2
Chassis Material

• HDPE (High Density Polyethylene) Low cost, low
  weight, easily to work with
• Often used as 3D printer filament
• Sheet Metal, Aluminum Low cost, low weight

Wheels

• Mecanum wheels allow for multidirectional
  movement without turning
• No reputable sources on difference in power
  consumption
• Same force and velocity as standard wheel
• Traction may be an issue in either case
• Mecanum wheels remove issue of reorienting
  targeting system during line following

5
Microcontroller

• We recommend the Arduino Mega or Due
• Both more robust than Uno
• Mega has higher operating voltage (5v) compared
  to Due (3.3v)
• Due has more on board memory (512 Kb) as opposed
  to Mega (128 Kb)
• Plenty of I0 Pins (12 PWM for Due and 15 PWM for
  Mega)

6
Batteries

• High quality rechargeable batteries are preferred
  for high drain devices
• More likely to provide advertised output
• We recommend 7.4 Volt, 2100 mAh RC batteries
• More than enough voltage and current for the
  competition limits

7
Servos/Motors

• Good quality servos are a must
• Light, quick acceleration, smooth operation and
  faster response time
