Direct Control:
- Control Using pushbutton
program- download here or

- move a ball from one tire to another
Note how complex and tiresome this gets......
- Control using recorded movements- add parallel sequence to record and play back movements.
Note that if you want an action to repeat (as on many industrial robots) you need to return the mechanism to its original starting position at the end of the teaching sequence.
See notes on NxT-G Record Block.
Real-World Examples:
- assembly line robot
- welding robot
- Agilent BenchBot Plate Handling Robot
- Baxter Robot- Rethink Robotics
Servo-Control:
Robot mimics movements of operator.
Examples:
Supervisory Control:
In supervisory control, the programmer wants the robot to be able to respond semi-independently- the operate sets general goals, while the robot autonomously avoids obstacles, controls motors, etc.
- Mars Rover Navigation
- Hovering Flyer- MIT
- Bomb
disposal Robot
Write training program for three movements, which incorporates on-screen displays, beeps, etc.- robot performs various trained movements in response to different stimuli
