US Digital Designs provides support for the Brooks Automation Orbitran, ZBot and ZBot II wafer transfer robots, as well as our own improved model, the ZBot II+.
We don’t just fix it. We make it better.
Are you experiencing any of these common issues with your Orbitran or ZBot robots?
Z-Axis and Theta drive motors fail
Extend/Retract motors and transmissions fail
E/R cable harness assembly have problems
Wafer Detection / Vacuum PCB problems
Main (Through Body) wiring harness
Reduction gear assembly wears out
Repeatability and accuracy shortcomings
- Unacceptable downtime
We’ve partnered with Brooks Automation, Inc. to tackle these problems head-on, and our collaboration has resulted in a totally revitalized ZBot product line. ZBot customers who work with USDD to refurbish their units report minimal downtime, decreased turn time, and increased satisfaction.
When we refurbish your ZBot, we enhance the unit to meet our own design-improved specifications for that particular model. Alternately, you can choose to replace your ZBot I or ZBot II with USDD’s ZBot II+, a new-manufacture unit with improvements that go beyond the upgrades we offer for ZBot II refurbishments.
All ZBot II and II+ units can drop-in replace each other, and the ZBot II+ can drop-in replace the ZBot I.

Semiconductor Robot Quality Assurance
USDD is committed to continuous quality improvement for our ZBot and Orbitran product lines. Our experience and expertise is a definite advantage but the true advances come from our relationships with Brooks Automation Inc., our suppliers, and the robot end users.
Listening and working with the end users is a fantastic source of knowledge. We strive to continuously improve our products by attacking the sources of ware and fatigue. Our test stand apparatuses allow us to test the robots for basic operations or even extreme conditions when necessary.
Every robot spends a minimum of 24 hours on a test bench. We physically pass thousands of wafers, monitoring repeatability, accuracy and reliability. In addition, we can test new ideas to improve the robots under conditions very similar to field operation.
