/* This test is build for use with the Motorized Bulldozer (8275).
* You need about 1m x 0.5m space where the Bulldozer will drive.
* Because we don't have motor-feedback or encoders, all times are
* approximately and depending heavily on the battery-level of the PF
* and the ground over which the bulldozer drives.
*
* It should'nt be any problem to use this test with other models or
* just plain connected motors to see if all works.
*
* Maybe I've made a mistake building the bulldozer, but my model
* requires to backward drive motor A on channel 0 to drive the left side
* forward, it might be that you have to change that.
*
* The sequence of commands is the following:
*
* (1) Backward drive motor A (red, blade) and forward drive
* motor B (blue, ripper) on channel 1 with full power for 7s to
* be sure the front blade and the ripper are up.
* (2) Forward drive motor A (left) and backward drive motor B (right)
* on channel 0 with full power for 5s to drive the bulldozer
* about 1m forwards.
* (3) Forward drive motor A on channel 1 for 5s then backward drive
* him for 5s to move the front blade down an up.
* (4) Forward drive both motors on channel 0 with full power for 3s to turn
* the bulldozer to the right about 180 degrees,
* (5) Forward drive both motors on channel 0 pwm-controlled, raising the
* power from 3 to 6 and backwards to 0 to drive the bulldozer
* about 1m forwards.
* (6) Backward drive both motors on channel 0 pwm-controlled with power 7
* to turn the bulldoze to the left about 180 degrees.
* (7) Backward drive motor B on channel 1 for 5s then forward drive
* him for 5s to move the ripper down an up.
