Let's Make Robots!

Trick switch not working.

I built a trick switch using  Make's basic Arduino Projects bookelt the other day, and I'm running into a problem.

Book Recommendation: "The Peripheral" by William Gibson

I dl'd the eBook version of this to read while recovering from surgery last week and could barely put down the iPad.  It adds makers to the list of hackers that Gibson has been writing his tributes to for the last several years.  I was surprised by how much the idea of 3D printing could become a part of the fabric of a story and have it remain interesting.

Options For a Remote Control T'REX

Dagu's T'REX robot controller has several options for operating the board with a remote control device of some sort.

The program which comes with the T'REX can accept several different remote inputs. These include (but not limited to) Bluetooth and pulse length signals from a RC receiver.

Large robot chassis with 50W MP3 player

Dagu is now selling the chassis for our Venus robot as a separate product for $435 USD.
Please note there is a discount for people who log in and an additional discount for LMR members.

This is an ideal chassis for anyone who wants to make a large butler robot. It is an aluminium chassis with 2x 200mm (8 inch) drive wheels with rubber tires plus 4x caster wheels for stability.

Books, Lots of Books

Hi,

I'm unpacking boxes and replacing the stuff that I'll be keeping from the divorce. That leaves a lot of stuff to get rid of. I have a lot of robotics books that I'll be putting up on the Marketplace.

My question is that I have a ton (or maybe two) of science fiction/fantasy/mystery books. Do you think they would sell here, or should I put them up on EBay?

Many of these are old and aren't available as an ebook yet.

Trex Motor Controller i2c read while using rc

I am starting to put together a rover using Wiild Thumper and the TRex motor controller.

I am having some difficulties getting i2c working reliably from a Raspberry Pi 2 running Ubuntu 14.04

While I am continuing to research my issues (possible future post coming) I decided to give the RC connection a try.

My question is if it is possible to access the i2c read only while using the RC as I would like to try out code for monitoring the current draw and battery voltage.

Record PWM values over time, tweak graph, playback to robot possible?

Hi All,

I'm trying to find the best way for me to drive an RC car around, have either the transmitter or car send the PWM values its using back to a computer which will record it over time.  I then want to tweak the graph, and then play it back, and have the computer send the RC car the new "tweaked" PWM data and it will then drive around by itself.

Can't connect to Mini Driver board

I recently purchased a Standard Educational Tadpole. This little kit for beginners comes with a Dagu Arduino Mini Driver Board. Here is the link: https://sites.google.com/a/rocketbrandstudios.com/rocket-brand-studios/store/tadpoles/tadpole-educational Tutorial for it: https://sites.google.com/a/rocketbrands ... main-minid Anyway, I have the pins and everything in the correct place, but the board itself is giving me problems. I've installed the driver over and over again (at least 5 times) to no avail. It has a blinking blue light that comes on, and a red light.

Of course there are robots as well, but they don't feature as heavily-or, depending on how you look at things (was

Program freezing (or getting stuck?) when asked to calculate large numbers

Hi Guys! Ive done buckets of trouble shooting on this, and i THINK i have identified where the problem is, but i cannt work out how to correct it. In short i am programming my CNC router (converting GCode into CNC movements)
