goBILDA is based on metric measurements using M4 hardware. The hole pattern has 4mm holes on 8mm grid.
The kit is primarily structured around U-channel, which is strong and durable.
goBILDA’s robust motion system allows teams to easily build drivetrains and mechanisms without worrying about placement and tensioning.
It is arguable, but goBILDA has likely a low learning curve due to its simple yet extremely functional catalog of parts.
goBILDA parts can generally be easily adapted to other kit parts such as REV.
Additionally, goBILDA is still being developed at a quick pace and is responsive to the needs of the FTC community.
goBILDA offers a 25% discount for FIRST teams.
The primary structural component is the 48mm aluminum U-channel, shown below.
In addition, low-side channel (smaller profile channel) complements full size channel. Low side channel is just 12mm in height and allows for more compact builds. Additionally, low side channel opens up possibilities such as a kit-based parallel plate drivetrain. Low side channel also forms the basis of the cascading kit with a 2 or 4 stage option.
goBILDA’s kit is a solid, albeit slightly more expensive, option for new teams. It offers a great deal of flexibility and part options from their catalog. goBILDA is a solid choice due to reasonable pricing, low learning curve, and thought-out design that reduces headaches.

goBILDA’s low-side U-channel opens up many new possibilities due to its flexibility and compactness. For example, one can now make a parallel plate drivetrain without custom machining, or make custom width U-channel.
goBILDA also has Servoblocks (identical to Actobotics other than hole pattern) which drastically increase servo life.
goBILDA also is able to interface with TETRIX channel because they share some holes. For more information about TETRIX-goBILDA compatibility, check out this website. It is also quite compatible with REV’s ecosystem.
goBILDA has some special parts are unavailable in other systems, like square beam shafts.
goBILDA provides a large selection of 12V DC motors. Their Yellow Jacket motors use orbital gearboxes and are available in 10 different gear ratios ranging from 30 RPM to 1620 RPM. No other manufacturer offers such varied gear ratios out of the box.
goBILDA is not the cheapest build system; it is relatively equivalent in pricing to Actobotics, but REV is cheaper.
Because of metric pattern spacing, goBILDA utilizes 8mm pitch chain, as opposed to the FTC standard #25 Imperial chain. This means that other kits’ chain and sprockets won’t work with goBILDA chain and sprockets.
