Reality check

A demo shows what may be possible. These points help judge whether the product fits day-to-day use.

Works well when
  • Stable, repetitive handling, tending, welding or assembly
  • Processes with known parts, fixtures and cycle times
  • Cells where an integrator can own commissioning
What to check
  • Payload after adding the gripper and cables
  • End effector, vision and safety-cell cost
  • Changeover time when the part or fixture changes
Not a magic solution
  • A solution for a process that changes every day
  • A turnkey cell without integration and safety work
  • A reason to skip measuring the current process

About

Z1 is a six-axis arm designed to mount on mobile robots, including AlienGo and B1. Z1 AIR is approximately 4.3 kg with 2 kg payload; Z1 PRO is approximately 4.5 kg with a payload stated as at least 3 kg. Both have 740 mm reach and approximately 0.1 mm repeatability, subject to test conditions. Ethernet, Ubuntu and position/force control are listed; the 405 g joint-module specification is not the weight of the complete arm.
