Good progress this week. The first SLS printed Beta unit looks amazing!

Servo jigs are loaded and ready for some bulk setup. We're pushing to get the first round of Beta hands assembled and out the door.

Here is a much more detailed shot of an assembled thumb made from SLS printed components. The fit and action is definitely the smoothest we’ve seen so far in printed parts.

Should also note - these were printed locally here in Vancouver by @Shop3Dca on a Form Fuse

Morning testing. Range of motion test on all the joints. Moves a bit notchy because I’m stepping in degrees, but looks good overall!

A busy bench here again today. Kind of a cool shot to end the day though.

Hello from DexHand! Mounted up to the UR3 for the first time today. Still a few things to figure out, but this is an exciting step forward

Test sequence, with most of the guts tucked inside the hand. Moving onto thumb control next. There's 4 DOF's in the thumb so I need to figure that out.

Routed some basic bus bar boards to tidy up the wiring in the palm today. Worked out great!

First cobot forearm build is progressing well. This is designed to attach the DexHand to a UR3. Hoping to test it out next week!

Beautiful chaos. Building up a couple cobot hands this week.

Been a while since we’ve dropped a video of the DexHand. Here’s the result of some Saturday morning hacking with a crude initial calibration. Still surprised by how fast this thing moves!

Tap to open the video - crop is a bit weird.

Our dark overlord @iotdesignshop just open sourced an internal tool called Feetech-tuna. If you’ve ever used FD.exe to commission Feetech servos, you might want to have a look. iotdesignshop.com/2024/05/15…

Built up a finger set and finalized all the plastics for the first cobot forearm build. This one is going on a UR3 at the shop for some life cycle testing.

Sneak preview of the #cobot forearm for the DexHand. This unit has a flange adapter to fit on a UR3, but we're planning to make them for any arms that customers might want to test the hand with. What are people using our there these days for arms other than UR?

Not the most exciting motion path, but the USB control stream to and from the DexHand is working. I am testing a 50hz servo position update loop upstream and 10hz back down at the moment and it all seems healthy. Obviously, the servos don't update that fast, but was curious.

Click to open the full size video. The crop is a bit crappy.
