Inchworm mechanism
WebAfter analyzing motion pattern of the robot, we decide to use two clamping mechanisms and a linear locomotion mechanism by simulating the squirm pattern of inchworm. Moreover, we make sure the mechanisms are operating effective and stable by using two-screw for … WebStill, it should be noted that although the inchworm crawler mechanism can be implemented into a lot of soft robot forms or even rigid robot forms that generate similar structure deformation results, the DEA structure is one desirable choice considering its specialties …

WebOct 8, 2024 · We measured nsp13 both as it translocates along single-stranded DNA or unwinds short DNA duplexes. Our data confirm that nsp13 uses the inchworm mechanism to move along the DNA in single-nucleotide steps, translocating at ~1000 nt/s or unwinding at ~100 bp/s. Nanopore tweezers’ high spatio-temporal resolution enables observation of … WebJun 8, 2024 · To rationalize these observations, we propose a helical inchworm translocation mechanism in which, during each cycle, the motor increasingly adopts a lock-washer structure during the ATP loading ...
WebDec 1, 2024 · The structure of a bionic robot is created using the inchworm's motion mechanism as inspiration. And the universal joint's properties are used to realize the robot's multi-motion mode functionality. The forward and inverse kinematics are examined by D-H modeling. The mechanical model of the robot is created by using ADAMS simulation … WebJan 30, 2004 · A kinetic analysis of the dwell times between steps shows that the 17-nm steps alternate with 0-nm steps. These results strongly support a hand-over-hand mechanism, and not an inchworm mechanism. In addition, our results suggest that kinesin is bound by both heads to the microtubule while it waits for adenosine triphosphate in …
WebJan 6, 2024 · Inchworms move with an anchor push-pull strategy, i.e., anchoring their anterior leg and contracting the longitudinal muscles, pulling the posterior leg forward; anchoring the posterior leg and releasing the muscle, pushing the anterior leg forward and following the looping gait.
WebNov 1, 2006 · An inchworm processive mechanism is proposed to explain the motion of dimeric molecular motors such as kinesin.We present here preliminary results for this mechanism focusing on observables like mean velocity, coupling ratio and efficiency versus ATP concentration and the external load F.

Large and distinct conformational changes occur on binding DNA and the nucleotide cofactor. Taken together, these structures provide evidence against an "active rolling" model for helicase action but are instead consistent with an "inchworm" mechanism.
