Haptic Controlled Robot Hand

This project brings together the DIY Haptic Control Glove and the Robotic Hand that I made earlier. The cost of this entire project was less than 25 US$. For details on how they were built and how they work, just follow the link for each.

This video demostrates the complete project.

1. Calibration of the glove
2. Control of the fingers
3. Touching finger tips of little and index fingers to demonstrate
thumb movement
4. Performing a simple task
5. Detail of servo movements

Belay That Photon Torpedo Order!!!

This post is about the application of Conditional Probability and Bayes Theorem in target detection by a randomly maneouvering search platform. Most tutorials about Bayes Theorem on the internet deal with issues like cancer detection maths or picking coloured balls from a hat. I needed a little bit more realism in my quest to understand Bayes Theorem and so I devised the following scenario.

It has taken my small brain months, maybe even years to begin to comprehend Bayes Theorem so don’t be disheartened if you can’t understand this post right away. Keep at it, keep reading, and like me, one day, the truth about our beliefs and the way we form them will dawn on you!!

I have chosen to write this post as a work of fiction rather than a paper on the subject it really addresses. In a nutshell —> Just because your sensor has reported a target detection, it doesn’t mean that there is actually a target there. Continue reading

Starting Robotics: Haptic Controlled Robotic Claw

Now that my 6 DOF robot arm is assembled and tested, I thought it would be
nice to get working on the first technique I need to understand: haptic control.

Haptic : Of or relating to the sense of touch; tactile. [Greek haptikos, from haptesthai, to grasp, touch.]

The basics of haptic control:-

1. Sense the movements of the human body
2. quantify these movements into electrical signals
3. control robotics with the electrical impulses
