To finish, all you need to do is call the “nnect” function to connect with your Sphero. The colorful LED matrix is fully programmable and easy on. The attributes passed in are the following: sphero.roll(speed, heading, state, option) Learn to code by drawing, using Scratch blocks, or writing JavaScript text with the Sphero Edu app. By coding the lights, sounds, and movements of indi, you can create unique mazes, play games, write simple songs, and ultimately learn the basic logic of programming. To make the ball roll, you simply need to call “.roll()” on the sphero, like this: spheroBall.roll(70, 270, 1) With Sphero Edu Jr you can connect to your indi and customize its behavior with simple yet powerful programming blocks. Once you got that working, it’s time to hook up the Sphero and the Leap Motion together. These coordinates are in the format “x,y,z” so horizontal axis, vertical axis and depth. Complete Activities to learn how to program your Sphero robot, dive deep into STEM topics, and lots more. A remastered version, the Sphero 2.0, was launched in August 2013. Their first product, the Sphero, is a white spherical robot launched in December 2011 capable of rolling around under the control of a smartphone or tablet. Create a Sphero Edu account to save all of your work. (formerly Orbotix) is an American consumer robotics and toy company based in Boulder, Colorado. Find out which devices you can use with Sphero Edu here. Compatible with Sphero Edu app for iOS, Android, Amazon Fire OS, macOS, Windows, & Chrome OS. 5V 2.1A USB-A on-board connectivity to power projects using RVR’s battery. Drive your robot or create a unique program. 4-pin UART expansion port to connect to any 3rd-party hardware. Gets you the difference between your first frame and the current frame, so you can see which coordinate is the most impacted by your movement and therefore get the direction. The Sphero Edu app helps bring your robot to life. Once you can track your hand, here is how you track the direction of your movement: ame(1) Then, create an instance of the Leap Motion controller and start slowly by just tracking movement over it. The reference of the Sphero should appear and you just need to copy it in the code (it will probably be the same as mine). To find that, turn your Sphero on as well as the bluetooth on your computer, connect to the Sphero, and once this is done, execute this command in your terminal: ‘ls /dev/tty.Sphero*’. You then need to create an instance of the Sphero by using the reference of the ball on your computer. You start by requiring the modules you need, so here, ‘leapjs’ and ‘sphero’. If I start by explaining the setup of the app in Node.js, here is a snippet of my app.js file with comments to explain what everything does: // require the relevant modules var express = require('express'), path = require('path') //create web server var app = express() //require the custom module var test = require('./my_modules/sphero') test() // Everything in public will be accessible from '/' app.use(express.static(path.join(_dirname, 'public'))) app.use(express.static(path.join(_dirname, 'views'))) app.all('*', function(req, res) When I started working on this project, I used the Spheron module but I think something is not working with it anymore so I changed to the official sphero.js library. If you’d like to go straight to the source code, you can find it on my github. You can follow the project progress on the website, and if you're interested in hacking on it, the code is all open source on github.A few months ago, I wrote a tutorial on how to control the Sphero with the Leap Motion using Cylon.js but I actually forgot to write one about using Node.js (which is what I started with). Check out for brand new activities that will keep you inspired day after day. Simple enough for beginners, yet sophisticated enough for seasoned programmers. The Android app is available for testing from the Google Play Store. Install now Visit Sphero Edu Sphero Edu Your hub to create, contribute and learn with Sphero robots. But the app is already in a state where you can get Sphero to behave if you have a little patience. Detecting the user's motions reliably remains a work in progress (along with making Sphero's motions match smoothly). The constrained context (birds-eye view of Sphero on the ground) makes the vision problem easy (a simple image template match works well), but is still a bit complicated for a first-time user, so I'm working on improved designs to make this as easy as possible.Īfter setup, the phone camera is not used only the sensors are active. The setup portion of the app uses computer vision (via OpenCV) to calculate the mapping between the phone's sensor coordinate system and Sphero's "forward motion" orientation. So I decided to come up with something simpler that would be more fun for anyone (kids or adults) to quickly learn and play with. I had previously come up with another Sphero app, but it was quite complicated both in terms of user experience and implementation.
