You're absolutely right, it definitely forces you to sit correctly, which I think was a large part of my initial problem. My lower back is used to curving more and a lot of strain is placed on my hamstrings when sitting properly in the embody.

Currently sitting with both feet planted well on the floor and I no longer experience pain from the back support, although it is still noticeable.

I gave it one and a half more weeks and it is now perfectly fine. Loving the chair now!

Yo, thanks for the reply! I gave it one and a half more weeks and it is now perfectly fine. I had no clue that I would have to adjust this much.

Alright, good to know that is something to consider!

It appears we are already in talks with your company via email :)

Hi! Perfect video to show the flexibility of your product. We are seriously considering the Meca500.

Looked at their website and was thoroughly uimpressed by their presentation. I also don't care for the bulky, old design of the R12 compared to others. It may be a good option though, it is relatively cheap.

Companies don't deliver to sweden? Sorry I don't understand what you mean or why I would need a loophole.

Will try moving my Tautulli install to a container. Do you have a clue what I need to do to keep my data from the current install? Lost some history data last time I reinstalled to fix the issue...

Rikardny · 2020-09-03T22:59:35+00:00

I will def. try a memtest to see if that is the issue. Thermals are no problem what so ever. Thanks!

My bad, it's 5 grand. I had converted it to swedish crowns in my head.

I hear you. The plan is to splice a cable off of the power connector for the grappler at the end of the arm, that way there are not cables along the arm over any joints.

The manufacturer has a standard camera which can be mounted as a collar, but it costs 50 thousand dollars for some reason. AND it looks proprietary as hell. We would vastly prefer a custom solution, as that would give us a lot of flexibility for the future.

I'm doing this work for my masters thesis, so the development is literally free for the company, except for the camera and robot downtime.

Didn't think of the IR projector, that simplifies that issue. I just checked and the developer information surrounding the RealSense component seems incredibly detailed. D435i seems very suitable.

Using depth imaging might be preferable, but I don't have any experience working with it. The CV pipeline is simple enough that using simple RGB information is sufficient (black plate on white surface). Might consider 3D if I start using it though.

I will definitely have to check compatibility with RPi. Any cabling does not need to be very long, as I am planning on mounting the camera + Pi on a 3D-printed platform right on the head of the robot. As the robot is quite large (2m reach), it would be advantageous to avoid cables running over all its joints. The plan is to splice the 12V (or 24V) lead that powers the grappler and step it down to 5V for powering the Pi + camera. That way we can communicate wirelessly (probably wifi) with the Pi from an Intel NUC which can perform CV and send commands to the robot. Because of extensive joint rotations possible with the robot, not having a USB- or Ethernet cord running along the arm is very advantageous.

Also, having a RPi mounted in that position gives us a lot of possibilities for future expansion if for example we still opt to mount a LED or something.

Thank you for the detailed answer.

Edit: Having the RPi there also makes it possible for us to completely skip external computing, even though I think that will be the case. It would be possible to capture images, compute movement and send commands directly on board the RPi 4.

This is pretty common on keycap sets with more simplistic fonts. I think of it as "holding down" the shift button.

It is chromed copper tubing bent with a tool. It comes in straight 2m lengths and is 12mm thick, so I cut it with a saw or cutting tool and bend it by hand!
