Robot Description

 Prakttismate robots consist of a recycle net, a remote control and the robot itself. Let me start by describing how the robot is set up for use.

Robot Setup

The recycle net has a clamp for the right side and one for the left side of the table. It is obvious from the drawings that are supplied in the manual, which is right and which is left. Attach one of the net clamps by placing it over the right or left side of the table. Turn the clamp screw to tighten the clamp to the table. Stretch the net to the other side of the table and attach the other clamp. Pull the vertical posts up and lock them in their upright position using the locking pin at the elbow.

Ensure that the robot clamp screw is unthreaded enough to allow it to fit onto the table. Bring the robot clamp to the table and attach it wherever you would like it to be on the table-end (anywhere along the table-end within the net enclosure). Bring the robot to the clamp and insert the clamp rod into the cylinder block on the robot. Check that the robot is standing at 90 degrees to the table top and turn the screw in the cylinder block to lock the robot in that position.

Pull one triangular side section of the net and use its hook to fasten its end to the game net frame as shown in the figure provided. Repeat this for the other side of the net. Pull the front edge of the bottom of the net upward in the vicinity of the robot and hitch an area on both sides of the robot feeder to the serrated hook provided on the robot clamp.

Clamp the remote control to the side of the table on the player's side. Run the remote cable under the table and bring its end through the loop in the bottom of the net at the serrated hook. Connect the cable to the robot receptacle. Make sure that the power switch on the remote control is in the off position and plug the power supply cable into a power outlet.

Now let's look at the remote control. The remote control has four control knobs and six switches. Of the six switches, four are assigned to controls to enable or disable the controls individually. The four controllable parameters are: Top-spin, back-spin (under-spin), oscillation (head sweep) rate and timer/feeder rate. The other two switches are for power and loop.

You can adjust the height of the robot head by loosening the height adjustment knob at the back of the robot then slide the robot head up or down to the desired height. You can tilt the head up or down by loosening the head tilt knob on the side of the head carriage, set the desired horizontal projection path of the balls then lock the head in that position with the knob. You can twist the head through 360 degrees to produce any spin you like. The twist friction is already set. All you need to do is twist the head.

The oscillation width is set by a single screw at the oscillator motor. You will need the correct size nut driver and wrench, or two wrenches to loosen and tighten the screw. The sweep can be set in infinitely small amounts so that it can, for example, be say 2 inches (5 CM) or it can be the entire width of the table.

YOU NEED TO PULL UP THE BACK OF THE NET RIGHT BEHIND THE ROBOT AND GIVE IT SOME TENSION. This allows the balls to transfer from one side of feeder to the other. Use the pin at the top of the tube to hitch the net after you have pulled it up for tension. If your robot is an earlier version and does not have a pin, you can add one.  Drill a small hole approximately 3/16", (4.77 mm) at 1.25", (31.75mm) from the top of the ball return tube. Drill the hole approximately half way around the tube at this position. Insert a flat head 6-32x 2.0"L or a 3mmx50mm screw into the hole from inside to out. Use an appropriate nut to fasten screw to the tube.
