DEWBOT XVIII Arm

Due to the long reach required to score (especially CONEs) on the Top ROW, CHARGED UP seems to be a classic Arm Game. Nice change, but Sab-BOT-age has built only four Arm Robots to-date. These were:

• 

  DEWBOT I - Triple Play - 2005

• 

  DEWBOT III - Rack 'n Roll - 2007

• 

  DEWBOT VII - Logomotion - 2011

• 

  DEWBOT XIV - Power Up - 2018

The centerline of the Top ROW CONE NODEs are 3' 3-3/4" from the GRID front. Add 3-1/2" for bumpers and 2'1/2" for the radius of our rotating paddles and you are just shy of 3' 10". Maximum extension is 4' beyond the frame perimeter. This requires either a 2-axis Arm or a 1-axis Arm combined with a directionally extending lift. Sab-BOT-age picked the 2-axis Arm without extension.

We defined the following terms in talking about the Arm:

• Shoulder - The rotational axis on the Chassis. The Shoulder is driven by the Shoulder Gearbox
• Humerus - The Arm section extending from the Shoulder, terminating at the:
• Elbow - The 2^nd rotational axis, used to articulate the:
• Radius & Ulna - A pair of structural elements terminating with the Monkey Claw

The Elbow is driven by the Elbow Gearbox.
