That was around 10.7
Guys, sorry to break it to you but that wasn't a 9.57 or faster; it was more like 11 seconds.
What is this machine
i will need one with higher torque compensation , so will that be possible? Can we buy one or will need to make one by myself( resources reference).Thanks in advance.
ahhh very simple idea! Great work! I should've thought of this one!
Forks on springs, pushed by springs
캠 구조와 스프링을 사용해서 중력보상을 한건 정말 흥미로운데, inertia가 많이 걸려있는 고속 메니퓰레이션 작업에선 보상력이 시스템의 동작에 어떤 영향을 줄지 궁금하네요.
좋은 포인트입니다! 저희도 궁금해서 매니퓰레이터에 적용해버고 있어요. 곧 결과가 나올텐데 기대해주세요^^
Yeah good onya cobba
oh interesting. so the cartioid shape of the cam means that the most spring resistance is applied when the arm is upright and the least when the arm is pointed downward. very interesting. is there any tactile "click" as it seats into the dip on the cam?
Hello, may I know what kind of software you use for this experiment?
Cool but you can just add a spring to the robot arm and do the same.
Yeah, an constant force spring
do you have a 3d cad model to look at to really understand the movement?
Please do check our differential mechanism: Modular Pipe Climber III with Three-Output Open Differential (IROS 2021) ruclips.net/video/R6T9UD7t5uY/видео.html
could you adjust the counterbalance force when the arm isn't upright?
That's a good question. Yes, it is possible but the adjusting motor needs to use more energy since in that case the motor need to push the spring together when adjusting the pivot position.
@@cauassistiveandrehabilitat7285 thx. 5Nm compensation out of such a small form factor is very impressive. I have seen another variable compensation design that is massive. Still, is it possible to add a compensation to the adjustment linear actuator so that the motor needs ~ 0 torque to adjust the leverage at an angle of, for example, pi/2? This would be very useful in situation like workers loading and unloading around a similar elevation.
