Giving RaSPy some personality

Tag, I'm it? OK, here's a quick version that I whipped up this morning. Keep in mind that Jim and I have never seen each other or even spoken on the phone, and there's nothing up my sleeves ;-). The new program has a number of requested features: it will wait until you press and release the touch sensor, and then count out loud "one, two, three" while moving the three arms forward 45° and then back (it also displays the number in a cartoon-like "speech bubble" on the LCD screen, just for fun). Then it picks a number and moves just that motor forward 70° to show which one (rock, scissors, or paper) that it picked. This time I did away with the multi-case Switch block at the end, instead just wiring the random number into a Motor block to directly select which motor to run. It waits for a second press and release (a "bump"), resets the motor that it previsouly moved, and starts all over again.

Notice that it's now up to Jim to test this program on his hardware, and perhaps make some modifications. For instance, I might have the motors running in the wrong direction, in which case he has to go in and switch the direction on all of the Motor blocks. Or he might want the arms to move faster or slower than I've set them. All of this is accessible to him, so he can play with it and custom fit it as much as he wants.

ROBOTMAK3RS Review: LEGO River Steamboat

I thought the LEGO River Steamboat would be an interesting set for a ROBOTMAK3R review for a few reasons. First, the LEGO designer of the model is Marina Stampoli, a long-time collaborator of the late ROBOTMAK3R Vassilis Chryssanthakopoulo s. From earlier collaborations with Vassilis, I knew Marina was incredibly talented, with an eye for aesthetics and functionality. Her background in architecture is particularly useful for her relatively new position at LEGO. Her other sets include the Magic of Disney (21352), Message Board (41839), and Red London Telephone Box (21347). Second, watching Marina's reveal video and reading her designer interview made this set even more tempting to build. The gearing mechanisms running through the model gave way to many opportunities for automation using LEGO robotics elements. Since ROBOTMAK3RS is all about adding interactivity and automation to LEGO brick, I thought it would be fun to see where and how LEGO robotics could be added to this s...

Celebrating 25 Years of MINDSTORMS

In celebration of the 25th Anniversary of MINDSTORMS, we take a trip through history. Please also visit ROBOTMAK3RS Community every week as we highlight different projects all through 2023 in celebration of the anniversary. Some of the early history is based on the content shared by Coder Shah in our MINDSTORMS EV3 Community Group . Some of the text and links may have been edited from his original posts for consistency and clarity. 1984 - Kjeld Kirk Kristiansen watched a TV program called "Talking Turtle," where MIT professor Seymour Papert demonstrated how children could control robot "turtles" using LOGO, a programming language he developed. 1988 - The collaboration between MIT and LEGO resulted in LEGO TC Logo in 1988, which allowed students to control LEGO models using computer commands. The video shows Papert demonstrating TC Logo. 1990 - LEGO TC Logo was hampered since the robots you built had to be tethered to a personal computer. LEGO and MIT...

Ghostbusters R.T.V Remix

Nino Guba is from Torrance, California, USA. He played with LEGO as a kid, but growing up in the Philippines, it wasn’t something he had easy access to. He only got reintroduced to LEGO when he moved to the US and had kids of his own. When his sons were younger, they received LEGO sets as gifts, but as they grew older, the sets got put into storage as their interest faded. Fast forward a few years, he started coming up with his own product ideas and thought about how he could quickly prototype them. That’s when he discovered LEGO MINDSTORMS—and was hooked! He raided his kids’ old collection, got everything organized, and now he's designing and building his own creations, blending his coding skills with LEGO robotics to bring ideas to life. Tell us about your Ghostbusters Remote Trap Vehicle (R.T.V) project. This project is a LEGO Technic adaptation of the Ghostbusters R.T.V.—a ghost trap converted into a remote-controlled vehicle. Its companion build is a prop replica of the Futaba...
