Advantages of Dynamixel X -T / -R TTL vs RS-485

asked 2019-02-06 11:16:44 -0500

I'm planning to buy servos for a humanoid robot that I control with ROS, is there any disadvantage of the TTL vs RS-485 versions? EMC/Electric disturbance / how many servos on one line/bus are possible... or others?

Thank you for your inquiry about Dynamixels.

Simply, the advantage of using RS-485 is more robustness when you need to long long communication line. If you have a plan to make humanoid robot, you could use TTL rather than RS-485. And you can use Dynamixels up to 200 connected with additional power.

I think below link might good example for you.
