	Open the `simplebot.js` source file and look for variables that set the left and right wheel zero positions at lines 9 and 10. The theoretical centre value is 90, but you may need to change it to a value between 87 and 93. In very unusual worst case scenarios it may need to be adjusted as far as 80 or 100.

	If you notice that your bot doesn't sit still, but instead creeps slowly on one or both sides, that's a result of the position potentiometers in the servos not being properly tuned. It's possible to disassemble the servo and tune the pots, but you can also compensate in software. Open the `simplebot.js` source file and look for variables that set the left and right wheel zero positions. The ~~default~~ value is 90, but you may need to change it to a value between 87 and 93. In very unusual worst case scenarios it may need to be adjusted as far as 80 or 100.

			SimpleBot uses a combination of the Raspberry Pi (running Linux) and an Arduino-compatible board called the PiLeven (running Firmata) to control the robot and read from sensors. The SD card image provided in the kit includes the full Arduino IDE and supporting tools to allow you to develop Arduino code directly on the bot and upload it to the PiLeven.

			The NodeBots examples rely on the PiLeven running a sketch that implements the "Firmata" protocol, which slaves it to the Raspberry Pi and communicates via serial. This effectively turns the PiLeven into an I/O board for the Pi, providing a standard protocol for the Pi to access the PiLeven's header pins and devices that are plugged into it.

			Before running the NodeBots examples, the PiLeven needs to be flashed with firmware called `SBSFirmata`, which is a version of Firmata that specifically supports the features of the SimpleBot Shield provided in the kit.

			Build and install Firmata on the PiLeven by running the following commands on the Raspberry Pi:

	cd ~/simplebot		cd ~/simplebot
