Our robot has a three wheel (6 really) l, elastic collection setup. The entire front end “opens” up to allow for the larger size purple blocks, and then collapses back in to accommodate the greens. Sort of expanding. I think most of you know what I mean. Sometimes, not all the time, it has a difficult time lifting and loading up the purples.
It seems like, the pressure the motorized gear wheels and elastics don’t have enough torque to pull the purple and force the weight of the front “expanding” mechanism forward to actually allow the purples to be pulled up.
Anyone follow what I’m saying and have experience, suggestions, solutions. Etc?
Thanks
