Power Levels (optional)
The “Move Tank” block also has two power level input ports, which allow you to control the speed of each motor. By default, the power levels are set to 100, which means the motors will run at full speed. If you want to make the robot move more slowly, you can lower the power levels.
Direction
The “Move Tank” block has two direction inputs, one for each motor. By default, the direction inputs are set to “Forward.” If you want to make the robot move backward, change the direction inputs to “Backward.”
Units
The “Move Tank” block has two units input ports, one for each motor. By default, the units are set to “Degrees.” If you want to make the robot move a specific distance, you can change the units to “Rotations” or “Seconds.”
Example Script
Here is an example script that uses the “Move Tank” block to make the robot move forward:
“`
move tank forward at power 100 for 1 rotation
“`
This script will make the robot move forward at full speed for one rotation.
Setting Motor Parameters for Forward Movement
1. Initializing the Motor Object
First, you need to initialize the motor object that controls the forward motion of the Spike Prime robot. This is typically done using the `Motor()` constructor, specifying the port and the direction in which the motor will rotate.
2. Setting the Power
To make the motor move forward, you need to set its power to a positive value. This value determines the speed and strength of the motor’s rotation. The power can be set using the `set_power()` method.
3. Determining the Direction
The direction in which the motor rotates is determined by the `direction()` method. You can specify whether the motor should rotate clockwise or counterclockwise for forward movement.
4. Configuring the Brake Mode
The brake mode specifies what happens to the motor when it stops receiving power. You can choose between two options: `HOLD` (holds the motor in place) and `FLOAT` (allows the motor to rotate freely).
5. Setting the Ramp Time
The ramp time determines how quickly the motor increases and decreases its speed. A longer ramp time results in a smoother motion, while a shorter ramp time gives a more responsive movement.
6. Monitoring the Motor
You can monitor the motor’s current speed and position using the `get_speed()` and `get_position()` methods. This information can be helpful for debugging or fine-tuning the forward movement.
7. Stopping the Motor
When you are finished with the forward movement, you can stop the motor by setting its power to 0 or by using the `stop()` method. The brake mode you have configured will determine how the motor behaves after it stops.
Motor Parameters Table
| Parameter | Description |
|---|---|
| Power | Sets the speed and strength of the motor’s rotation. |
| Direction | Specifies the direction in which the motor will rotate (clockwise or counterclockwise). |
| Brake Mode | Controls what happens to the motor when it stops receiving power (HOLD or FLOAT). |
| Ramp Time | Determines the rate at which the motor accelerates and decelerates. |
Troubleshooting Common Movement Issues
1. Ensure Correct Wiring
Inspect all cables connecting the motor to the Smart Hub and ensure they are firmly seated. Check for any loose connections or damaged wires.
2. Check Motor Power
Verify that the motor is powered by connecting it directly to the Smart Hub and observing its movement. If the motor operates correctly, the issue may lie in the code or the physical structure.
3. Examine Object Obstructions
Ensure that no objects are blocking the movement path of the robot or restricting its wheels from rotating freely. Clear any obstacles or reduce the size of the robot to fit through narrow spaces.
4. Inspect Wheel Alignment
Check that the wheels are aligned correctly and perpendicular to the ground. Adjust the wheels’ positions if necessary to ensure smooth and balanced movement.
5. Calibrate Sensors
If the robot moves in unexpected directions, recalibrate its sensors by placing it on a flat surface and running the sensor calibration program.
6. Check Surface Traction
Consider the surface on which the robot is moving. Adjust the wheels or use different treads to enhance traction and prevent slipping.
7. Reduce Motor Speed
Setting the motor speed too high may cause instability. Experiment with lower speeds to optimize movement and avoid potential collisions.
8. Ensure Proper Grip
The robot’s tires or treads should provide sufficient grip for the surface it is moving on. Consider using rubberized wheels or treads to increase traction.
9. Troubleshooting Complex Movement Issues:
In cases where the robot exhibits complex movement patterns (e.g., erratic turns, side-to-side motion), consider the following advanced troubleshooting steps:
- Check Advanced Sensor Calibration: Use the Spike Prime app’s advanced calibration feature to fine-tune sensor readings and improve movement accuracy.
- Examine Program Logic: Analyze the code and ensure that the movement instructions are logical and correct. Consider using debugging tools to isolate any potential errors.
- Verify Power Sources: Ensure that all motors and sensors have sufficient power supply. Check battery levels and consider replacing or recharging them if necessary.
- Inspect Mechanical Components: Disassemble the robot and check for any loose connections, damaged gears, or broken parts. Reassemble the robot carefully to ensure proper functionality.
- Contact Technical Support: If all troubleshooting steps have been exhausted and the issue persists, consider reaching out to Spike Prime technical support for further assistance.
