Core Skill: Robotics

This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.

3 Robotics

Skill Level: Competent - You may need an understanding of servo motors and how to drive them. Additionally, you may need some fundamental understanding of motor controllers.

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.

1 DIY

Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Customer Comments

  • Are you sure this has 180 degrees rotation? From the datasheet, it sounds like only 45 degrees. Or dies “operating angle” mean something else?

    • This is actually something that appears to be oft-discussed in hobbby RC forums. Just as a summary: These are hobby devices with varying amounts of error (i.e. you’ll always want to send pulses and get the actual angles and compensate in code accordingly). The 45 degrees refers to a single direction. This implies that it has a 90° range if you take both directions. However, that’s is assumed to just be what the manufacturer is willing to state as being the range that they’ll ‘guarantee’; in practice many have found the range to be 180° .. or nearly that (e.g. 178°). And if that makes you think “ugh.. then how am I supposed to figure out what the actual range is?”, it looks like you could form a club with similarly frustrated people :) Your best bet seems to be to google the part and check people’s actual findings (keeping in mind that yours may vary somewhat).
