Antweight Combat robot, Dynamo

thingiverse

This is my competition-ready battle bot, tipping the scales at a mere 150 grams. Dubbed DynamoWedge, it boasts an innovative design featuring tracks that allow it to flip itself back over by moving forward and then rapidly decelerating. The compact size and weight of this robot fit neatly within the competition guidelines. As version 9 has now arrived, some significant enhancements have been made to its build: - Metal screws were added at the front for reinforcing structural components - Spacing blocks are integrated between the motors to prevent accidental insertion Additionally, several improvements in terms of size and weight reduction have been incorporated around the framework. Below is the detailed list of components needed to bring this formidable robot into being: - Micro Metal Gearmotors with either a 30:1 or 50:1 ratio work flawlessly (find them at RobotGear.com.au/Product.aspx/Details/313-30-1-Micro-Metal-Gearmotor-High-Power) - The 22T Track Set can be purchased at RobotGear.com.au/Product.aspx/Details/566 - A pair of escs off eBay, each boasting 10A brushed capability - V Tail Mixer from Hobby King serves as a controller for the motors As for powering this dynamic robot, the battery has been handpicked to perfectly match the remaining weight left after construction. The preferred choice was a compact yet potent 2S option sourced from HobbyKing. More recent revisions have seen an overhaul in electronics: - A change of esc now utilises one from BotBitz.com.au/product/product?product_id=50 - Despite this change, HV micro motor with its 30:1 ratio remains part of the design - With the revised setup, there's ample room for installing a layer of metal on the front to provide protection against opponents' spinning attacks Catch the robot in action with this link to an entertaining video: https://www.youtube.com/watch?v=7KuWHFXtmvc In addition, a bespoke stand was crafted to securely support the robot. Now, regarding print settings used: - The print environment employed an XYZ printer - It printed flat base with 30% infill strength; printing on its side proved the strongest in tests conducted by me - However, with tabs integrated into design after reevaluating, results have shifted toward flat print becoming stronger Lastly, any adjustments made post-printing would include: - Drilling out idle wheel holes using a 2.5mm drill bit - Installing balance leads for convenient charging from the side - (Optionally, you can position the charge lead at the rear above the motor)
