Hi Routiful Some qns: 1) why does the waffle need 2 sensors are there any differences in their roles? 2) can I install 2 more dynamixel actuators to boost the speed and payload of the turtlebot3? 3) I read somewhere there are only 3x RS485 ports in the OpenCr. How many dynamixel can the OpenCr controls? Thanks in advance! Cheers --- [Visit Topic](https://discourse.ros.org/t/is-turtlebot-the-right-platform-for-us/1892/25) or reply to this email to respond.
