A teaching experiment

Today in the robotics class I wanted to try an experiment. We have covered lots of stuff over the past few months, but not so much programming. In these next few weeks we will be concentrating on programming until we get some sweet kits, more news on that later. 

I have been trying to think up cool and interesting ways that the kids can learn programming whilst getting their hands dirty. It's hard to install software on the school computers so we don't have the IDE up and running yet, but I'm working with the IT admin on that. 

T'REX robot controller

 

The T'REX robot controller makes controlling robots easy!

The Arduino compatible controller comes pre-programmed with sample code that lets you control it with a supplied Android app, Radio Control or with an external controller via I²C.

Specifications:

Roam around, play sounds, make noises, be controlled with a SNES controller

JME Mantzel's robot kit on Kickstarter

Hi everybody!

Just have seen JME Mantzel's robot on Kickstarter. I think it is awesome! :) Here is a related video from his channel on Youtube. Also if you like it, spread the word, as what he's doing is absolutely brilliant! :) I'm totally gettting one to play with as it is hack friendly! :)

Hope this type of ad/spam is acceptable :) Actually I hope to see more great things to take off!

Cheers.

[SOLVED] Strange compilation error

Hi everybody!

I'm making a little robot using Arduino and it works fine (you can see how it works on the embedded video).

The robot walk alone perfectly but today I tried to use an infrared remote with an infrared receptor to use my robot like an RC car, and I had this error at compilation (I'm using IRremote library):

 

core.a(Tone.cpp.o): In function `__vector_7':

D:\Program Files\Arduino\hardware\arduino\cores\arduino/Tone.cpp:535: multiple definition of `__vector_7'

Base for paintball rc robot

Hi! This is my first blogpost here, so bare with me.

This will not be the first robot I build, even though I think it could be done by scavaging parts from different finished products. I'm thinking of building an rc paintball car with a camera on it for navigation. Would something like this be useable? http://www.hobbytron.com/HobbyEnginePremiumLabelConstructionCraneTruck11824GhzRTRRC.html#

The girls are cute but they are still less life-like than the automatons. At least you can tell that these really are robots and not costumes.

Sneak preview of T'REX robot tank chassis prototype

 

Inspired by the Rip Saw tank, I have designed a new robot chassis called the T'REX tank chassis. I finally received all the parts for the prototype chassis. The entire chassis including gearboxes and tracks are all metal. The tracks have been anodized a gun metal grey colour.

As I discovered "Bob" I had purple filament in my office 3D printer. Well, i thought it would not make it to the robot section since I am not having enough time to … Read more

Guangzhou Science Center robot competition

As an advisor to the Guangzhou Science Center I occasionally have to go there and do some work. This time I was one of their judges for a local robot competition. There were 2 categories, non-programmable robots for younger students and programmable robots for older students. All teams received a sheet of 2mm thick heavy duty cardboard for their chassis and a kit from DAGU that included:

PID line following

The line following using pid is better. but m unable to understand the procedure to do it on Pic 16 microcontroller...

Advanced Robot Arm Project

This is a long term project to develop a robotic arm that is more advanced that traditional hobbyist arms using RC servos without being so expensive that only well funded universities can afford it. 

The first prototype gripper used standard RC servos while we experimented with the configuration as shown in the first video. Once I had a good gripper configuration I built a prototype arm for it as shown in the second video. This arm used a differential drive system with the goal being to keep the weight of the motors as close to the shoulder as possible.

Robot kits in education

As some of you may know I have been teaching high school kids robotics (well so far programming) for several weeks now, seen here: http://letsmakerobots.com/node/36394.

Beginnings

 

May 19, 2013

I am building a robot controller board using a Zilog Z-80 processor.  For those who don't know, the Z-80 was one of two major CPU chips in the late 70s and early 80s, before the IBM PC ruined ruled the world. The other was the 6502.  I hope you will follow along as the project progresses.  It will be fun.  Why on earth would I want to do such a thing?  Glad you asked.
