As a first stage this can be done using only whatever vision system
you use and LinuxCNC.
It is easy enough to send an "MDI" command to LinuxCNC that w
Andy,
In the case of a robot arm you need to send (x, y, z, w, x, y) where w, x,
y are rotational orientation.
QUESTION: Can we also send the speeds for each target point (x', y', z',
w', x', y'). What about acceleration like x'' ?
Correct me, But I think this could be done using LCNC's trivial

LinuxCNC would normally use xyzabc. Using x and y twice would confuse it.

Checking and stopping is not good enough. A robot has to be able to "try"
multiple solutions to the problem before it executes the movement plan.
For example: It has been told to fetch a bottle of beer from the 'fridge

Robots are not kids. Robots can programed to load a dishwasher or clean
