Interesting drawing Robot, Makelangelo (Drawbot)

Posted on December 30, 2014 by robertwilkie

I stumbled on this looking for something else.  Its an interesting design, and doesn’t look too hard to make.  Just wish the design was a bit more “open”. https://www.marginallyclever.com/blog/drawbot/ https://www.marginallyclever.com/shop/drawing-robots/ https://github.com/MarginallyClever/Makelangelo   Update: I might have found an opensource one…stay … Continue reading →

Build your own Stepper Motor driver

Posted on November 24, 2014 by robertwilkie

Interesting build, If I total it all up…I could still by a driver cheaper  :).  But could be a good learning experience. http://www.instructables.com/id/CDDVD-Bipolar-Motor-Driver-Wo-Microcontroller/

Another simple robot arm

Posted on November 18, 2014 by robertwilkie

This arm is 3D printed instead of cut like the previous.  The directions are not as good as the last one, but its still a nice build and uses an arduino. http://www.instructables.com/id/Arduino-Robotic-Arm-1/

A cheap Robot Arm

Posted on November 18, 2014 by robertwilkie

Nice simple build with a couple of servos and a small sheet of plastic.  I wish there was an outsourced order group to get the “cuts” done thought referenced in the directions. http://www.instructables.com/id/Pocket-Sized-Robot-Arm-meArm-V04/ And bigger one here: http://www.instructables.com/id/My-meArm-Bigger-Stronger-Longer/ UPDATE: there … Continue reading →

Crack a padlock automatically

Posted on November 13, 2014 by robertwilkie

Nice build (and write-up on how to figure out the combo)  of a padlock. I like the fact they did a little tinkering to figure out how to solve the lock quicker without straight brute force.  If you got a … Continue reading →

Build a robotic bartender on the cheap

Posted on November 12, 2014 by robertwilkie

Well cheaper than the aiBAR mentioned.  Nice build though a bit clunky.  Clean up the wood box would go a long ways. Oh and non-plastic cups. http://www.instructables.com/id/Robotic-Bartender-Arduino-Based/

Build your own vac based robot gripper

Posted on November 5, 2014 by robertwilkie

A simple write-up using a vacuum, funnel, balloon, coffee, and a small bit of cloth to make a gripper for a robot.  My 2 cents, make sure you use a strong balloon for this project.  Not one of the cheap … Continue reading →

Build your own Arduino based, one arm, drawing bot

Posted on November 4, 2014 by robertwilkie

What is nice about this build, is not only using an arduino, but servos for the motors too.  Its a pretty simple build and could easily be done with kids.  I wish the write-up was a bit better thought. http://www.instructables.com/id/Drawing-Robot/

Vaccum Grip out, Electrostatic in

Posted on October 31, 2014 by robertwilkie

It seems a new wave of grippers for robots is out, and its using electrostatic to wrap around an object to grip it.  Clever idea and looks like it works pretty good. http://spectrum.ieee.org/automaton/robotics/robotics-hardware/electrostatic-robot-grippers?utm_source=feedburner-robotics&utm_medium=feed&utm_campaign=Feed%3A+IeeeSpectrumRobotics+%28IEEE+Spectrum%3A+Robotics%29

A brushless motor controller for arduino (shield)

Posted on October 13, 2014 by robertwilkie

The author build and published the PCB design for a brushless motor controller for arduino.  This could be useful for higher end brushless motors found in R/C cars…or maybe robotics too. http://hackaday.com/2014/10/08/brushless-motor-controller-shield-for-arduino/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+hackaday%2FLgoM+%28Hack+a+Day%29 https://github.com/Neuromancer2701/BLDC_ros_controller
