PicoRoach is a six legged walking robot kit suitable for intermediate solderers. You'll also need to have access to some tools (eg. pop-rivet gun & pliers).
Resistors are the smallest component. They are non-polarised. Components should be positioned as close to the PCB as possible to avoid bending and braking of the leads.
Align the IC socket. Shorten to 3cm, strip, and route the 9V Battery Snap wires. The 5V regulator does not require a rivet. The monolithic capacitors are non-polarised. Plug the programming cable into the programming socket before soldering, to ensure the pins stay in place.
Peel off Plastic cover. De-burr the Middle-Leg on the inside curves so it moves freely on the PCB. Keep the PCB face up and place the middle leg in position. Then solder the Pin-Headers in place.
Cut the wires to length and bend ends at 90 degrees, 7mm from the ends, then again at 3mm. De-burr plastic legs and pivots that rub on other plastic or PCB parts. Place two legs on each lower pivot, then place the upper pivots, slide onto PCB ends. Test movement is free. Secure with one rivet. Retest for movement. Secure with other rivets.
Make antennae: bend wire tightly and slide onto micro-switches.
Be careful: wire is tensile and will snap easily.
Solder will not stick to switch metal.
Pop the rivets downwards: (switch may crack but will still work). Use a multimeter to test if needed.
Use resistor lead offcuts to solder PCB to switches.
Assemble motors and screw together with plastic mounts.
Screw to the PCB.
Test-fit the middle leg and check movement. Note: Servos are quite fragile.
Adjust plastic mounts if needed.
Carefully wiggle the middle leg back off the servo.
Plug servo wires to pin-headers: Yellow wire aligns with white dot.
Hook wire onto levers and leave hanging (not to servos).
Plug on battery.
Mount with Blu-Tack®.
Put PIC® in IC socket with notch oriented.
Instant Program (if required).
Turn on and off quickly to center the servos. Put horns in place.
