Operating Instructions
The Dynamic Bulldozer is designed for remote-controlled operation, providing realistic movement and functionality.
Powering On
Ensure the 3 Buwizz units are correctly installed and charged. Power on the Buwizz units and establish a connection with your remote control device (e.g., smartphone with Buwizz app).
Driving and Steering
The bulldozer's movement is controlled by the 8 XL motors (2 per wheel). Use your remote control to drive forward, backward, and steer. The 2 L motors manage the steering mechanism via linear actuators.
Pneumatic Bucket Control
The pneumatic system allows for precise control of the front bucket. The bucket can be raised to a maximum height of 64 cm. Use the designated controls on your remote to operate the pneumatic cylinders for lifting, lowering, and tilting the bucket.
