Robot Servo Tutorial with DJ Sures
DJ Sures demonstrates how to connect a standard servo to the EZ-B Robot Controller. He then controls the servo with a joystick, and voice recognition. At the end of the video is a surprise appearance by his hacked Wall-e robot :)
EZ-BoxBot Tutorial Step 1
So, you want to build your dream EZ-Robot... But you don't know where to start? This tutorial will help you build an inexpensive robot to familiarize yourself with the basics of the EZ-Robot Complete Kit. Follow this series of EZ-Robot Tutorial videos to build an inexpensive EZ-Robot with house hold items. In this series we will build an EZ-Boxbot. He'll listen to voice commands, chase a red ball, follow your face, dance, and more! To get started, you will need - An EZ-Robot Complete Kit - 6 AA Fresh Batteries - A Bluetooth enabled computer, or a Bluetooth USB Dongle - Small tissue box - Craft Hot Glue gun and glue sticks, can be found at Walmart. I use the Low Temp version - Scissors or utility knife - Small Philips screw driver - Some crafts to customize the box - 2 Ping Pong Balls - If you wish to remote control your robot, a USB Joystick or Nintendo Wii controller will come in handy Let's customize your EZ-BoxBot before we add parts from the EZ-Robot Complete Kit. *NOTE: Ensure you have followed the previous tutorial steps prior to following this tutorial. Visit our tutorial website to begin: http://www.ez-robot.com/Tutorials Movement Servos ------------------------ 1) In your EZ-Robot Complete Kit, remove the two servos marked DGS. 2) These are the continuous rotation servos that we will use for the wheels. 3) We will cut holes to fit the servos into the left and right front bottom of your robot shell. 4) Mark the size of the servos on the robot to know where to cut. 5) Use your scissors or utility knife to cut a hole for the servos. 6) Test the servo in the hole. 7) Now do the same for the other front side. 8) Apply hot glue on the shell to hold the servos in place within the holes. 9) You should now have two continuous rotation servos mounted to move your robot. Arm Servos ---------------- 1) Remove any two standard servos marked EZ-Robot from your EZ-Robot Complete Kit. 2) We will mount these two servos centered on each side for the arms of the robot. 3) Mark the area and cut like we did with the two continuous rotation servos. 4) Glue the two arm servos onto the robot. Head Assembly --------------------- 1) Remove the two remaining standard EZ-Robot servos from your EZ-Robot Complete Kit. 2) We will use these two servos for the robot head. 3) They will mount on top of the robot. 4) The vertical servo will be centered on the top of the robot. 5) Mark around the centered servo to cut. 6) Because this servo will be moved, we need to extend the size of the hole. 7) You may need to trim this hole even larger once we test fit the servos. 8) Cut the hole for the servo. 9) Test fit the servos and trim the hole larger if needed. 1) In your EZ-Robot Complete Kit, remove the servo attachments and one black screw from one of the baggies. 11) Keep only the one screw and 4 sided servo attachment. 12) Mark the position of the horizontal servo, and cut a small hole for the wire to go through the box. 13) Attach the 4 sided servo attachment to the servo with the black screw. 14) In your EZ-Robot Complete Kit, locate another Black Screw and the 6 sided servo attachment. 15) Attach the 6 sided servo attachment to the other head servo. 16) Mount the 4 sided servo attachment centered to the side of the vertical servo with your hot glue gun. 17) Ensure the servos are attached center and flat. 18) Return to your EZ-Robot Complete Kit and remove the EZ-Robot Camera 19) Using a small Philips screw driver, remove the 4 screws from the EZ-Robot camera mounting bracket 20) Store the screws and mounting bracket in the EZ-Robot Complete Kit box for later use 21) Use the hot glue gun to attach the servo centered to the bottom of EZ-Robot Camera 22) Push the servo wires through the holes in the robot shell. 23) Test fit the servo and camera assembly on the top of your robot. 24) Ensure the servo can freely rotate without touching your robot shell. 25) Attach the camera assembly to the top of your robot with the hot glue gun. Eyes ------- 1) For the eyes of my EZ-BoxBot, I found LED light balls from Walmart. 2) Be creative with the eyes of your robot. 3) You can even use ping pong balls. 4) Attach the eyes to the top of the camera assembly with your hot glue gun. Attach Wheels -------------------- 1) From your EZ-Robot Complete Kit, remove the two wheels. 2) Attach the two wheels to the lower continuous rotation servos. 3) From your EZ-Robot Complete Kit, remove two flat servo attachments Attach Arms ----------------- 1) I am using painted tissue paper rolls for the robot arms. 2) Glue the flat servo attachments to the tissue paper roll with your hot glue gun. 3) Attach the arms to your robot. Remember, the servo has been center calibrated so insert the arms in a position like demonstrated in the video. There, your first Ez-Robot! Follow the next tutorial video and learn how to bring your EZ-Robot to life! :)
The REAL Wall-E Robot
Visit http://www.ez-robot.com/Robots for more of my robots :) This is the a robot built by DJ Sures using the EZ-B Robot Controller and the EZ-Builder Robot Control Software. Visit www.ez-robot.com for more information on how to build your own Wall-E :D The original toy was a U-Command Wall-e that was modified. The tracks are driven by two modified servos. The arms, neck and head are controlled by standard servos. The camera is a 2.4ghz wireless camera. I put this all together with a hot glue gun, a dremel and a lot of inspiration from a great movie. My video does not due this Wall-E robot justice, his personality is far more interactive and humorous in real life. I may make a longer video another day :) ... He is definitely the star of the show!
Connect L298N Motor Driver HBridge to EZ-B Robot Controller
In this video, DJ Sures demonstrates how to connect the 2.5 Amp L298N Motor Driver (sold on www.ez-robot.com) to the EZ-B Robot Controller. When purchasing from EZ-Robot, the motor driver includes the necessary cables for an EZ-B Connection. This process will require you to have a Soldering Iron, Wire Cutters, Lead Free Solder, Small Flathead Screwdriver, and the EZ-B Hardware. The first four signal wires are connected to the Input pins on the L298. The four signal wires should be configured with a 4-Wire HBridge Control within EZ-Builder. The fifth signal wire is connected to the two Enable pins on the L298. The enable pin signal wire port should be configured as a PWM Control.
