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 ReplicaContinue reading


POW3R FUNCTION Grand Prix Racer

POW3R FUNCTION Grand Prix Racer isn’t really a robot; it’s more of an experimental project. The LEGO® Technic Grand Prix Racer set came with instructions showing how motorize the race car’s opening engine cover + spoiler with Power Functions. Well, since I don’t have Power Functions, I thought, “Why not motorize with my EV3?” And that is just what I did. Instead of the PF Medium Motor, I put an EV3 Medium Motor in its place. Now I can open the engine cover and adjust the spoiler very quickly! I hope you like it, and I am soon to come out with a full-blown EV3ized Grand Prix Racer that’s Remote-Controllable in the near future!


SUP3R PICKUP is better than EV3R before! It’s thrice as fast with the rear gear ratio of 9:1! It’s drives roughly 5½ mph. The LDD file of the steering mechanism and two videos of the vehicle in action are available here: Enjoy!


Another SUP3R vehicle: SUP3R PICKUP! As you can probably guess by the name, SUP3R PICKUP is a pickup truck. I made every effort to build SUP3R PICKUP to look like a truck in every aspect. I reverted back to the smaller tires included in the EV3 set. The video and LDD file on the steering mechanism is available here:



SUP3ROD is back, and it’s 3x as fast! The secret? A new 3:1 rear gear ratio! For all the main information, check out the original SUP3ROD. An LDD file of the steering mechanism is available here:


SUP3ROD is a car based on my previous robot, SUP3R JEEP. This is not SUP3R JEEP II for three reasons. Reason #1: It doesn’t look like SUP3R JEEP anymore. Reason #2: It doesn’t look like a Jeep (anymore). Reason #3: It is totally different from SUP3R JEEP! SUP3ROD sort of looks like a buggy, but not quite. I had no idea but to call it SUP3ROD (Super-Hot-Rod). Not a bad name, by the way. OK, back to the subject! SUP3ROD has been extensively modified for days (and midnights!) until I truly liked the result. It is fully drivable, remote-controllable, and steerable! So here is SUP3ROD!
