SharkBot – Robotic Shark

The SharkBot robot is built with Lego Mindstorms Ev3 and is basically a modified version of Builderdude35’s Timmyton 5.5 robotic shark. It features aerodynamic styling, mechanical upgrades, modified programming, and more (including both autonomous behavior and remote control function).  Continue reading

Rally Rac3r series

After a bit of an absence, I am back with a technically failed project. Rally Rac3r was built to be very fast with its 9:1 gear ratio, but the resulting low torque prevented reaching top speed in little time. It features exhaust pipes, opening gulling doors, rally-worthy lights along with accessory roof lights, rear spoiler, return to center steering with gear rack, smooth flowing aerodynamics, and more.  Continue reading

Sup3r Stadium Truck | Short Course

This is a large short-course style stadium truck built with Lego Mindstorms Ev3. It features independent rear suspension and a front live axle with steering. One Medium Motor controls the steering, and one Large Motor drives the rear wheels. It also uses the InfraRed Sensor for Remote Control.

The reasons I used only one motor in this model are: 1. I was attempting to reduce weight, 2. The chassis of the truck is even studs wide, not odd; not allowing a very easy placement of two motors, 3. This vehicle was built as a test vehicle for the new 4-stud wide differential I got a while back but never used until now.

The drawbacks of this truck are: 1. One motor does not exert nearly enough power, 2. The old-type differential makes it impossible to not use more gears in order to transfer the power, 3. All the gears used decreases efficiency massively, 4. The rear independent suspension worsens performance, 5. A 3:5 gear ratio was used (a 1:3 would have been better), 6. The truck is very large, bulky, and heavier than most other robots that I have built.  Continue reading

Blast3r Droid (mySENTIN3L)

This is Daniele Benedettelli’s SENTIN3L…in an extensively upgraded form! I programmed an entirely new program for Blast3rDroid (mySENTIN3L) that enables Remote-Control of the robot! This robot is about 22% quicker than the original! The RC program has two channel modes: Channel 1 for regular usage, and Channel 2 for upgraded usage modified for quicker speed and more accurate turning! The color scheme has been revamped, featuring a lot of bold coloring (most of the black has been replaced with red and white). I added more panels and wider panels for improved aesthetic appearance. The COLOR CUB3 has been revised and now has four colors: black, red, white, and yellow.  Continue reading

SENTIN3L | Model Review

This is an unofficial review of Daniele Benedettelli’s SENTIN3L from his book THE LEGO® MINDSTORMS® EV3 LABORATORY. It serves as a guard/patrol type robot and features 2 Large Motors, 1 Medium Motor, 1 Color Sensor, 1 InfraRed Sensor, and 1 Touch Sensor. These function for synchronized front legs, synchronized laser arms for blasting/shooting, autonomous behavior, color-programming, and more. Also featuring the COLOR CUB3!  Continue reading
