|TecArm6v2 by David Buckley||2012|
I siffened the limbs and added sliding feet for the waist movement to ease the strain on the servo-horn a made the gripper gear driven to balance the finger movement. The shop never materialised so the TecArm6v2 was put back on the shelf.
In 2020 during Covid lock-down I was talking to a friend who had purchased a hobby robot-arm from China and decided to look at my TecArm6v2 again. The original GUI written by Milford no longer worked in Windows-10 so I added an Aduino nano to accept high level commands from a serial-terminal and send the necessary codes to the existing servo controller on the arm. (I did the same for the TecArm5 prototype.)
