Actobotics

Actobotics

Actobotics® is a ball-bearing based, precision building system. It is manufactured by RobotZone®, LLC (ServoCity's parent company) and distributed worldwide.

Actobotics® components are...

  • Precise. Components utilize ball bearings, precision shafting, and tubing, resulting in a superior structure with tight tolerances and low friction.

  • Compatible. Standardized sizing allows the use of non-Actobotics components including servos, motors, actuators, and R/C vehicle components.

  • Innovative. The unique overlapping hole patterns allow for virtually unlimited mounting possibilities.

  • Progressive. The Actobotics product line consists of hundreds of individual components and continues to expand at a rapid rate.

  • Robust. High grade aluminum and stainless steel components provide a rigid foundation.

  • Mobile. Create mechanical motion using gears, sprockets, chains, belts and pulleys.

  • Intuitive. Easy for both the experienced engineer and novice hobbyist to design and build projects.

The versatility of these components make them useful for all kinds of projects and applications.

Overlapping hole patterns offer extreme versatility when designing and building structures. Check out these attachment ideas.

Actobotics Hole Pattern Information

Actobotics Hole Pattern Information

The 0.770" Actobotics hole pattern

The Actobotics line of components utilizes two different hub patterns. The smaller of the two hub patterns measures 0.770" center to center across the middle of the pattern. The 0.770" dimension has been chosen so that when a component is attached to the pattern with pan head or socket head screws, the ½” center bore is left unobstructed. This pattern is repeated down the entire length of the channel with a .750" spacing from one center hole to the next. While most screw holes in the channel measure .140" in diameter, the shared hole in-between the ½" center holes must be slightly oversized (.160") to allow them to properly align. Both the 0.140" and the 0.160” holes work well with the common 6-32 fastener sized used throughout the Actobotics line.

The 1.50" Actobotics hole pattern

While the 0.770" pattern is excellent for the majority of construction projects, there are times when a larger pattern is advantageous. The 1.5" hub pattern is measured diagonally across the middle of the pattern. Just as the 0.770" pattern is repeated along the channel around each ½" center hole, so is the 1.5" hub pattern. One common application where the 1.5” pattern is used would be the Actobotics motor mounts. Many of the mounts utilize the 1.5" hub pattern to attach the motor to channel in order to increase side stability and spread the load out on the channel.

Since the 1.5" distance is the diagonal dimension (considered the hypotenuse if you create a triangle that passes diagonally through the center to opposite corners), each side dimension of this pattern is slightly shorter. The sides measure 1.0607". Many of our mounts utilize this 1.0607” dimension derived from the 1.5" hub pattern. Components with the 1.0607" pattern can be mounted upright inside the channel or flat across the top of the channel.

The 1.5" pattern also leaves room for a large center bore through components such as clamping hubs, bearing mounts and adaptors. Our 1" clamping hubs utilize this pattern so that the 1" OD tubing can slide through the hub without obstructing the center bore for routing cables and wires.
