Fresh hacks every day
This OWI robot arm has been hacked to add position sensors and Arduino control. [Chris Anderson] took one look at the Launchpad controlled OWI from earlier today and said "wait a minute, I've already posted my own version of that project". Well, that will teach him not to tip us off about his hacks! The position control is a really nice addition. Potentiometers added to each of the joints … [Read more...]
[Eric Gregori] had an OWI535 toy robotic arm. Although cheap (coming it at around $30) the arm is only set up to be used via a wired control box. [Eric] knew he could do better by adding computer control via a TI Launchpad and motor driver peripheral. The arm has shoulder, elbow, and wrist joints, a rotating base, and a gripper. All of these are actuated by 3V DC motors and have just two … [Read more...]
[Alejandro] and his friends recently finished a first prototype of scratch-built robotic arm. They've got some nice electronics bench equipment for use with a project like this, but for the actual fabrication work it's off to the kitchen. As you can see in the video after the break, they're using PVC as the stock material in this build. Flat sheets are produced by slitting a PVC pipe down the … [Read more...]
Bot gives head to passersby This free range robot was spotted at this year's Kinetica Art Fair. You can place your hand above it and it will stop and pour you a beer. That's if you consider 7/8 of a glass of head 'a beer'. Photo booth adds fun - consumes floor space Face it, photo booths are fun, and if they're free a lot of people will use them. This particular booth was built in … [Read more...]
[ross], a reader is working on a CD changing and ripping robot. The arm picks up a CD and the platform then rotates, stopping in front of the tray to drop the CD. A JB welded tire pump provides the vacuum pick up, while a brake light acts as a resistor to trick a PC power supply into operation. A Motor Shield beefs up an Arduino in order to drive the servos. … [Read more...]
