Linkage sizes for optimization of climbing motion

 

Am trying to design a wall climbing robot using a 4-bar linkage mechaism but cant find any info on what linkage lengths will optimize the whole climbing motion. i tried using 8 legs; 4 internally and the others outside the body frame to try and prevent rocking

Some pictures or references

Some pictures or references to what you are trying to do would be really helpful.

references for 4 bar linkages

There are many 4-bar linkage

There are many 4-bar linkage designs that can be used to optimise different properties.
Are you looking for maximum stride length? High strength? Low profile?

The photos you’ve supplied doesn’t give a very good indication of the overall design, and it is impossible to discern the feet/claws/whatever that the robot will be using to stick to the wall.

stride length will beof

stride length will beof great importance since the robot climbs a fence not a wall and i thot of using a hook as the end-effector of each leg since we have very limited programming allowances
