The display was prototyped on a huge breadboard assembly, along with an Arduino Mega, then finished using a custom PCB and Arduino Nano.
3D-printed parts are used to form the housing, in addition to a variety of electronics. These include an actual GPS unit, along with a custom three-segment LED assemblies to display “+” and “-” as needed.
Be sure to check it out in the video seen here, showing off its interface, as well as an MP3 unit that plays back a 1962 JFK speech about going to the moon.
If you’re tired of classic tower building games like Jenga or stacking cards and would like a new challenge, “mr_fid” has come up with a game where you balance blocks on a tree assembly. The nicely crafted device then moves around to throw the blocks off using three servos and push rods.
Everything is controlled by an Arduino Nano that randomly selects the intensity of the movement and which color of block to be stacked, displayed on a circular arrangement of programmable LEDs.
Once a block has been added, a button in the middle of the LEDs is pushed and tree movement starts, potentially destabilizing the player’s work.
Nice Arduino project. Featuring an Arduino Nano controlling 3 servos to move the tree. Firstly the “Roll” button is pressed to give you a colour and amplitude once the correct bit has been placed on the tree the “Shake” button is pressed and the tree moves around. Any bits which fall off are given to the person whos go it was! the idea of the game is to get rid of all your bits first. If when you press the “Roll” button you don’t have the correct colour OR the strength is to high then if you wish you can miss your go.
You can check the game out in the first video below, or see the second video for information on how to avoid jittery servos in this type of setup.
Up until the present day, if you need butter, you simply ask another human to “pass the butter,” leading to minor inconvenience and awkwardness. Engineering students in Brussels have come up with a novel solution: a robot that brings the butter to you!
The robot, inspired by Rick and Morty’s Butter Bot, is powered by an Arduino Uno and summoned to hungry humans via an infrared remote control.
When the signal detected by onboard IR sensors, the robot moves over using continuous-rotation modded servos, then flips its cap-like lid to reveal the butter inside.
To give it decent range and reliability, the hacker turned to a stock transmitter and receiver, but routed the PWM signals onboard to a Mega. The Arduino uses a pair of H-bridge boards to drive all six motors/wheels for tank-like movement.
Since an Arduino is used, this opens up a wide range of manual and automatic control options, and could even be used to power robotic accessories like a gripper or gimbal with a camera.
I decided to build a bigger robot that will easily overcome various obstacles on its way and will be able to move with a load of at least a dozen kilos. I also assumed that the robot should be able to cope in difficult terrain such as sand, snow and rubble. To make it possible, I built a 6-wheel [aluminum and duralumin] chassis equipped with 6 motors of sufficient high power and suitable motor driver and power supply. I also wanted my robot to be controlled from a long distance (at least 200 meters) so I used a good quality 2.4GHz transmitter and receiver.
You can see it in action below, traversing through a forest near Warsaw, Poland.
This is accomplished by a series of three servos that transmit force through cables for the index finger, middle finger, and thumb. Control is via an Arduino Uno, which takes input from pressure sensors in the three finger fixtures, helping the wearer keep gripping when force is initially exerted to close a fist.
The glove has a wire connection that links the fingers to some servo motors: a wire is attached to the extremity of the finger and to the servo, so when the servo turns, the wire is pulled and the finger is flexed. In this way, by controlling the grip done by the user through some pressure sensors in the extremity of the fingers, we are able to actuate the motors in a controlled way and help the gripping by bending the finger proportionally to the rotation of the motors and so to the rolling up of the wires. In this way we should be able either to allow weak people to grip objects or help even people in physiological conditions to grip objects and to keep it without any effort.
While still a prototype, it’s an interesting device that could be developed further into a very helpful augmentation. You can see it in action below!
