Here a small film on how to Program a Trajectory on a Defined Plan … then we 3D Change Referential Position and we perform the same Program. Whats Up, Doc ?

Experiment in Progress.

Is’nt it Fun to be an Engineer and think in relative 3D space without beeing Einstein ? Do Financials think it’s a loss of public money ?

Let’s remember, technicians, that in 1969 an engineer waited that his auto-navigation computer controlled 3D attitude, altimeters, 6 relative speeds, radars, with a 0.000079 Gbyte ROM Program ! Then after a while this very cool pilot took his joïstick to change the automatic trajectory to « moon » on a plane position.

What’s up since 1969 ? How are technologies progress ? [CIPRIA-2017]

# Explanation ?

First time we define initial position for robots arm. This is the small blanc object at the right hand of robot. We said it to touch it sometimes. Then we define two axis on a 3D space. We have got :

• $PlanPosition0=(O_0,O_0X_0,O_0Y_O)_{O_0Z_0}$ The $Z_0$ position is implicit on the program.

Second time : You perform algorithm to calculate trajectories ON this plan : for exemple a Circle and a Star on it.

Third time : You define another Plan in a 3D Space.

• $PlanPosition1=(O_1,O_1X_1,O_1Y_1)_{O_1Z_1}$ then you write : « Set to 3D Plan 1 » and you run the previous trajectories program.

That’s All Folks ? Sure Not !
