Joel Robert Justiawan 🔴 What Is Islam? ⚠️ 🔴 Islam is not just another religion. 🔵 It is the same message preached by Moses, Jesus and Abraham. 🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. 🔵 It reminds us that since God created us, no one should be worshipped except God alone. 🔴 It also teaches that God is nothing like a human being or like anything that we can imagine. 🌍 The concept of God is summarized in the Quran as: 📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)[4] 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.

[@ulforcemegamon3094]

Well , i think is a quite a good trade-off considering the amount of torque it amplifies , since it seems that while it requires more maintenance , you don't have to use an servo with 6 times the torque since high torque servos are extremely expensive , so this is a light and cheaper way to increase the torque at the cost of requiring more maintenance

@Ginger Ginger Nah, they're not... most patent holders will license the technology for you as long as you pay a fee, and patents expire after a few years and can't be renewed. Oh, and patents are public, so anyone can look at the patent, get inspired, and create a new technology based on it... the point of a patent is to gain rights to the intellectual property for a few years, in exchange for sharing it to the world. Short term, patents stifle innovation, but long term (AKA longer than 7-10 years), patents really enhance innovation.

[@aserta]

Bravo, that is by far one of the most out of the box articulations i have seen. I will go as far as to say that this beats NASA's current space worthy prototype in terms of functionality and weight saving (which is a critical factor for them). IF it were my project, space would be pitch for this.

[@maxk4324]

Specifically which NASA technology are you comparing to? Because I can tell you that this design is substantially too heavy to be cost effective for space applications (ie not on any celestial body). For example (although NASA didn't design this, it's a good reference) the joints and motors of the Canadarm2 robotic arm on the ISS are so light weight, that it cannot even lift itself while under earth gravity without either burning out the motors or snapping a joint. These designs are very well suited to simulate or human like motion, and maybe these might be good for certain robotic applications on somewhere like mars, but space based applications (or likely even lunar applications) do not need to be nearly this heavy.

[@RB-kb3tc]

@@maxk4324 With fully reusable rockets like spaceship, I bet the mass constraints on payloads sent to somewhere close (like the moon) won't be quite as stringeant anymore. That arm collapsing from its own weight is a symptom of it being optimized for a specific environment. You could design an arm with the same design and length as the canadarm to move in higher gravity than it currently can by making the sections close to the end of the arm narrower. You could also make the motors (especially those at the extremity) arbitrarily small without losing torque, as long as you compensated by changing the gearing ratio. Doing both of these would both make the end of the arm (and therefore the overall arm) lighter, so that the beginning of the arm isn't bent as much by gravity pulling down on the end. However, the arm would move slower (smaller motors) and would lose rigidity as a result.

While I know a simple U-Joint works in cars and trucks. Do you think there could be an application for the rolling joint you displayed for automotive vehicles.
