1. Set the Robot's Speed

Just like a car, a robot can move fast or slow. You can control the speed that the robot is moving with the setSpeed block. It has one input value, which is the rate the robot is moving, in inches/second:

You can use a setSpeed block at the beginning of the code to set the speed for all later robot movements. You can also add a setSpeed block before any driveDistance block to specify how fast the robot should drive for that distance:

Later driveDistance blocks in the code will use the speed set by the most recent setSpeed block.

You can test the time it takes for the robot to go different distances at different speeds by using the timer to see how long it takes for a program to run. (The timer is in the middle section, just below the trash can icon.)

2. Maximum Speed

 IMPORTANT: If you are using hardware Linkbot robots with the regular blue wheels, the maximum speed is around 6 inches/second. But they work best at 4-5 inches/second or less.
