ロボット触覚センサのトップランナー、 PaXiniのセンサをテストしてます。このコンパクトさでありながら、力が3次元的に分布で取れるのは驚きです。 放熱が難しいのかやや熱を持つ感じがありますが、ホールセンサ系にも関わらず磁石を近づけても値がブレない。 そして超絶安いんですよねこれ。。。

ちなみに型番はPX-6AX-GEN3です。 本体はアリエクで買えるしすぐ届きましたが、通信ユニットは若干値が張ります。 評価や試用はカジュアルにできますが、実際導入したことある人は居るのかな?

この前試したオープンソースのホールセンサ系の触覚センサも全然良かったが、磁石近づけたら普通に崩壊したので(映像には写ってないけど)このあたりは製品レベルの違いを感じるところ。

Great test video! Thanks for trying our sensors

Thank you for sharing this with us. Congratulations on such an impressive product! We'd love the opportunity to visit your office sometime.

Warm welcome! We have newly opened global appointments for showroom visits. We’d be thrilled to welcome you here!

Fascinating progress in tactile sensing! Compact, affordable, and reliable force perception will be a key enabler for more capable robots that can interact safely with the real world. 🤖🚀

how do you manage to get rid of interferences with an Hall sensor?

Good question! In general, Hall-based tactile sensors often use a differential / gradiometer configuration to cancel out uniform magnetic fields, and sometimes magnetic shielding as well. PaXini seems to handle external magnets surprisingly well in practice — the output stayed stable even when I brought a strong magnet close. I’m guessing they optimized the sensor layout and filtering quite carefully.Have you tried any Hall-type sensors that were particularly sensitive to interference?

Just seeing this, sorry. Oh nice to hear, thank you for the feedback. I do not have hands on experience with Hall sensors, so my knowledge on the topic is exclusively theoretical.

Wow I'm going to buy some units! 🤯

Great trial! I haven't try it, but how about sampling rate?

They said 1MHz internally and 1kHz output. If actually 1kHz output is available, it's fantastic!

Here is the spec

Thank you a lot! I will check it out.
