Let's Make Robots!

robot

Got all the parts... any tips before I start?

Hey all, so I have a simple idea for a robot, hack a hexbug spider and put a Sharp IR sensor on it to make it autonomous.

 

I have:

1 hexbug spider

1 Arduino UNO

1 Seeed Studio motor shield

1 Sharo IR sensor from the SH robot

all the hook ups, solder etc.

 

Heres my question; would it make more sense to hack the existing chip on the spider, or cut it out and just have everything go straight into the Arduino? 

 

If you have any tips or such before I get started, that would be really appreciated!

Speech Recognition - Robot Thinking and Understanding

Programming a robot to do a single specific task such as following a line is hard enough for most people. So how do we program a robot so it can perform many different task? How do we command / control it?

Recently I have been wanting to use the speech and voice recognition of an Android mobile phone. My friend Bing wrote a simple app for me that allows my controller to connect to an Android phone via Bluetooth and then send the phone a list of words that I want the robot to recognize. For example: "OddJob,go,forward,backward,turn,stop"

T'REX controller now available from Sparkfun

Good news for anyone wanting to control big motors up to 24V with stall currents as high as 40A. The T'REX robot controller is now available from Sparkfun.

https://www.sparkfun.com/products/12075

The controller is basically an Arduino Nano 328 with a switchmode power supply and high current motor drivers with electronic braking and current monitoring.

T'REX tank chassis

It's been a long time coming but the T'REX robot chassis is here!

I've just been testing the final product so I thought I would post a few photos of the new chassis. The chassis is aluminium with a black powder coating. The tracks and struts are zinc with a black anodized finish. The wheels are zinc with a chrome finish.

UPDATE 08/02/2014 : Just an update in the name. I remember OddBot calling it the BlueTacBeast. There you have it! I present to you BTB aka BlueTacBeast aka a mini … Read more

Mecanum Robot

In my blog about the Shanghai Maker Carnival i wrote about the workshop and our VIP guests but not much about the other stuff. here it goes, the other stuff. One of the interesting objects was the Mecanum Robot (well, actually remote controlled), a project of my colleague Angelo. He build that monster, improved, failed, improved again to make it work. You might imagine how much fun it was to test it in the office :-)

Robotics T-Shirts

UPDATE: Only 2 left!

UPDATE: They are all sold! I look forward to you guys hanging out in these shirts!

I'm running a crowdfunding campaign on a T-Shirt!

This campaign has two purposes:

1. To help with my 3D printer fund

2. To test the TeeSpring system as a potential for LMR branded T-Shirts

The T-Shirt is shown below.

Service Droid V3.0

I was talking to a friend last night and he pointed out the Service Droid would be better on the Rover 5 Chassis. This is what I have so far.

The Service Droid is a cheap robot body with a reasonable amount of functionality. The idea is that you can fit it with whatever sensors and processor you want.

RC Robot Car wheels turn too slowly

I have just put together a basic rc robot car, based on an arduino uno, motor shield (as I fried the original circuit board trying to measure voltages :) and of course a basic rc car (new bright). I can get the car to turn its wheels left and right and get the wheels to go forwards and backwards (when in the air) however the forwards and backward wheel speed is lacklustre (analogwrite(11, 255)- to the point where if place it on then ground the wheels don't turn and the car doesn't move. If I connect the rear wheels to the battery directly (9v battery) the wheels turn ok.

Smart Doodle Bot: ES100 MC Group 3

Hi everyone!

We're wrinting this blog as part of a college project for our ES 100 Introduction to Engineering and Design Class.  This will be the first robot we have ever made.  The purpose of this project is to make a robot that can draw, make music, and dance.  

We're purchasing the "smart doodle bot" from Hobby King to get started.  We put our order in on September 8th.  Hopefully, it will come in soon because we could only purchase it from Hong Kong.

First robot idea

I'm new to this website, but have been researching robots for a while, and my ultimate aim is to have a cube shaped robot on 4 wheels which can walk around on its own, and can follow you, with a talking ability if that's possible, any help would be appreciated. Thanks, smiggle

Working for DAGU means I need to try and design products that are not just cool to look at or play with but are also affordable and easy to use for the beginer. Sadly this balance is not easy to acheive. Usually more fun / cool functions means more complexity and cost.

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.
