• Includes the chassis, hardware, and wiring kits.
• Gear Motors: Four (4) IG42 240 RPM Gear Motors (one per axle/wheel).
• Wheels: Two (2) sets of 6 inch pneumatic wheels.
• Battery System: Two (2) Interstate 12V 8 Ah Lead Acid Battery providing 1-4 hours of operation depending on use.
• Motor Controller(s): One (1) Sabertooth Dual 12A RC Motor Driver.
• Control System: One (1) FLYSKY FS-i6 2.4Ghz 6Ch transmitter and receiver.

Available Options

While we recommend the standard configuration, if you would like to customize your robot we offer many options you can choose from at the bottom of the page. The TP-132-042 kit allows for a wide range of customizations based on your needs. We offer a variety of motor controllers, batteries, RC controllers, and encoders so you can configure the robot to meet your requirements. The weight of the robot will vary depending on how the robot is configured (batteries are the main cause of this). You can find detailed specs such as weight and dimensions by clicking on the component and viewing its product page. For help selecting components, read the information below.

• Wheels: Choose from our selection of wheels. You can choose from our standard grip pneumatic tires or if more traction is required you can choose our rugged all terrain traction lug tires.
• Gear Motors: Choose from our selection of different RPM gear motors. As you go down in RPM, your payload capacity will go up but your speed will go down. As you go up in RPM, your payload capacity will go down but your speed will go up.
• Batteries: We offer a few different battery options but there are two types of batteries that we recommend using with this kit: Lead Acid and LiFePO₄. The lead acid batteries are much less expensive but are heavier, do not provide any internal circuit protection, and can survive anywhere from about 200-1000 charge cycles. The LiFePO₄ batteries are more expensive but are much lighter, have internal circuit breakers to prevent damaging themselves, and can survive about 1000-3000 charge cycles. The charge cycle estimates are based on the recommended depth of discharge for each battery cycle. A lead acid battery is only recommended to be discharged to about 50% of it's capacity while a LiFePO₄ battery can be discharged to 100% with no long term affects.
• Motor Controllers: Choose from our selection of RoboteQ, Sabertooth, and RoboClaw motor controllers. In most configurations, a single motor controller is all that is required. The left side motors share a channel while the right side motors share the other channel. We offer the option to double the quantity in case you require encoders on all four motors.
• Encoders: This robot can be configured with encoders used for odometry and/or speed control. They are very useful if you are planning on making your robot autonomous or semi-autonomous. For encoders, select motors with encoders and the appropriate motor controller and encoder hookup. Linked below in the documentation and support section are some resources that help in selecting encoder options.
• RC Controllers: We offer several options for controlling your platform. If you are planning on using this robot with a microcontroller, Wi-Fi control package, or similar device an RC controller is not necessary.
• WiFi Control Package: We offer an option to control your robot with a WiFi package. If you wish to have encoder feedback, there is an option for WiFi Package with encoder input.
• Optional Accessories: You can customize your robot to have an upper deck, skid guard, bumpers and a roll cage. If you would like both front and back bumpers please select both.
• Assembly: You can choose if you'd like our team to assemble the kit prior to delivery. If you have selected encoders and want assembly you must select the assembly with encoders. The in-house assembly will typically add a week to the delivery time.
