I can command the robot to move to the cursor state, at which point both Sim and Live attempt to do so. if Live is connected to the physical machine (the serial connection is open) then the real machine will move. Because Sim is using the same path planner and timing as Live, the Sim and Live will move as one. This is a cheap way to detect unexpected interference - variation greater than some epsilon is sign that the real machine is colliding with something. It also gives me a way to get accurate time prediction on every recording.
Students in Montreal purchased our kit and used the open source instructions to build a Sixi robot for their autonomous rover competition. This is the latest in-progress shot I received. Nice nice nice!If you're interested in building your own, check out the Sixi robot open source BOM, STLs, and more.
Sixi 2, An Open Source 3D Printable 6 Axis Robot Arm

There is a growing number of open source robot arms, which is super. I only build one because I can't get one at an affordable price. So if you're making an arm, please let me add Robot Overlord support and together I hope we can achieve greater things.
Nice Project! But I wonder if you are giving a way much strength and stiffness by using open cross section profiles (H and C) for the arm. In my experience constructions made out of plywood and with finger joints are much stiffer if they are closed all around. Holes in the walls are often not a big problem but missing walls weaken the parts notably - especially wrt (lateral) torsion.It is a bit difficult to judge just from the pictures but it also seems that the different axis of the arm have different strengths - limiting the capabilities to the weak ones. Especially the NEMA17 motor for the first axis looks much weaker than the linear actuators for axis two and three, given that is also has to deal with the full length of the arm as a leaver.
Parisian large scale 3D printing firm XtreeE for instance, received funding from investors TTWiiN Investment Partners in June 2019, to develop its large six-axis 3D printing robot. The bionic arm is capable of printing concrete and clay with high precision, while the company also uses the bot to assist clients with collaborative design, and large-scale prototype manufacturing.
For anyone looking for a capable robotic arm for automation of an industrial process, education, or just a giant helping hand for a really big soldering project, most options available can easily break the bank. [Mads Hobye] and the rest of the folks at FabLab RUC have tackled this problem, and have come up with a very capable, inexpensive, and open-source industrial arm robot that can easily be made by anyone.
If the robots take all the jobs, only the robot owners will have power.In order to ensure democracy, the robots must be owned by the people.Open source robots are a must.The most important robot I can make is a helping hand.I aim to make Marginally Clever Robots, Ltd. into the Prusa of robot arms.We will make an arm so good it can build its siblings (aka 'eat your own dog food').
There are magnetic on-axis sensors for feedback. The robot always knows where it is without having to home to a limit switch. It might also one day be possible to detect collisions for human-safe collaborative work.
