You will need to buy a few things: Spectrum DX-7 $300, CD-Rom Drive $30, super glue $5, duct tape $2, Solder $5, Wireless camera set from Geeks.com $30, Amphibian from propelrctoys.net $50, Sabertooth 12 RC Dual Motor Speed Controller $70, 2 CDs, and 3 Futaba S3305 High-Torque Servo Motors about $40 each but you can pick any kind of servo motor. This design will improve the orginal amphibian and you will have a camera so you can see on your tv screen what the robot is doing. Tools needed soldering iron, pliers, wire strippers
First Remove all of the electronics from that back of the CD-ROM Drive except the motor that controlls the motion for going in and out
now unscrew the water squirter and strip the wires so that you can see the copper
Now tape the water squirter onto the disk. Make sure to take it out of the slot because this one got messed up.
Now, super glue a servo to the bottom of the disk that you taped the squirter on. Use tape to support it while drying. After it is dry, super glue and tape the bottom of the servo to the other disk so that it can support the disk with the squirter ontop
Now I will tell you how to make the electronics.
First unscrew the servo motor's screws on the the bottom
then dismantle it after that then open it and pull the electronics out of the case
do this twice so you can use it for the squirter and the disk tray.
Now first desolder the motor there currently and solder in its place the wires of the water squirter in the first and the disk tray in the second
Part 3 --test
Plug the disk tray controller into gear, the water squirter into thro, the servo turning the water gun in AUX1 and test it out!
unscrew all of the screws on the base and take all the wires out except the two motor wires and the battery wires and for future use leave the wheel lifter wires there it will also give support
tape sabertooth controller inside the base and get the motor wires and plug them in. Also plug the battery wires in and put a switch in. Get the RC cables on the side of the wheel chassis up to the top and tape it on the side of the chassis. After you do that don't seal the inside shut.
Part 5 --test
Now the base should be controllable with the speed controller you will need to keep the battery that came with the robot so that you can power the speed controller. Unplug all of the current RC wires you have on the reciver except the battery for it. Plug the forward into ELE and Turn into Aile and put the reciver on the colsest circle and the battery in the dip next to the supports for the wheels. Now test it out, if it works go to the next steps otherwise try to see what is wrong. Also make sure that when you are supposed to turn you turn and when you need to go forward you go forward. If you go to the Reversing SW option on your controller you can try to fix it by reversing channals; like if you want to turn right but it turns left.
Part 6 --putting it together and testing it
Now duct tape the disk drive to the base's center so that it is secure. Next duct tape the reciver and battery down so the dont fall off when you are driving. Now tape on the camera to the front top center of the water squirter and tape the battery to the back rectangular part.
Now make sure you have all of your wires are plugged into these ports: Forward into ELE, Turn into Aile, disk tray controller into GEAR, water squirter into THRO, and the servo turning the water gun in AUX1
NOW YOU ARE DONE!
Just plug in the camera into the TV, turn on the controller, and try it out!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
