A Robotic Elevator using Lego & Arduino – Part 4

A Robotic Elevator using Lego & Arduino – Part 4

Part 1: Mechanical Design Basics. Part 2: Balancing the Elevator. Part 3: Electronics (optocoupler, H-Bridge, and more). Part 4 (current): Software to control the Arduino. In this last part, we will be describing the Arduino software that controls our Lego elevator. But, let’s first define the desired behavior. As we have described in the part […]

A Robotic Elevator using Lego & Arduino – Part 3

A Robotic Elevator using Lego & Arduino – Part 3

Part 1: Mechanical Design Basics. Part 2: Balancing the Elevator. Part 3 (current): Electronics (optocoupler, H-Bridge, and more). Part 4: Software to control the Arduino. In the first two parts of this series, we have introduced the mechanics of our Lego-based elevator and we discussed how to balance it to lift some load. Today, we […]

A Robotic Elevator using Lego & Arduino – Part2

Part 1: Mechanical Design Basics. Part 2 (current): Balancing the Elevator. Part 3: Electronics (optocoupler, H-Bridge, and more). Part 4: Software to control the Arduino. In the first part of this series, we introduced the core structure of our elevator. But, we aren’t done yet with the mechanics. As shown in Video 1, our initial […]

A Robotic Elevator using Lego & Arduino – Part1

A Robotic Elevator using Lego & Arduino – Part1

Part 1 (current): Mechanical Design Basics. Part 2: Balancing the Elevator. Part 3: Electronics (optocoupler, H-Bridge, and more) Part 4: Software to control the Arduino Recently, we scavenged an old Lego Mindstorms 1.5 set. It’s fully functional, but the RCX 1.5 Lego software is obsolete and does not run on recent Operating Systems. Besides, the […]
