BattleBot description BattleBots is the sport of
remote-controlled robotic combat. Contestants all
over the world design robot warriors to compete
in a fast-paced, ruthless competition to see who
can destroy their opponents robot first. Project
purpose -Assist IUPUI Robotics team. -Gain
experience dealing with design criteria. -Learn
integration of technologies and principles of
systems design. Project expectations -Complete
design of a BattleBot structure, armor, drive
system and weapon. -Design within competition
parameters - Must perform competitively -
Opponents of the IUPUI BattleBot must be pounded
into Oblivion!! Final Battlebot Design -
Battlebot weight 118 lbs - Battlebot cost
2300 - Ram Attack 4800 lb force. Punch
Attack 3000 lb force - Adequate Ram Attacks per
match, 35 Pneumatic Punch Attacks/Match -
Battlebot Run Time 20 minutes

Weight The weight limits are 40 to 120 lbs.
Final weight was 118lbs Challenge The plating
on the chassis for armor was the heaviest part of
the robot and the chassis was continuously
modified to minimize plating. Cost Budget was
set by IUPUI BattleBot team at 2500. The actual
cost from BOM is close to 2300. Challenge
Throughout the process the cost gradually climbed
due to the need to chose lighter weight
components without compromising quality. Force
of Attack The ability to inflict damage is a
BattleBots main function. Ram force attack
delivered by BattleBot ram provides approximately
5000 lb-force. Pneumatic Punch - delivers a force
of 3000 lb behind a tool grade steel punch.
Challenge Designing a robot that could inflict
maximum damage without damaging itself.
Attacks Per Round BattleBot is built to run and
ram for the entire match. The pneumatic punch is
able to deliver 35 punches a match. Challenge
As the chosen cylinder got bigger the force
applied rose as well as weight. The larger the
cylinder, the fewer punches could be achieved a
match. Current Draw The BattleBot must run for
the entire 6 minutes of the match. Onboard
battery has 18amphour rating. Worst case - robot
will run at stall torque (pushing against a wall
the entire match) and pull 200 amps constant
current. At this rate the battery will die in
5.4 minutes. A realistic average of 40-75 amps
over the entire match shows battery will be more
than adequate for the 6 minute match.
Challenge Each battery weights 18 lbs and
therefore we must design the electrical system
so only one is needed.
