Update: The contest is now closed. I’ll be gathering the entires and sending them to our judges over the next week or two. Stay tuned for a post announcing the winners. If you won I will also contact you via email. Thanks and good luck!
The past few months have been a lot of fun, with us giving awa
how do I know the contest is over, and the winners are selected, when I’m not one of the winners? How can I be shure I didn’t win? do we get emailed for that?
thank you
I haven’t actually done anything in robotics to date. However, I would use parts won to start a project to introduce my children & myself to the marvels & possibilities of robotics and machine vision.
I plain to start simple and eventually incorporate CMOS imaging devices from my employer & utilize & expand my image processing skills.
I’m so late because i am working on another project and i hoped to completed before the deadline of this contest…but I’m still far away from finishing it.
So i will present in this contest my first robot: it’s an easy robot, but i still have fun with it! I didn’t get lucky in the past months in the GoRobotics contest, so I hope to get it this time!
The post on Robotbox tells everything, so i don’t want to bother you here with the details.
25 DoF humanoid robot, wears clothes, can participate in soccer and kung-fu. Has the ability to get up from prone position, walk, kick a ball, bat (as in baseball) as well as a large variety of other things.
Controller is Gumstix Verdex, running and Arm processor, software is custom written to run the 25 Robotis Dynamixels. Trajectory generation is done through both S-curve point-to-point, Bezier PTP and inverse kinematics patterned gaits. Full interrupt control driven over bluetooth on a PS3 controller for semi-autonomous control of the robot.
All mechanical work is custom, made from mostly aircraft grade aluminum (5052), designed on Autodesk inventor, created using a Sherline CNC mill. Other components are made from 3D blocks of reinforced nylon, cut from the same mill.
Runs off two hotswappable LiPo batteries, placed in the legs to balance the CoM near the pelvic region of the robot - extremely close to that of a scaled human. Arm to Leg is proportioned to avg. human. Has full hand with flexible fingers for gripping a variety of objects (anything from a small ball, a baseball bat or a pen/marker).
This is a very simple crawler robot using three servos and a Basic Stamp 2. It can do most of the moves of the 16 servo hexapods at one tenth the price. Next step is to add radio control and maybe a camera.
Blind Lemon handles basic navigation and is armed with a bass drumstick thumper at the rear and a high hat drumstick on his left side. His front bumper switch is used for collision detection. He currently has three drumbeats he alternates between. I am currently experimenting with adding dance moves and more beats.
My goal with Blind Lemon was to get as much out of the little Picaxe-08M processor as I could. I used my dual Y-Bridge motor control design so I could drive with only 3 processor outputs, rather than 4 outputs for a traditional dual H-Bridge. That left me one dedicated input and one input/output.
That wasn’t enough, so I added a DPDT relay. One Picaxe output controls the relay, and now I can get double duty from the other four pins.
Pin3 on the Picaxe-08M is a dedicated input and is being used for the bump switch. The other three switches allow motor control in one mode and drum and speaker outputs in the other.
An autonomous guided vehicle was built that could avoid particular objects on a course that involved line following, part detection, ultrasonic range finding etc.
