The Double Snakes FQJ-2 table tennis robot is an advanced 2 wheel Pre-Programmed robot.
The FQJ-2 robot is the advanced model compared to its little brother, the FQJ-1. The FQJ-1 model has a more basic control panel with fewer options. The FQJ-2 model comes as a “coach’s trainer” type of robot. It has a separate IR remote that can be used by a trainer/coach/friend, to use while you’re hitting balls. Not that everyone will have a coach with them while using the robot, but you can also put the small remote in your pocket while playing to start and stop the robot or change head positions if needed.
The Control Pad for this Double Snakes robot is set up with “pre-programmed” single serve and shot buttons. Basically, you just hit a single button on the control pad and it will perform a shot with pre set head angle and motor settings. The yellow buttons on the pad are for pre set ‘shots”. The pink pre set buttons are for a few various serves. This actually is a nice setup to quick practice a certain shot while being able to then change a few motor or head movement settings to get it set to throw a certain angle shot at you. You can then always return to that specific button’s pre programmed setting at any time. While having those particular “pre programmed” settings, the control pad allows you change all head movement from separate keys on the pad. This is a very nice feature to quickly change the head position without walking back and forth to the robot end.
You can quickly move the head in several different ways with the control pad. One set of up and down buttons moves the head vertically from high angle down to a low service angle position. Another set of up and down buttons will move the spin rotation angle of the head, from straight up and down to full 90 degree for true side spin balls.
