ToyCollect: A robot that collects toys from hard-to-reach places

ToyCollect: A robot that collects toys from hard-to-reach places

The people at Seewald Solutions posted about their Raspberry Pi-based robot they call ToyCollect. Inspired by the creator’s daughter, who hides her toys under the couch, the robot is controlled via Android and can be driven under the couch to allow the user to view the hidden toys via a Raspberry Pi camera module and retrieve them. Along with a Raspberry Pi, the ToyCollect robot uses a Zumo Chassis Kit, 100:1 Micro Metal Gearmotors HP, Qik 2sv1 Dual Serial Motor Controller, and a Zumo blade to push the toys. The video below shows the robot in action (in German; subtitles available):

For more information, including the source code and instructions for building your own ToyCollect robot, see the ToyCollect post on the Seewald Solutions website.

Raspberry Pi-controlled chicken coop

Raspberry Pi-controlled chicken coop

Forum user bennard posted about his WiFi-enabled chicken coop, which uses a Raspberry Pi to monitor and log data about its environment, serve a web page, send emails, and open and close the coop door. The system has sensors for detecting temperature, humidity, motion, and light, and includes a 50W solar panel and solar charge controller for recharging its batteries. The automated door is a hinged piece of wood that is connected to a linear actuator (via this mounting bracket) and controlled by a jrk 21v3 motor controller.

Severed fingers Halloween prop

At Halloween parties, it is common to see a punch bowl with one or more eyeballs floating in it and stomach-churning decorations like severed fingers or gelatin worms lining the festive dishes. However, the problem with most of these is that they are motionless and bland. Inspired by Thing, the disembodied hand from The Addams Family, I decided to make a creepy animatronic hand to add some thrill to an otherwise boring table display. Continued…

Candy bowl surprise

Candy bowl surprise

Anyone who has gone trick-or-treating has seen the house that puts a bowl of candy on the front porch and knows that there are those greedy trick-or-treaters who take more candy than they are supposed to. Well, if you are that person who puts the bowl of candy out on your front porch, you can make trick-or-treaters think twice before they take more than one piece of candy. In this project, I actuate a severed arm to slap down at the candy bowl whenever someone goes to reach into it. Continued…

Ascending/descending spider

This animated spider prop takes a traditionally static Halloween display to new heights! The setup is simple: a Maestro servo controller and a continuous rotation servo raise and lower a spider with the help of a limit switch. Continued…

Scary shaking tombstone

Scary shaking tombstone

Before we started our Halloween projects, several of the Pololu engineers took a trip to a local Halloween store to get inspired. At the store there was a wall lined with the polystyrene foam tombstones that are meant to be stuck into your front lawn. They immediately made me think of the graveyard outside the haunted mansion at Disneyland, and I knew that I wanted to make one of them shake and scream. For added effect, I also picked one that had a few skulls on it, so I could place red LEDs in the eyes. Below are some of the details that went into making the project so far. Continued…

Inflatable ghost

Inflatable ghost

After doing the creepy mask, I wanted to do something a bit more festive. This Halloween prop was inspired by those inflated decorations people put on their lawns. In this case, I wanted something a bit smaller since I wanted it to fit indoors. I also wanted to use one of our addressable 8mm RGB LEDs, so I could make it light up all sorts of colors instead of just a single color like I had often seen. I decided to make an inflatable ghost because I wasn’t sure I would be able to control the shape that well and figured a ghost would give me more leeway in shape. Continued…

Simple Animatronic Skull

If you have been following our blog, you have seen some fun and scary Halloween projects posted by my coworkers here at Pololu. Well, this is the first part of my prop for my costume for this upcoming Halloween. After watching an animatronic devil baby terrorize New York City, I knew I wanted to build a similar demon baby that would be attached to me with a baby carrier. Continued…

Ghastly gas ghost

Ghastly gas ghost

This project turns a innocent-looking ghost decoration into an ambush in wait for unsuspecting passersby. The basic idea is straightforward: whenever someone walks within a few feet of the ghost’s face, it blasts them with a terrifying burst of compressed gas. Continued…
