Step 1: Clearing a Space

The first step in creating a course for your V5 Clawbot is to clear a space on the floor approximately 3 meters (119 inches) by 1.25 meters (49 inches). This will be the racing track and allow two Clawbots to race side-by-side at the same time. Mark the space with tape or in some way so that the track is clearly marked with starting and finishing lines.

Step 2: Building a Ramp

The next step is to build a ramp that is as wide as the course (approx. 1.25 meters or 49 inches). The ramp could be constructed using wood, cardboard, or anything available that is strong enough to hold the weight of the two V5 Clawbots. The ramp should have two slopes, first upward and then downward, and should be sloped gradually so that there aren't gaps at either end of it.

Step 3: Positioning the Ramp

Move the ramp to the second half of the course. The ramp should be at least 1.5 meters (59 inches) from the starting line. Make sure the ramp is positioned so that its sides are precisely parallel to the sides of the track. In other words, make sure that the ramp is not crooked so that the V5 Clawbot's front wheels can reach the ramp at exactly the same time.

Step 4: Preparing the Robot

Power on the V5 Robot Brain, make sure it is paired with the V5 Controller, and run the Drive program on the V5 Robot Brain so that you’re able to wirelessly drive your robot with the V5 Controller.

Step 5:  Running with a Resting Arm

The V5 Clawbots should have their arms all the way down in the starting or resting position.

 

Step 6: Running with an Angled Arm

During the second round, the new pairs will race their Clawbots again head-to-head.

In this round, each Clawbot's arm must be raised at least 25.5 centimeters (approx. 10 inches) above its starting position.

Step 7: Running with a Near-vertical Arm

During the third round, the V5 Clawbots' arms must be raised 38 centimeters (approx. 15 inches) above its starting position.

If you have just two teams, the team who wins Round 3's matchup is the winner of the challenge.
