The WidowX Robot Arm Can Draw Better Than We Can!

Thursday, August 21st, 2014

TRC Member userasp9185 showed off some great examples of what you can do with the InterbotiX WidowX Robotic Arm. First asp9185 created a custom IK engine and control software in Visual Studio/C#. The ArbotiX robocontroller running the ROS sketch acts a pass-through, allowing the computer direct control over the servos. The software axxepts XYZ Cartesian coordinates and moves the arm to that position. A forward kinematics solver than confirms the position based on positional feedback values from the servos

The software can now preprocess an image to detect adges and contrast, and then randomly select pixels. The IK algorithm determines the best path to draw the pixel on the paper, allowing the robot arm to draw a version of the photo that was input into the software.

Introduction Video for the RobotGeek Snapper Arm

Wednesday, December 11th, 2013

If you haven’t heard yet, the RobotGeek Snapper Arm is out. The Snapper is a great hobby/educational arm which merges the worlds of Arduino and robotics. The Snapper has 29cm of reach, a sturdy slewing bearing base, Geekduino controller, and a manual control panel. Did we mention the Snapper has an all black sexy design too? He does!

Here is Kyle giving a quick overview of the Snapper Robot Arm.

pyPincher, an IKGUI tool for the PhantomX Pincher

Thursday, July 18th, 2013


Phil Williammee has created an application that can communicate with the the PhantomX Pincher through PyPose. pyPincher will allow you to control the Pincher via rotation, extension, and height, along with gripper angle and the gripper itself. The program will then also give you a 3D representation of the arm’s current position. You can even load different coordinates and toggle between them! This is just another great example of how users can leverage the open software and firmware of the InterbotiX robots to create custom setups.

RX-64s are crazy strong…

Monday, February 23rd, 2009

Our good friend Jon Hylands (who is an amazing Roboticist, definitely check out his work on the Bioloid system) is working on a few new projects and shot a quick video which is pretty impressive to anyone who has ever built a robotics arm. What you see in the video below is an RX-64 Robotis servo lifting a full coke can at a 30 cm arm length. While that seems trivial to we humans, packing that much torque into such a tiny servo is a great demonstration of how much servo technology has advanced in the last few years. The servo isn’t even being strained during these tests. You might note a bit of jerky movement, that is because the servo is being manually fed positional instructions via a slider bar. Most advanced robots use some form of interpolation which smooths movements considerably.

We’ll also be revealing our big internal project which uses 14 of the RX-64 servos in the near future… =)
