PAROL6 Desktop Robot Arm
I wonder how this compares to the AR4 robotic arm ( <a href="https:&#x2F;&#x2F;www.anninrobotics.com" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.anninrobotics.com</a> ).  The AR4 isn&#x27;t truly hardware open source, but my understanding is that it&#x27;s software agnostic.<p>My biggest question is the full cost for the PAROL6.  Their BOM link is 404.<p>I can build the AR4 completely for less than $2000, and for education, that&#x27;s a very small price for a semi-useful, full 6 axis arm. (Currently, to give a comparison, one of my suppliers is offering an educational cobot solution for $40,000.  Yes, it&#x27;s truly &quot;industrial,&quot; and is a complete self-contained solution, though it&#x27;s only capable of 2kg if I recall correctly.  This was what they were pushing for the educational market.)<p>As someone who is trying to implement robotic training in education, with a budget that approaches zero, I just need something cheap that students can hack&#x2F;break&#x2F;fix without costing a fortune in maintenance costs.<p>One of the cool thing about the AR4 is that it can come as a complete kit, either as 3d printable or aluminum frame. and they work with Steppers Online to provide the steppers and drivers as one package.  If you work for a school system, this type of solution solves a lot of logistical issues.<p>That said, if this thing is truly low cost, let&#x27;s say under $1000, for it&#x27;s capabilities, it could be a very nice project.
