This notebook helps students record all their design work in one place. By using this notebook, students learn about the design process and complete tasks that lead them closer to the final design of a competition-ready, battery-operated car. The Engineering Notebook is used with the 3-D Printing: Vehicle Engineering Curriculum.

This kit is designed for the teacher to experiment with different variables after making a basic mousetrap vehicle. The kit includes the same types of basic materials as found in the introductory kit, plus other materials to allow you to explore different options for developing mechanical advantage. The demo kit includes CD-ROMs, plastic wheels (two sizes), mousetraps, different-length lever arms, string, brass tubing, washers, steel axles, acetal axles, glue, balsa wood, rubber bands, and a copy of Doc Fizzix’s Mousetrap Powered Cars & Boats.
No playmate needed for this seesaw!
Featuring just one axle and two wheels, The Seesaw has half the friction and rotational inertia acting against it as compared to other mousetrap vehicles. After the mousetrap releases, the racer’s chassis seesaws briefly before balancing out for a clean run.
All parts come precut and predrilled for quick and easy assembly. The Seesaw travels 15-20 meters on average. Requires white glue and needle-nose pliers, sold separately.
Designed for all speed contests and “king of the hill” climbing challenges, The TorqueMaster is engineered to provide as much as 100 percent more torque and extend the pulling force up to 50 percent longer than conventional systems! The TorqueMaster’s pulley system maximizes the winding of the mousetrap’s spring to 360 degrees, causing it to explode off the starting line. Requires a drill, scroll or hand saw, glue, and needle-nose pliers, sold separately.
Kids invest a lot of time, heart, and hope in the construction of competitive CO2 dragsters. Protect that investment with our Competition Carrier, a hard-on-the-outside, cushiony-on-the-inside carrying case for one dragster. Constructed from durable ABS plastic, it features securely fastening snap closures and molded handles for convenient carrying.
Inside the case rests a thick foam cushion scored into multiple 1/4" x 1/4" x 1-1/2" sections. Each section can be removed to hollow out a space that fits the contours of almost any vehicle design. When safely nestled in its foam cushion, the dragster is covered with a foam pad, adding another layer of protection for a vehicle on its way to a competitive event.
Outside dimensions: 12" H (at the handle) x 14" L x 3-1/3" W. Inside dimensions: 8-1/2" H x 12-3/4" L x 2-3/4" W.
When your class is building more robots than you have remote controls for, it’s handy to have extra receivers so students can attach them while constructing their robots and not have to remove them right after running the robots. This option is a serious savings compared to buying more remote controls. Six-channel, 2.4 GHz receiver.
With Servo Commander, any animatronic device built with standard hobby servos can be programmed to move without a computer!
Simply connect batteries and up to five servos to the circuit board, rotate the controls in the direction you wish the servos to move, and press a button to save the sequence of movements. More sequences that involve all or some of the servos, up to a total of 51, can be saved. After programming is finished, switch on the circuit board and watch the animatron execute its moves!
Servo Commander is fully assembled and includes a servo motor, 9 V battery, rechargeable four-cell battery pack, circuit board, and instructions. Additional servos sold separately.
Get programmable control while keeping your robot looking clean and tidy.
The TETRIX® Autonomous Mounting Deck features precut holes to make it easy to mount an Arduino or Parallax Basic Stamp programmable controller to a TETRIX robot, as well as the TETRIX DC Motor Speed Controller.
The deck is sized to fit the TETRIX hole pattern spacing so it can be used on a variety of robot designs. Made from 1/8" black acrylic and measures 6.25" x 3.75". Includes screws, nuts, kep nuts, and acrylic spacers for mounting components.
Featuring fully proportional forward and reverse speed control, this servo enables precise movements of robot designs. Unlike other servos that have a limited range of motion, this servo rotates continuously in either direction – as needed for wheels. This high-quality servo is designed with a wide neutral dead band to eliminate the “creep” that occurs in many other continuous rotation servos. Dual ball bearings on the output shaft ensure long-lasting performance. Note: This servo does not have position feedback.
When you need double the power, this bracket does the trick. Use it to attach two motors side by side. Made of heavy-duty aluminum.
Used with the Frame Mounting Bracket, the Pivot Bracket creates strong, durable pivot joints while minimizing side load on the servo shaft. Compatible only with TETRIX® Quarter-Scale Servo Frame Mounting Bracket (39383); includes a 3 mm Bearing Pack.
