Four things to read before you issue a purchase order
A buying checklist, a primer on degrees of freedom, a landed-cost method and an RFQ that gets usable answers.
Guide
How to buy a dexterous robot hand
Nine checks, in order. The first one eliminates more purchases than the other eight combined.
Primer

Three counting conventions, one hand. The number on the spec sheet is a decision about what to count, not a measurement.
Guide

The list price is the first of six numbers. For a $5,000 hand, the other five can add a third again.
Template
