This 3d printer prototype has five axes. The bed spins and slides, the arm holding the nozzle moves up and down in and out, and tilts. Here, the translational degrees of freedom (XYZ) are held constant while the angular ones are allowed to change, essentially orbiting a point.

A miniature 6-axis robotic arm prototype was tested to evaluate its 6-DOF (Degrees of Freedom) performance. Colored markers attached to the end effector represent the X, Y, and Z axes of its reference frame, providing a clear visualization of the motion. The arm demonstrated relatively smooth movement for an early-stage prototype, though some wobbling in the reference frame was observed during rotations. These variations are likely due to part tolerances and assembly imperfections. Video credits: Oleksandr Stepanenko #robot #robotics #engineering #automation #robotarm #roboticarm #actuator

"Pokrovsk has essentially fallen... there are some mopping-up operations going on, but the game of Pokrovsk is already over, and Kupyansk is almost there." Mark Sleboda explains that while the West has presented the war as a "stalemate" for months, Russia has been "attriting away the manpower and defenses, not just in one location, but in at least five big locations and many small ones all along the front line, and now all of those defenses are crumbling at more or less the same time."

Who wins out of feminism? Financial elites and degenerate men. Not women. On the contrary, they are the ones footing the bill. And what does it say about Western man that he has laid down and allowed his woman to be turned into a mere worker in the name of “liberation”?

In a sinister attempt to wear down resistance to compulsory veiling in the wake of the Woman Life Freedom uprising, Iran’s authorities are terrorizing women and girls by subjecting them to constant surveillance and policing. Women's rights are human rights. Always.

Labour are letting out thousands of rapists, sexual offenders, and grooming offenders out early. This is a choice, and a choice the Government are trying to cover-up. 🔵 Dr Kieran Mullan MP 🇬🇧 🇺🇦 and the Conservatives are rightfully holding the Government to account on this travesty

These are the mothers, sisters fathers and brothers of protesters who have been killed and executed in Iran. They held up photos of their loved ones and called out their names, refusing to let the Islamic Republic erase their memory through threats and intimidation. They say, they never give up and they cannot be silenced. We are all one family, united in carrying forward the path that Iran's heroes began. A path that ends in light and freedom.

The Iranian people are dying for their freedom. They are protesting against a brutal and despotic regime that has been in place for nearly five decades. Young people are being killed by this barbaric regime for fighting for freedom. The UK government needs to act now and back the people of Iran.

The supporters of peace are gathering. The winds of change are sweeping through Europe. In 1956, Budapest was the capital of freedom. In 2025, it is the capital of peace. Freedom and peace will prevail here, despite Brussels’ will. 🇭🇺

I THINK I KNOW HOW WE GET OUT OF HERE The sequence goes like this. Now, kick out ninety degrees to the right. Back two meters. And then to the left. And pivot two hundred and ten degrees to the left. And step out.

Democrats are the party of real freedom — and the @ErieDems prove that every single day. Good to be back in Erie to keep defending our fundamental freedoms and winning up and down the ballot.

A turning point in British-Palestinian relations, and a milestone in the Palestinian people’s long journey to freedom and self-determination. The solidarity of the British people has helped us reach this point and will be critical on the long road ahead.

The Iranian people are dying for their freedom. They are protesting against a brutal and despotic regime that has oppressed its people for nearly five decades. The Iranian regime is a hostile state and a threat to the UK. Words and statements from the government are not enough. The UK Government needs to act now and back the people of Iran.

We held the Crown Jewels, the man to change our trajectory, and we got rid of him. Sacking him will go down as the worst decision in our club’s history, every rival fan agrees, the only ones that don’t are the insecure Tottenham fans. Ange Postecoglou, forgive us and return.
