Personally, I dislike COTS items like this, a complete bolt on solution. This is different than small components like gearboxes, wheels, structural members, etc. Those still require work to configure and optimize, the Kitbot is a starting point, a way to at least get you to the event and on the field. Things like the Greyt claw & lift, the REV lift, etc short circuit the learning process, as a current college student I can tell you that looking at the worked out solution and understanding it is not the same as solving the problem on your own and getting help when you are stuck.
When I was a student we built everything custom, it often broke at competition, and while I enjoyed fixing it in a rush, it was a miserable experience for most of our team. The students who graduated from that era have stayed in stem in spite of their experiences, they weren’t inspired by it. Since I graduated the team has adopted a new philosophy and uses a lot of cots components, mostly things from McMaster Carr, Lowe’s, and Home Depot. Linear elevator? Built our own out of garage door track and rollers, worked great, and parts were available at most hardware stores. Ratcheting mechanism to stop the climber from back-driving, broached a nut for the shaft and bolted a Gearwrench on. My experience in three years of Co-ops has been that this is how a lot of engineers do their job, it’s about finding something close to what you need and tweaking it from there, this is an important skill that complete cots solutions deprive the students of.
(The real issue is how do we help a team that only cares about one aspect [Programming] do more of what they care about while not creating an environment where a [Robot] team can’t compete/win, or vise versa)
