openDog V3 is mostly mechanically assembled! It took a while to make things fit with some retolerancing and reprinting as I went, but it looks good now. Video comes up for Patrons soon!

This is looking really exciting James - can't wait!

Eric lamb

I am excited to see the results. Will you be able to use the full 56v on the Odrives?

Doug Cooper

really excited to see this coming together. Will you be using force sensor feedback to modulate motor torque on this version? If you watch the Boston Dynamics dog the feet seem to settle on the ground, not hit it.

I may go to 48v, which will be 6 cell lipos, but full charged it will be 50v. The capacitors are rated at 56v, so that is absolute max.

Yes I want to try force driven joints with this one. I have a few ideas about that once it's up and running.

I've just responded to a Patreon update from the creators behind Project Binky...8 years in the making and nearing its completion. Nice that it was followed almost immediately by this post. openDog is the opposite: part of why I'm enjoying the series is that it _won't_ ever be finished. There'll only ever be its most recent iteration.

Well I hope this hardware iteration lasts a while, it should open up a lot of possibilities all being well.

This is a nice step forward! But, How do you ever find enough time for so much printing? Also, which 3d printer are you using and do you find it accurate and reliable?

I have around 9 printers. Lulzbot have supported my for a number of years so I have 6 Lulzbot Workhorses plus some other models.

Thomas Messerschmidt

9? Wow! You must have an entire room dedicated to printing! I guess by now you get what you want from your printers without a lot of reprints. You never cease to amaze me.

I have just put them in one room on benches and things now so they are organised. Having so many printers is the only way I can get through the content production week on week.
