Since we don't know the material or design students will choose for their robotic arm, we've put together this kit with the parts they must use, such as:  Syringe,  syringe holders, magnet wire, bolt and washers for magnet head, and wire. In addition, we have added  1x2x12 pieces of pine and  small aluminum plates. This is an open-ended design competition so we do not provide plans; we recommend purchasing the Hydraulic Robotic Arm Demo Unit (841329) in order to get ideas. Requires Competition Arena Controllers (841336) or the Electronic Power Pack Controllers (841330). This kit requires design, manufacture and assembly.
