Servo Mount - Servo Plate A

This servo plate allows you to attach gears and mechanical structures to your standard sized servo. There are 4 6-32 tapped holes for mounting your servo, and numerous other holes for attachment. The plate utilizes both the 0.77" and 1.5" hole patterns for Actobotics and has 2 0.5" holes for mounting bearings or shafts. For attaching your servo, we recommend 6-32 1/4" screws (not included).

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.

    Found the issue - jumbled organization of the product categories at HK. And the flat 2D CAD drawings there provided that confirmation. :-) (couldn't resist...)

    We all appreciate SF's efforts at documenting the mechanical aspects of the products. I've seen in the comments sections that it's been a work in progress for some time.

    • This is very true, we have been working on it for awhile, but it's a huge project and we want to do it right. We have a meeting next week (for what it's worth) discussing a potential solution. Just a few years ago, we didn't post eagle files, schematics, github, or sometimes even datasheets. We've come a long way since then, and we still have a lot more to do.

    Just a note to everyone to be careful about servo size names. What SparkFun calls a Standard servo is what Hobby King calls an Extra-Large. The Standard servo I bought from Hobby King is unusably small inside this mounting plate. The bottom line is that dimensions need to be checked carefully before ordering because an item name can be misleading. Between HK and SF I'm not sure who's using nonstandard terms.

    While we're on the topic of documentation, Having Sketchup drawings alone for mechanical drawings is inconvenient. Yet another application to load onto the several PCs I use to access this site. PDFs work just fine for me and it would be good customer service to make those available too. Thanks for listening.

    • we are working on better 3d files. something will be coming soon (hopefully). for 3d parts, PDFs tend to be inadequate as it's hard to show where every hole is, how big, etc. A 3d design program is becoming more and more essential anymore.

      In regards to motor sizing, we follow the standards that Hitec uses, as well as many other well-known brands. I'm not sure what Hobby King is doing.
