Nuts and Volts - January 2018

the motor will not be stalled for long periods.

RedLine Motor with Pinion: This variation of the RedLine comes with a 12-tooth 32 DP pinion already pressed on. This reduces the risk of damaging the motor during pinion installation. Pinion gears are sold separately.

Vent Plate Spacer: This product is designed to be placed between a 775 motor or 550 motor and the mount plate of a gearbox. It allows air to enter from the side and pass through the motor via the vent holes in the face of the motor.

Allowing this airflow typically requires machine time and customization of gearboxes. This simple lightweight spacer is an ideal solution for motor preservation.

BaneBots Planetary Gearboxes: Lightweight, strong, and reliable, the 57 Sport and CIM Sport are the latest innovation in high performance planetary gearboxes from BaneBots and AndyMark.

The cold formed steel gears inside these gearboxes are a 0.7 module tooth profile which is 40% larger than the majority of planetary gearbox gears previously used on competition robots.

The gears are larger, but the housing's size has been optimized to not use any unnecessary material.

This means you get more reliability without sacrificing precious space.

This housing is also one solid piece of aluminum, ensuring that there is no possibility for misalignment of the stages during assembly or use.

DeCIMate: This gearbox comes with two AndyMark RedLine motors, providing an output geometry and weight similar to the popular CIM motor, but with almost twice the power.

Use this anywhere you would utilize a CIM with its identical output shaft and mounting geometry.

PG Gearmotors: This is the popular PG188 and PG71 series of gearmotors available now with 1/2” or 3/8” hex output shafts.

These planetary gearboxes are designed to attach directly to hex parts such as wheels, sprockets, and gears.

Wheels

4” Performance Wheels: These popular 4” wheels have gone through a design modification to be as solid as ever. Made from extrusions, the new 4” performance wheels are now available in 1/2” hex bore and 1.125 bearing bore versions.

6” SR Mecanum Wheels: AndyMark has offered Mecanum wheels for years, but with customer feedback and a desire to make the best Mecanum wheel offered, they have re-vamped the 6” Mecanum wheel product line.

The 6” SR Mecanum wheels provide a smooth ride for competitive and education robots.

Sprockets Single Roller Chain Sprockets, 3/8 and 1/2 Hex:

These are new 18 and 24 tooth sprocket options for use with motors and gearboxes.

AFFORDABLE TESTBED WITH

BLADE AND RASP PI

BitScope Designs — developer of BitScope Blade: an infrastructure platform for Raspberry Pi available globally via element14 — has built a large Raspberry Pi cluster for a pilot conceived at Los Alamos National Laboratory (LANL).

The 750 node cluster, comprising five rack-mount BitScope Cluster Modules — each with 150 x 64-bit quad-core RaspPi ARM boards and integrated network switches — is the first step in a program run by the New Mexico Consortium (NMC): an organization of three NM Universities that is led by LANL.

With up to 3,000 cores working together, the cluster gives developers and researchers exclusive time on an inexpensive but highly parallelized platform for test and validation of scalable system software technologies.

Gary Grider, leader of the High Performance Computing Division at Los Alamos National Laboratory and home of the Trinity supercomputer said: “It’s not like you can keep a petascale machine around for R&D work in scalable systems software. The Raspberry Pi modules let developers figure out how to write this software and get it to work reliably without having a dedicated testbed of the same size, which would cost a quarter billion dollars and Looking around for a solution to the challenges facing HPC Systems Software developers, Grider said, he “suddenly realized the Raspberry Pi was an inexpensive computer using two to three watts that you could use to build a several-thousand-node system large enough to provide a low-cost/low-power testbed to enable this R&D.”
