Bluetooth Rally Racer


Rally Racer is the successor of Rally Rac3r. The difference? This Rear Wheel Drive race car is a tremendous success. As complimented by Karl4123, this vehicle has “sleek and stylish looks.” It is geared up 36:12 or 3:1, and it is decently quick with decent torque. Many styling cues have been added. Why is there no InfraRed Sensor, you may ask! Well, thank you for asking! With the help of Builderdude35’s tutorials, Rally Racer drives via Bluetooth! Rally Racer’s Intelligent Brick acts as a receiver, and a second Ev3 Intelligent Brick is the remote! In this way, I am able to control Rally Racer from 200 feet away. I also incorporated bluetooth RC into prototype versions of my 2010 Cadillac CTS-V Replica

Rally Racer features twin dual exhaust. The taillights feature vents which mimic the outsource of airflow, similar to that of the Ferrari 488 GTB. The spoiler is a low, lean downforce-inducing wing. The headlights are a twin-cluster with a main headlight and an auxiliary tinted light, not including the rally style fog lights.

Compact Drivetrain

The chassis is extremely compact in and of itself. I borrowed the drivetrain design from Builderdude35’s Falcon FAV100. Two Large Motors drive a 36z gear which drives a half-bevel 12z gear (these are encased about an H-frame). It then transfers drive both to the front and rear of the robot. There is a differential which transfers power to the rear wheels, while the front axle extends to the front of the car as a neat auxiliary cue. The rack and pinion steering setup is controlled by a Medium Motor, and stabilized with a LEGO rubber band. Check out the metallic exhaust tubes while you’re at it!
