hello, want to build a real strong robot arm with Hitec D980TW servos. which are the right brackets for this servo from robotshop?
thank you
@tobolon Welcome to the RobotShop Community! Don’t know of any brackets made for this servo.
For example, in order to check to see if this servo is compatible with Lynxmotion brackets (for example standard brackets), the dimensions need to be almost exactly that of the Hitec HS-422. The 422 is 40.6mm wide at the base, whereas the D980TW si 43mm at the base and therefore won’t fit:

Unfortunately the large brackets from Lynxmotion are too large, and the micro brackets are too small. ServoCity / Actobotics / GoBilda does not seem to offer any such brackets either (feel free to search a bit more in depth). In this case, the only option is something custom (ex. 3D printed).

thank you. can you give a recommendation which servo with bracket is the strongest in the product line of robotshop and available from the dutch retailer?
Can you describe your application a bit? A sketch / drawing might help.

looking for servo motors with brackets (to have two fixing points instead of one) as strong as your product line can go. i attached a picture. these servos can crawl when the object lies on the ground but they are not strong enough to lift the leg or the arm in the air (and more body parts to come) just direct me to the strongest items you have and i would be very happy.

The “two point” contact would be the C-bracket.

Lynxmotion brackets are all anodized aluminum, and the micro brackets are the same thickness as the large brackets. It sounds like it’s less about the brackets and more about the torque of the servos. The most powerful servo in the Lynxmotion lineup is the LSS HT1:

This works with the SES V2 brackets:

There’s a chance that they might fit the same way as your current servos (i.e. the are closer to a standard RC servo than a “large” or “mega” sized servo.

thank you very much! i will give the LSS HT1 a try. did i get it right that it is completely configurable and programmable with arduino controllers when using the special LSS library and the given examples? or do i need something additional like the software to get it operating?

Indeed, it’s fully configurable and the communication protocol is easy to use. Suggest using the LSS Adapter: https://www.robotshop.com/en/lynxmotion-lss-adapter-board.html
You can mount a shield-compatible Arduino below this using the included headers.

is there a tutorial or diagram how to connect the LSS to an arduino board without that adapter board? is it just rx/tx connected to tx/rx on the arduino and bypassing the power lines or more complicated?

The connector on the LSS can’t be plugged directly into the Arduino, so yes, you’d have to connect Tx-Rx, Rx-Tx, and GND, while V and GND are connected to the power source.
