Using the FIRST® A301 with goBILDA®

Dec 10th 2025

FIRST® recently announced the A301, the future of actuators in FIRST® Tech Challenge. This actuator was created through direct collaboration between FIRST® and REV Robotics and will become legal to use in the 2027-28 season. This new actuator features a 15T thru-bore and functions as both a servo and a motor.

New goBILDA® Parts!

At goBILDA®, we love engineering parts that empower teams to build better robots. We will be offering components that will integrate the A301 seamlessly into the goBILDA® ecosystem. The image above shows preliminary CAD examples of just a few of the many parts in development.

You can look forward to:

  • Adaptors and couplers that allow longtime teams to continue using 8mm REX™ components without missing a beat
  • A full suite of 15T-spline parts, both shafting and bore components, that will bring the goBILDA® magic to this profile
  • A variety of brackets and mounts designed specifically to allow for intuitive, innovative use of the A301

Our top priority is to help teams explore the capabilities of the A301 while allowing them to take full advantage of the flexibility and modularity they value in the goBILDA® system.
