Hexy Assembly Instructions
Carefully follow the step-by-step instructions found here
-
Be careful about power: The servos can be damaged if they are supplied too much voltage. The servo power on the board is NOT regulated and the servos are rated at 4.8v. Overvoltage will shorten the servo life, may cause spasming or jittery servo behaviour. 5xAAA PowerEx batteries have been measured at 6.4V, which is probably too much.
-
Test the Servos: Be sure to test the servos before attaching them to the legs. A good way to do so is by running PoMoCo (see below), plugging the servos into pin 4 and using the sliders in the PoMoCo GUI to verify full range of motion.
-
Center the Servos: Centering the servos while attaching them to the legs is very important but sometimes will not look 100% perfect. Fortunately, PoMoCo allows for additional calibrate your servos and save the offsets into a config file that can be re-used later.
-
Attaching the Servo Horns: Due to the manufacturing method, the screw holes that you attach the servo horns to have a smaller diameter on one side of the acrylic parts than on the other. This prevents the short screws from "biting" into the plastic when you attach them on the side with the wider diameter. This easily solved by flipping the part over so that the smaller-diameter hole faces the horn.
-
Reliable Bluetooth: Detached/wireless operation of the bluetooth module requires both servo and logic power supplies. When operating off servo power only the bluetooth module may not initialize or may drop link during operation.
Set up the ultrasonic distance module
Note: The bluetooth module will either not power up (flashing red) and/or it can lose link (solid red) if the available power is too low. Provide logic power (e.g. a 9v) as well as servo power to mitigate the problem.
