UX Frustration with robotics controls

As a UX person I find the robotics limit sliders really frustrating. I must have spend ten minutes trying to set this back to 0.0 instead of -1, -4, 2, 5, 2, 1, -1.

There are two obvious solutions to this

1. Snap to round numbers (0,5,10) and allow a toggle on precision mode
2. Allow text entry of values
