C Control PRO-BOT128 + C-Control PRO 128 Unit + Voltcraft® USB programming cable Kit 190406 Manual De Usuario

This chapter provides an overview of how to handle the robot and the corresponding components. The required detailed information e.g. about
programming is contained in the following chapters of this manual or the descriptions contained in the example programs.

Especially in dry air, the human body and the robot itself may become electrostatically charged (depends on the consistency of the flooring).
When coming into contact with conductive objects, this load discharges with a small spark. Such discharges when touching electronic components
may destroy them. Prior to handling the device, you should touch a large, grounded object (e.g. a metal PC housing, a water pipe or a radiator
pipe) to discharge any possible charges. Discharging the robot on grounded objects is harmless, may however lead to program crashes or
uncontrolled reactions of the robot.

All electric connections from and to the device must always be established prior to connecting the supply voltage. Plugging in or unplugging
connection cables or the establishment or disconnection of connections may destroy the control computer or connected devices. The supply of
the robot requires a direct voltage of 4.8 to 6V, which is generated with 4 rechargeable batteries type NiMH or NiCd. Only use tested chargers
for charging the batteries. If necessary, the robot can also be operated with 4 high-quality alkali-manganese batteries. Due to the higher inner
resistance, current peaks in operation (e.g. when suddenly changing the driving direction) must be prevented by programming when using
batteries.

During construction of your model, adhere to the assembly plan and construction step I. Careful work is essential here to not experience any
unpleasant surprises upon commissioning.

Start with the flattest components (resistors) on the main unit or the bass axes on the drive unit. Then proceed with the remaining components
according to size. The motors, gears, wheels and gliders (ping-pong balls) are mounted in the end. The semiconductors are plugged onto the IC
socket (these are first inserted after testing the circuit).

Then finish the assembly by screwing together the individual circuit board levels by means of circuit board distances. Now you can connect the
circuit board connection cables.

The possibility that something does not work after assembly can be drastically reduced by thorough and clean assembly.

Check each step and each soldering spot twice before continuing!

Adhere to the construction manual! Do not alter the steps described there and do not skip anything! Tick each step twice: Once for
the construction, once for testing.

Take your time in any case. This assembly is not a rush job, because the time spent here is three times less than the time spent on
searching for an error!

One frequent cause for malfunctioning is an assembly error, e.g. wrongly inserted parts like ICs, diodes and elcos. Also observe the colour rings
of the resistors under all circumstances, as some of them have easy to mix up colour rings. In case of doubt, check the resistors with a suitable
multimeter.

Also observe the condenser values, e.g. n10 = 100 pF (not 10 nF). Checking double and triple prevents errors.

Also make sure that all IC pins are properly inserted in the sockets. They might bend very easily when inserting. A small push and the IC should
almost jump into the socket itself. I fit does not, one of the pins may be bent.

If everything is correct here, the fault may be due to a cold soldering spot. This annoying factor mainly arises if the soldering spot was not heated
correctly so that the solder cannot contact correctly with the leads or if you move the connection at the moment it hardens while cooling down.

Such errors can easily be detected by the matt appearance of the soldering spot's surface. The only remedy is to solder the spot once again.
