These hub mount 90 degree angle brackets mate directly to Actobotics channels and hub mounts and are useful as attachment points. They share the same 0.5" center hole and 0.77" and 1.5" mounting patterns as the channel.
Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.
