Mechanical Power Restrictions

**Q: Rule <R5> states that “The only allowable source of power for a VEX Robotics Competition Robot is a single (1) VEX 7.2V Robot Battery Pack.” How does this apply to VEX Pneumatics & Elastic Bands? Are we not allowed to store energy in these?

**A: This rule is referring to electrical power. Mechanical power derived from a change in potential energy, from an elastic band, or from stored compressed air in a VEX Robotics Pneumatic Tank is legal.

**Q: Are we allowed to store energy in the form of compressed air at the start of a VRC match in a VEX Pneumatic Tank (part of a VEX Robotics Pneumatic Tank)?

**A: Yes, this is legal. There are no restrictions against mechanical power from pneumatic compressed air. Note the robot must fulfill ALL other regulations specifically <S1> and <R5>. Exceeding the pressure restrictions would be a clear violation of <S1>.

**Q: ****Are we allowed to store energy in VEX Latex Tubing at the start of a VRC match by having the band pre-tensioned?

**A: Yes, this is legal. There are no restrictions against mechanical power from elastic potential energy at the start of the match. Note the robot must fulfill ALL other regulations specifically <S1> and <R5>.

**Q: ****Are we allowed to store mechanical potential energy at the start of a VRC match by placing a heavy weight high on our robot? This weight would then swing down and provide energy to unfold part of our robot.

**A: A: Yes, this is legal. There are no restrictions against mechanical power from mechanical potential energy at the start of the match. Note the robot must fulfill ALL other regulations specifically <S1> and <R5>.
