Designed by David Buckley the TecArm series are simple robust robot arms powered by servos and controlled by serial commands from a host computer such as a desktop PC or a Basic Stamp. The arms are easily assembled using a small screwdriver, a pair of pliers and wood-glue.
The TecArm6 has six servos, a two-axis wrist and a 200 gram payload parallel-finger gripper that will open to 85 mm. It will easily pick up tennis balls or half empty drink-cans (a full can is just too heavy at full reach).
The TecArm5 has five servos, and a one-axis wrist. Otherwise they are the same.
The newly available GUI PC-software allows total control of the arm from both the mouse or movement-scripts.
The TecArm6 in the photo has been dyed with wood stain just to show what you can do.
The TecArms are available from Milford Instruments.
