    Anyone want to collaborate on a project?

    I just stopped by and it's crazy to see everyone who is still around. Feels like it's been forever.

    I currently don't have time/money to put together a new mech project, but if somebody wants to...

    Also, you should not change dxl_hal.c if you are using the USB2Dynamixel. You only need to modify that if you are using Xevel's USB2AX.

    Re: New Mech: The Kevin

    I'd go with interpolation, it seems to be the preferred method. The Bioloid library has interpolation functions that are really easy to use, so you probably wouldn't have to write too much code.
