PIDDYBOT: DIY Arduino Balancing Robot

Sean Hodgins designed this open source balancing robot to help teach PID control:

The PIDDYBOT

The PIDDYBOT is currently using a Atmega32u4 microncontroller. It uses 3 potentiometers that allow you to manually tune the PID loop to get the robot balancing. This allows you to see how each term affects the performance of the system. It is a great teaching tool for the classroom and is currently being used by students at McMaster University.
The design files and source code is available on GitHub:

Mr. Runner

The aim of this project is to lower the barrier of entry into dynamic robotics. After seeing Boston Dynamic’s Wildcat I became interested in working on something similar, but was disappointed with what the hobbiest scene had to offer. They all used static locomotion. I wanted it to feel alive!

I hope that if people can see that this style of robotics is reproducible with basic development skills, it will attract a wider range of people to legged robots than just those who want to see a vaguely spider looking device re-implement the same kinematic equations over and over again.

The approach is based on the work of Fumiya Iida and Rolf Pfiefer at the University of Zurich in the mid 2000’s. Dr. Pfeifer is well known in the field of embodied cognitive science, and these experiments were an attempt to generate movement in quadruped robots based on those principles.

DIY 6-Axis Micro Manipulator

[David Brown]’s entry for The Hackaday Prize is a design for a tool that normally exists only as an expensive piece of industrial equipment; out of the reach of normal experimenters, in other words. That tool is a 6-axis micro manipulator and is essentially a small robotic actuator that is capable of very small, very precise movements.…

Robotic Arts: Noodle is Gettin’ Bean Feet

Sarah Petkus posts an update on her Robotic Arts blog about her NoodleFeet robot:

Noodle is Gettin’ Bean Feet!

This summer, I am once again diving into designing mechanical personality quirks. I’ll be investigating new and exciting ways for my robot, NoodleFeet to interact with the world. This time, my focus is the wet, tingly and preferential aspect of TASTE.

moduledrawings

From now until the end of August, my goal is to produce four different tasting modules that each demonstrate some aspect of sampling or preference. You could think of them as the “four tasters of the apocalypse”

If you’re unfamiliar with Sarah and NoodleFeet, then check out here great talk from Hackaday Super Con:

Bristlebot with LDRs Becomes Light-Following Bristlebot

Bristlebot with LDRs Becomes Light-Following Bristlebot

Bristlebots are great because no coding is required – they’re completely analog circuits that just go! But if you wanted them to go in a specific direction, how would you do that? Facelesstech has released their design for a light-following bristlebot that uses two LDRs to drive either side of the bristlebot (so you could turn it, somewhat – see video below for demo!). It’s pretty simple and pretty clever.

Chicago Robotics Corp is exploring 3D Printed Robotics with Simula:

simulated life-forms for use in research and entertainment

The robot is programmed with Arduino IDE:

You might choose to program Simula by yourself from scratch, modify our existing software, or just keep up with our latest simulations.

Arduino Library for the Simula Boards and Modules is on GitHub:

BoosterBot for TI LaunchPad

BoosterBot turns a TI Launchpad into a fully functional robot:

Screenshot at 2016-10-27 00-26-48.png

Perfect for anyone who wants to get started with MSP430 and robotics, or just wants an easy to use robotics platform to build off of.

The board features:

  • Micro Metal Gearmotors from Pololu
  • Powered by 3xAAA batteries
  • Five QRE1113 Reflectance sensors for line following and maze solving
  • Header for a Sharp IR distance sensor
  • Header for a servo

The design files and source code are available on GitHub:
