Building a robot army with the ATmega328 MCU



The Robot Army crew has debuted a DIY Delta Robot kit powered by Atmel’s versatile ATmega328 microcontroller (MCU) for the rapidly growing Maker community.

The kit includes all mechanical pieces in grey and neon yellow plastic (the yellow fluoresces under black light), spacers, brackets, ball bearings and hardware required for assembly. In addition, the kit is packed with electronic components, PCB and wire harnesses.

A more specific hardware breakdown is as follows:

  • 1 brain board PCB
  • 
6 arms
  • 3 servo paddles
  • 
3 servo brackets
  • 1 end effector
  • 
6 base spacers
  • 
4 PCB spacers
  • 
12 steel balls
  • 
3 Power HD servo motors
  • 2 acrylic mounting plates
  • 
1 RGB LED with wire harness
  • 
1 dome light defuser
  • Hardware required for assembly (M3 socket head cap screws)
  • 
1 AA battery holder with switch

The ‘Hex Brain’ PCB, which drives all the servo motors and the colored LED, is powered by Atmel’s ATmega328 MCU, with all pins accessible for use. The brain also includes programming headers so Makers can easily reflash the chip’s memory.

On the software side, the PCB is loaded with example code to implement the inverse kinematic math needed to drive a delta robot. Although there are several available routines, the basic skeleton code can be used as an outline for more advanced projects.
