1.2 Additionally required components
For Crash Bobby, a standard model-making rechargeable battery of 7.2, 9.6 or 12 volts can
be used. However, the qfix rechargeable battery pack (order No. QAAC000) is especially
suited to this use since it already contains the required adapter cable and Velcro strips for
simple mounting of the batteries.
For charging the battery, a standard battery charger can be used or, alternatively, the qfix
plug-in battery charger (order No. RBAD000) is available.
1.3 Interesting extensions
The following extensions to the Crash-Bobby kit bring even more fun into your robotics
adventure:
•Line sensor set (No. QAAAB000) for moving along a line.
•Bumper set (No. QAAB005) to react to contact with obstacles.
•LC-display board (No. QAAF001) for displaying arbitrary information.
For beginners in computer programming the graphical programming environment “Grape”
(No. QAAH000) is an interesting tool.
1.4 Reference

Building the Crash Bobby
2.1 Step 1 - Assembling the wheels
For assembly of the wheels, the components shown in the following picture are required:
First of all, the small setscrew should be screwed into the side of the wheel bush. Next, the
wheel bushes should be pushed as far as possible into the wheels, so that the countersunk
screw M4 can be inserted from the other side. This is then tightened with the appropriate
hexagonal wrench.
The assembled wheels are shown in the next picture:

2.2 Step 2 - Assembling the motors
In order that the motors can subsequently be screwed on to the base plate, they must first
of all be assembled on the motor mounts. The required components are shown in the next
picture:
The motors are located in the large recess of the motor mounts and tightened using the
small screws M2x6. Take care with plastic threads – do not overtighten the screws!
Finally, the pre-assembled wheels are placed on to the motor axles and the setscrew is
tightened:

2.3 Step 3 - Assembling the support wheel
For assembly of the support wheel on the rectangular mounting plate, the components
shown in the following picture are required:
The washers are used as distance spacers and are simply placed on to the threaded pin.
Afterwards, the threaded pin is then screwed firmly into the single threaded hole located
in the rectangular plate.

2.4 Step 4 - Assembling the sensors
In order that the sensors can subsequently be screwed on to the base plate, they must
first of all be assembled on the sensor mounts. The necessary components are shown in
the following picture:
The three sensors are each screwed to the mounts using two screws. The next picture
shows the assembled sensors:
