Tech Thursday #032: Soldering

Soldering is one of the most useful and necessary skills to have when working with any form of electronics. It can be as simple as soldering a joint on certain materials, or as complex as assembling PCB’s.

Tech Thursday #028: Available Track and Wheel Options

If there is one thing we have learned, it’s that track design is not trivial. We have been building treaded robots for over 10 years, and, at generation 4, they’ve been through many stages of evolution. It takes a lot of research and development in order to produce treads that stay on under tough circumstances. We’ve done it, performing NIST qualification tests using our LT2 robot and generatio...

Charging Time: Considering the Smart Charger for 12V SLA Batteries

Charging Time: Considering the Smart Charger for 12V SLA Batteries

Our smart charger is fast – but how fast, exactly? How long would it be for our 12V Lead Acid Battery Charger to take a 12v 20Ah from zero to 100%? In theory, a 20 Amp Hour battery will take 2 hours to charge. There are a couple things that come into play. First, the battery has to be rated for that fast of a charge. Some SLA batteries are only rated for 1/3C for charging (basically 1/3 of 2...

Tech Thursday #027: MLT-JR Platform and Program Examples

The MLT-JR is our lowest cost tracked platform and it’s powered with an Arduino! Equipped with spliceless molded tracks, 32mm motors, and a 11.1V 2200mAHr battery this isn’t your garden variety desktop robot. To make getting started easier, we’ve assembled some example Arduino sketches to act as a base to begin your own robotics development. Motor Demo This example serves as a mo...

Tech Thursday #026: Vectoring Robots

Vectoring movement is achieved through a sum of forces generated by each wheel. SuperDroid Robots offers many vectoring robots on its online store. We also have a support page for vectoring robots which details the theory of operation. Two main types of wheels are used. Figure 1: Omni wheels have smaller rollers on the edges that move completely perpendicular to the wheel itself. With this type of...

Tech Thursday #025: Power Drivers and Distribution

One of the first electrical decisions that must be made when building a robot is how you are going to power it and how you are going to get that power to where it needs to be. Here at SuperDroid Robots we strive to make this as simple as possible with a wide range of power distribution, drivers, and wiring kits. Power Drivers Power drivers are crucial in any robotic system even when you are only u...

Tech Thursday #024: Basic Drilling Procedures for All Robot Builders

Today’s Tech Thursday will cover some basic drilling and countersinking procedures.  We have added a few new parts to our store to aid in building robots. We have 3/32 inch drill bits (T-023-032) that are used to drill a hole for a #2 machine screw. It is also the right size to tap a 4-40 thread.  Our ATR hardware package (TD-021-000) contains #2 and #4 screws which makes a 3/32″ drill bit a...

Tech Thursday #023: Wireless Robot Control with an xBee

When you want to take your robot wireless but want to take it a step past R/C, an xBee is a prime candidate. The system works over 2.4GHz, similar to WiFi but what it provides is a simple wireless serial bridge. Meaning you can send a packet to the module and it’ll appear at the outputs of all xBees on that network. You don’t have to worry about subnets and IP addresses or any other ne...
