and all things appears to went back to default set

The first version of our custom motor controller board is here. Let’s see how far we can take it! 🚀

@cixliv 😅

1st version will probably stick to can, later would like to try ethercat, anyone familiar with the communication protocol?

@CHENYAO981123 Hi Chen, we are considering to buy some my actuators, may I have you WeChat? Thanks 🙏🏻

@Sentdex RL with reference trajectory, probably similar to beyond mimic paper

@observie Hi David, is it a Pic chip? Also were you able to find Xt30 2+2 in the US, it looks like it’s only available through Chinese vender like jlcpc.

@Manh_Ti3012 I am curious how you trigger your adc reading to ensure low side fet is on, pwn interrupt? do you use pin that can do triple simultaneous mode? Is the reading for the 3 add up to zero? Also beautiful board :)

@cixliv On one end, we know safety is crucial; on the other end, making a robot completely safe before deploying it may give away the market to competitors on the other side of the world who are already deploying large numbers of robots to their customers.

@GoingBallistic5 @observie @KWRoboticsAI I talked to the people who went to IROS, and he said they use thick steel cable for the ankle roll.

@gan_chuang Thought they will go all out on robotics, didn’t they just recently hire Prof Sangbae Kim 😲

@ORHEX0 Found Berkeley humanoid lite use the exact ESC, you can try to use their code https://t.co/ZV2sdrmnLu

@KyleMorgenstein Whether you like it or not, your foe from authoritarian regimes will always find someone to do it, and they will spare no recourse.
