Re: NXC for NXT and RobotC for EV3 feature comparison

Yes, I'll report back when I try RobotC on the EV3. I expect it will be about a month or more until I finish my current NXT project. Yesterday at Worcester Polytechnic's Touch Tomorrow Festival (a NASA robot challenge and hands-on family science fair), I got some ideas for new robots. And I'll need ...

Re: NXC for NXT and RobotC for EV3 feature comparison

Hi, Thank you for the info. This is interesting and useful. The translating from NXC to RobotC sounds more complicated that I was hoping, or maybe that was just my wishful thinking. Although I would like BT support for more than 1 slave, I currently only have projects with 1 slave. I found that if m...

NXC for NXT and RobotC for EV3 feature comparison

Has anyone done a feature comparison of NXC and RobotC? I've used NXC for over 4 years now and have truly enjoyed creating robots with it, and have thousands and thousands lines of NXC code. I'm starting with the EV3 and find EV3-G painful. I can't imagine myself writing libraries of functions for r...

Re: Question on utility of LEGO robots as a communication tool.

Not an exact answer to your questions, but some ideas that may help. I'm retired and am a reading volunteer in 2nd and 3rd grades. I did read with one child on the Autistic Spectrum. I also build LEGO robots, as a hobby, and take my NXT robots into elementary grade classrooms. They, the robots and I...

Re: line follower with mutex and three sensors, obstacle avoid

The proportional line follower at <http://www.nxtprograms.com/NXT2/line_follower/steps.html> has worked very well for me. This is an NXT-G program but I adapted it to NXC. My program is here <https://sourceforge.net/apps/phpbb/mindboards/viewtopic.php?f=4&t=680>, Kemmel - Combining Line Following an...

Re: Battery consumption

Hi, Not knowing what languages you're familiar, but if you are familiar with 'C', I'd recommend NXC and the books LEGO Mindstorms NXT Power Programming by John Hansen and Creating Cool Mindstorms NXT Robots by Daniele Benedettelli. These two books explain the language well and have good examples. Be...

Re: Robot related books for kids and adults

I've updated my list of robot related books, and other media, for grade school kids and teachers - some minor edits and pointers to sites related to An Hour of Code. Far and away the most favorite books among the kids are: Robots by Clive Gifford (Antheneum Books) Note the publisher, as author has t...

Re: Introductory Guide for EV3 Programming?

I highly recommend the book "The LEGO Mindstorms EV3 Laboratory" by Daniele Benedettelli. I'm about half way through the book and have no complaints. The author covers on board programming very well and then progresses to programming on your laptop or PC in a way I found easy to understand. In chapt...

EV3-G programming block for NXT light sensor

Is there an EV3-G programming block available for the NXT light sensor? I did find programming
blocks for the Educational Set gyro and ultrasonic sensors at LEGO.com. Thanks for any info.

Re: Looking for EV3 Infra Red Sensor and Beacon Specs

Thanks for all the ideas. Regarding distance in beacon mode, I've found that 2 m is about the limit with fresh batteries. And with just one beacon turned on, the robot is pretty good at stopping at about 15 cm away, per my program, give or take a little from run to run. With multiple beacons, even o...
