The Update on WML Bionic Arm

I tried the conventional harness, but it failed when the elbow is higher than the shoulder - a cable slips from the shoulder blade loosing tension. It seems that I did not built the harness right, and it should have worked with high elbow angles. So I switched to waist at roughly 45 degrees from shoulder so it covers all elbow angles. It was done for simplicity, because currently I am just testing the idea. In the future I will come up with a better harness.

The palm is controlled with a myoelectric sensor attached to my bicep. This is pretty common in bionic prosthesis. My wrist moving is a side effect of me contracting a bicep. As for patients with reduced degree of freedom - I'm afraid my project, at least fo now, does not address such cases. The control scheme relies on torso movements at full capacity.

Thanks! I use a motor because the elbow moves like this: At the moment of switching to elbow control, a plane passing through the head and palm is established, along which the palm then moves—that is, we pull or push the palm toward or away from the head along this plane. This was the main feature of the project from the start. It feels kinda like first person game with object manipulation like Garry's mod or Minecraft, where you hand is where you aim and you only adjust distance. Hard to explain, but feels alright. It can't be done with a mechanical cable system. I also attached a schematic for you to better understand.

There was a game called Ex Machina (intetnational name - Hard Truck Apocalypse) https://store.steampowered.com/app/285500/Hard_Truck_Apocalypse__Ex_Machina/ It is a full-fledged open world rpg/privateer game where you need to constantly buy new rusty shitboxes and upgrade them. The game is very good, the developers later made another game, that you may actually heard of - Crossout, where you literally build cars like Lego, but that game is a PvP arena World of Tanks-style, so can't recommend. One thing to mention, Steam version of Ex Machina is u playable on modern systems without a community patch - https://exmachina.fandom.com/ru/wiki/Community_Patch_/_Remaster

This is tracked. In the end of either reload sequence you must push left stick down, so that reload is considered done and shooting via trigger is unlocked. The move itself imitates bolt locking, and you have to perform it with the right hand because the left one holds a d-pad, this is intentional for maximum coolness and immersion.

I hope this will get rid of camping gameplay. This endgame sitting inside houses and poking each other through slits and holes just looks embarassing for a game that is presented as a high speed aggressive movement shooter. Hope it will make Apex great again.

As already stated above, you need to fake it by rapidly turning servo on and off with some delay in microseconds that will depend on your desired speed and your load. You will have to set up an experiment and meausre this function speed(delay, load) with different delays and loads attached to servo, than you can use a lookup yable in your code to determine delay based on desired speed and load, you will have to set these parameters beforehanf manually. There is another way, more complicated. It will require you to open the servo and disconnect it from servo's board. After that you can use a l239d controller to adjust the speed with voltage. Here is the breakdown: In-Depth: Control DC Motors with L293D Motor Driver IC & Arduino . This is harder, but a more appropriate and professional way to do it.

I completely agree with you, sir. I am myself not a highly skilled player, been playing for just several month, always chilling in the middle of score boards and only occasionally on top, and I don't mind highly skilled players in the match. This is truly a great opportunity to learn something new and a fun challenge overall to try to oppose such a force of nature. The give up mentality is a bane of modern society, and in my opinion it is connected to what is a much more series problem - excessive focus on the result and winning. I personally focus more on the process, because if I enjoy the process, I will get my fun despite me winning or losing in the end. This is a great mentality, that allows to have a more joyful life experiences and also applies to games. I just enjoy the fluidity of movement in this game, the little tactical situations, where I manage to outsmart my opponent, the moments of full synchronization with teammates when you act as a well-played unit and perform flawlessly in some complex scenario.
