TicTacToe Robot Arm (2010) TicTacToe game Robot Arm application. Robot Arm with 5 degrees of freedom plus gripper, made with Lego Technic, LynxMotion and custom made parts controlled with a Parallax Propeller Microprocessor. Game board made with an array of 9 CNY70 infrared light emitters and detectors. User interface with 2 line LCD display and… Read More TicTacToe Robot Arm (2010)
Robomagellan, RC Truck Hacked version (2010) This version of my 2010 Robomagellan robot was based on a RC Toy Truck base where the original truck electronics board was replaced with a DFRobot Motor Controller (L298N H-Bridge) and the original electromagent used for steering was replaced with a Hitec HS-322HD servo. Additional sensors (sensor overkill perhaps)… Read More Robomagellan, RC Truck Hacked version (2010)
Experimental robot arm with 5 DOF (Degrees of Freedom) plus actuator (gripper). The Lego version was to shaky and weak so replaced from the elbow down with Aluminum Servo Erector brackets from Lynxmotion. Gripper, wrist and wrist rotate made with Lego Technic and aluminum parts, elbow, shoulder and base made with Lynxmotion parts. Parallax Propeller Proto… Read More Robotic Arm, Lego gripper + Lynxmotion Servo Erector elbow, shoulder and base version (2010)
My first Robomagellan robot for the Ottawa Robotic Enthusiasts (ORE) Robomagellan competition was based on a RC Truck with minimal hacking. In order to preserve the RC Truck only the body was removed and all the robot components were mounted in an acrylic base which could easily be removed. The Radio Control was mounted in the acrylic… Read More Robomagellan, RC Truck Minimum hacking version (2010)
This object (http://obex.parallax.com/object/224) allows the control of up to 14 standard servos. I wrote it for my 2010 Robotic Arm. It requires 1 cog. 2 cogs required for Accelerated/Decelerated Moves. This object is based on the Servos for PE Kit.spin but incorporates many new features like: a) Three different type of movements: Immediate, Gradual and Accelerated/Decelerated… Read More Propeller Object: Enhanced Servo Controller with Acceleration (2010)
Method and material I used to easily connect servos to Lego Technic projects. Used for my 2010 Robotic Arm. This tip was based on this source: Tutorial: Connect LEGO wheels an gears to a RoboBuilder servo.
Experimental robot arm with 4 DOF (Degrees of Freedom) plus actuator (gripper). Frame made of Lego Technic parts and aluminum sheet. Robot Gripper made of cheap Turnigy TG9e (3) servos ($1.99 each at hobbyking.com), elbow and shoulder use HiTec Servos. Parallax Propeller Proto Board used to generate the PWM signals for the Servos. A custom spin… Read More Robotic Arm, Lego Technic version (2010)
A maze solver robot. Circular base with IR sensors for line following and IR sensors for wall detection. Stepper motors with rudimentary wood wheels used for locomotion. Tethered to an Apple IIe. Recursive maze solver program written in Pascal. This was my first Robotic project which my friend Hector and I did in our last… Read More My first Robot, a Maze Solver Mouse (Ratón Inteligente) (1988)
