Dagu Playful Puppy Robot

Hi, i have bought the Dagu Puppy Robot and built it according to instruction manual. But the hip and feet movings doesn't follow the code. Even if i put the command "return;" in the main loop, the servos still move randomly (please check the video clip).

In the video clip i've plugged out all pins except one for test purposes.

Connecting LEDs to the 8 pins and with suitable code the board works fine. Could anyone help me please?

Swarm Robot build

Hey LMRians!

It's been quite a long time that I haven't been here (mostly due to being in the second last year of school and other projects). Recentlly I got interested in robotics again and I came up with the idea of building swarm robots (just a little group of maybe 10 bots, not 40+ that the universities use).

Here I want to describe my thought process a little and then ask some questions.

So my first goal is to make it relatively small, something of the size like the robots seen in this excellent video by the University of Sheffield (see embedded video below).

Integrated Project at college!

i Want to direct a robot,s path using C language !

i have seen your basic robot which uses Sharp infrared system ! It will actually do my work but the problem lies here is that it is based on picaxe. now i wanna know taht if these codes for controlling the robot can be generated in Turbo C. or can these ic's and the servo motors with the programming cable will be able to work with C or do i need to just change everything in the line up accordingly ! m new here so ill be really glad if helped !


i know basic C programming ! also i know nothing about PICAXE !

The Doctor's Robotic Assistant!--THE MEDIBOT!

Hello, LMR!


I've been thinking about my research project for this summer for the Authentic Science Research course that I participate in, and I've had some ideas for what I might be accomplishing.  **NOTE**--this is currently just an idea, so nothing on this is final yet.  When it is, you will know.

Lego Mindstorm C# USB

Hi there,

QUESTION - Grid tracking robot


I am completely new to robot building and, in turn, new to this forum. I am currently studying Computer Science so I may be able to use some of what I know already to help.


Anyway, I have a basic idea in my head but I am asking for a little help on, how you think, it could work. It seems relatively easy in my head - for those that are used to robot building;
