Modify ForwardTenSeconds so that it makes your BOE Shield-Bot go straight forward. Use masking tape or a sticker to label each servo with the best us parameters for your writeMicroseconds (us) function calls. If your BOE Shield-Bot already travels straight forward, try the modifications just discussed anyway, to see the effect.
How do I make the BOE shield-bot turn?
You can make the BOE Shield-Bot turn by pivoting around one wheel. The trick is to keep one wheel still while the other rotates. Here are the four routines for forward and backward pivot turns: Save ForwardLeftRightBackward as PivotTests.
Would your Boe shield-bot travel in an arc instead of straight line?
So, would your BOE Shield-Bot travel in an arc instead of in a straight line? Top speed varies from one servo to the next, so one wheel is likely to rotate a little faster than the other, causing the BOE Shield-Bot to make a gradual turn.
What programming language is the BOE-bot programmed in?
The robot’s BASIC Stamp brain is programmed in PBASIC, a simple text based language where each line in a single file performs a single task, with nothing hidden or abstracted in libraries. The Boe-Bot kit includes a 360 page spiral-bound book Robotics with the Boe-Bot (also a free PDF download).

What people say about the Boe-Bot Robot
We strive to provide the best products and support for all of our customers.
What does it mean when your shield-bot is curved?
If your BOE Shield-Bot curved to the right instead of the left, it means you need to slow down the left wheel.
What does it mean when a BOE shield turns left?
Let’s say that your BOE Shield-Bot gradually turns left. That means the right wheel is turning faster than the left. Since the left wheel is already going as fast as it possibly can, the right wheel needs to be slowed down to straighten out the robot’s path.
Does the BOE shield go straight forward?
If your BOE Shield-Bot already travels straight forward, try the modifications just discussed anyway, to see the effect. It should cause the BOE Shield-Bot to travel in a curve instead of a straight line. You might find that there’s an entirely different situation when you program your BOE Shield-Bot to roll backward.
