I am designing a robotic arm, and am wondering how can I determine if a certain part is strong enough and how could i determine if I have enough torque, also really any feedback would be appreciated. I took inspiration for cycloidal drives on joints 2 and 3 from arctos robotics arm. those cycloidal drives have a reduction of 25 to 1 but with pulley joint 2 will either have a reduction of 100-125. The arm is not yet finished but as i said my biggest concern is will joint two have enough torque and will the parts be strong enough when 3d printed. is uses 3Nm NEMA 23 motors and DM566TE drivers. I know it is generally recommended to start by designing from top to bottom but i really could not do it, felt weird. submitted by /u/toljaga12 [link] [Kommentare]

Where the Saylor Apologists at? submitted by /u/GabeSter [link] [Kommentare]

It’s been 10+ years and crypto/ btc has not proven it self to be useful other than to buy low and sell it to the next person at a higher price hoping the narrative causes the price to rise. 99.99% of people that buy crypto only buy to ope to sell it to the next person at a higher price that’s all it has become . Stocks , realestate other assets classes actually produce some good or service but crypto does nothing …. Look at ADA and Charles lol , poly-GON 🤣🫵🤡. Hope to buy low sell high and bounce . submitted by /u/ozera202 [link] [Kommentare]

Hi everyone, I'm building the original InMoov v1 robotic hand . The mechanical assembly and servo control are working well, but I'm currently stuck with the sensor integration. My goal is to add: Hall Effect sensors for finger position/feedback. FSR (Force Sensitive Resistor) sensors on the fingertips for touch and grip force detection. Ultimately, I want to implement closed-loop gripping, where the hand can detect contact with an object and adjust the grip force instead of simply moving the servos to fixed positions. The problem is that I can't find a proper guide explaining how to do this. I've spent a lot of time searching through YouTube, Google, GitHub, forums, and other online resources, but I still haven't found a complete tutorial that covers the entire process. I'm specifically looking for help with: Where to mount the Hall sensors and magnets. How to mount the FSR sensors on the fingertips. Wiring diagrams. Arduino code/examples. Sensor calibration. How to combine the Hall sensors, FSRs, and servo control into one working system. If anyone has: YouTube videos GitHub repositories Research papers Wiring diagrams Build logs Arduino examples Personal experience integrating these sensors into an InMoov hand (or any tendon-driven robotic hand) I would really appreciate your help. I've been stuck on this for quite some time, so any guidance or resources would mean a lot. Thank you! submitted by /u/Odd-Bell1718 [link] [Kommentare]
