The chassis is constructed from 1/16 inch thick (1.58 mm) 5052 aluminum sheet metal with a lightly grained black anodized finish for increased durability and scratch resistance. Robust 7.2 VDC motors with all-metal-gear construction use machined aluminum hubs to positively engage the 4 7/8 inch (12.4 cm) diameter wheels. The result is a solid and reliable robot chassis that moves with smoothness and quick agility. The motors speed is 310 RPM at 7.2 V which equates to approximately 6.6 feet/sec (2.0 m/s). Each chassis panel comes furnished with a variety of mounting holes and slots to accommodate a wide range of control boards and accessories. With almost limitless possibilities you can have an autonomous mobile robot up and running in no-time.

Each step will describe the parts and tools required and then the procedure to assemble them. Each step contains a CAD drawing as a visual aid to the instructions. Be sure to follow each step carefully. Preparation Match the Bill of Materials against the parts in your kit to make sure all parts are present. Find a clean workspace on which to assemble your chassis. You might want to put down some newspaper or cardboard so that the edges of the metal parts do not scratch the work surface. Organize tools and parts prior to starting the assembly and separate parts by type to make it easier to gather them during the assembly process. Throughout the assembly process, when tightening screws be sure to get them nice and snug but do not over-tighten them or you may strip the threads or heads of screws. Additional Tools Required Two hex keys and one Phillips/flathead screwdriver are provided. The following additional tools are required: Safety glasses O-ring pliers if you have them (these are Small pair of needle-nosed pliers optional, but make things easier) Copyright Parallax Inc.
