- Animats 6y agoNow that's a more modern way to use a four-bar linkage. The ASV used it to simplify the kinematic problem, which is doing arithmetic with big steel connecting rods. That little quadruped is using it to get two degrees of freedom without the first actuator having to carry the mass of the second one.
- jcims 6y agoHey you might know this. Is there a term for using what effectively a differential gear arrangement to get two axes of motion as shown in the arm in this video (twice actually, for axes 2/3 and 4/5)? https://youtu.be/ri8kwOCJnY8 https://youtu.be/ri8kwOCJnY8
