This is my first attempt at a walking robot...thoroughly inspired by Penny and Stomper. :)
Chassis : I had loads of pen refill tubes lying around on my table (by-product of a month of exams) so I used those to build the legs.They're connected to old mechano pieces using hot glue,this is then connected to the servos.For the main body I used an old plastic case I had lying around.The dimensions are 16cm X 13cm X 9cm (L x B x H).
MCU : Used a pro mini clone for the mcu.It's soldered on to the pcb along with the header pins for the servos.
Sensors : I've used an HCSR04 ultrasonic sensor for obstacle avoidance and also an LDR so that it wobbles happily when someone touches it on the head (see video).There is also a voltage divider circuit used to measure the battery voltage so that the robot stops moving when the voltage drops below a specified value.
Head : The cover for the head I got from a broken torch and the ultrasonic sensor fit perfectly in there...plus it looked a bit like Wall-E's head.There's a blue LED mounted inside the cover which acts as a backlight.
Battery : I've used two mobile phone Lipo batteries(7.4v) which go to a 5v regulator which supplies power to the servos.
Here's some more pictures :
Right now the walking is still a bit weird since the screws keep becoming loose but a bit of super glue should fix that.
I've also made an instructable for the hexapod.
Cheers :)
