Tetrix Max Worm Gear 20:1 is perfect if you need more torque or slower output speed. It can be used to replace the 4:1 worm gear that comes with the TETRIX Worm Gear Box. Also, this set reduces the chance of back driving to almost zero.

The worm is steel and the worm gear is bronze.

• Material: SAE 841 Bronze Worm Gear; 303/304 Stainless Steel Worm

This mounting kit enables easy alignment of standard-size servo motor shafts to the TETRIX hole pattern. The flexible attachment options allow for a multitude of design possibilities. Includes mounting plate, bearings, stand-offs, and aluminum servo shaft to 4.7 mm steel D-shaft axle adapte

These 4 mm long bronze bushings are handy for tighter space requirements.

These plastic spacer/bushings are used in conjunction with 6 mm axles to keep your mechanisms and wheels running smoothly. Can also be used as a 2 mm spacer between metal surfaces.

This starter set includes what you need for students to get to building robots, including any of the three hero models, with step-by-step instructions in the builder’s guide.

This pack contains a noncontact distance measurement module that works at 42 kHz to transmit a digital signal to the TETRIX PRIZM Robotics Controller. The module detects the range of an object within 3 to 400 cm, enabling your robot to sense its surroundings. Comes with a mount, connecting sensor cable, and the hardware for attaching the sensor to the TETRIX hole pattern

This pack contains a line-tracker module that transmits a digital signal to the TETRIX PRIZM Robotics Controller, enabling a robot to follow a black line on a white background or vice versa. The sensor consists of two parts: an IR-emitting LED and an IR-sensitive phototransistor. Comes with a mount, connecting sensor cable, and the hardware needed for attaching the sensor to the TETRIX hole pattern.

Take your TETRIX robots to the next level with a stronger 12-volt DC motor with 100 rpm and 700 oz-in. of torque. The motor features a built-in, high-resolution Hall effect encoder for precise motor control. Based on user feedback and created specifically to withstand the stress of intense robotics competitions, this is our strongest TETRIX motor yet. TorqueNADO is compatible with allTetrix Max; DC Motor Mounts.

Specs:

• Weight: 324 grams
• Operating Voltage: 12 volts
• Length: 134.1 mm/5.29 inches
• Gear Ratios: 60:1
• Diameter: 37 mm

Designed to use with TETRIX PRIZM Robotics Controller, this motor controller connects to the PRIZM expansion port, enabling users to control up to six additional servo motors and two additional continuous rotation servo motors. Up to four motor controllers can be connected to the PRIZM expansion port. Additional power and expansion ports support daisy-chain configurations.

Supported programming languages include Arduino and EV3. The motor controller can be connected to the LEGO EV3 Brick. Software blocks can be downloaded from the Resources tab below.
