Initial Startup - 2008/01/24 00:46 Our PCBOT is continually restatrting itself. If we turn the system completely off we are given the startup screen where we get to choose our operating system. After this step, the systme goes in a loop where it restarts itself over and over. Any assistance is greatly appreciated.

Re:Initial Startup - 2008/01/24 00:56 Is this running from battery power or external power?

The charger supplied is not up to the job of powering the bot - only for charging the batteries, so it must only be plugged into the charger socket, rather than the ext power socket. If you plug something into the ext power socket it disconnects the batteries, and the M2-ATX PSUs fitted will shut down the system if the voltage drops too low...

Re:Initial Startup - 2008/01/24 09:59 If you don't get it to run, it might be good to check the battery voltage without the charger attached. Look for the big connector between the base and torso in the front, that's a good place to poke your meter leads. Then attach the charger and read the voltage again.

The first measurement tells you if the battery is generally OK, maybe dead, or the fuse is blown. The second measurement tells you if the charger current is reaching the batteries.

Re:Initial Startup - 2008/01/24 16:41 I find that a 15v DC PSU that can deliver about 5Amps is enough to both charge the batteries and power the computer + all extra electronics.

When I write software for my robot I sometimes keep it switched on the whole time but charging like this.

Re:Initial Startup - 2008/01/25 23:33 Had the same issue. This was due to a low votage situation with the batteries. If you first fully charge your batteries (with the 'bot off), then turn it on, do you still have the same issue?

Re:Initial Startup - 2008/01/29 09:02 Ted,

Make sure that the robot is fully charged. What you are experiencing is most likely what Lilly the robot also experienced.

With your robot off, plug in the charger. If the batteries in the robot are low, the LED on the charger should turn amber when charging and once fully charged will turn green.

If you turn the green toggle switch at the front of the robot off. i.e. The M3 switch, you should be able to use your PC-BOT in perpetuity with the supplied charger, however, that does depend on what type of applications you are running on the robot.
