ablation

Ablation is the second Repeat Robotics Beetleweight. It is a largely experimental design. It is the first of our robots to use our custom brushless drive, and it is the first robot designed to be made on a CNC router. It features 4 banebots wheels with drive motors located between the wheels. The hub is printed from Onyx on a markforged printer and uses 8-32 standoffs to transfer most of the torque between the two weapon disks. The asymmetric single tooth weapon disks are 3/8" AR500 and spin at around 250mph storing up to 1kJ of energy. It also features several front attachments.

Ablation competed in Spinner's spring but had problems with being inverted.
In our second competition, Ablation struggled with surviving massive hits against large horizontal spinners. It needs upgrades in both the weapon system and front armor in order to improve its reliability in matches with massive hits.

MEdium Rare

Medium Rare is the first Repeat Robotics Beetleweight. Its parts are designed to be manufactured by a waterjet and 2.5 axis CNC mill. Medium Rare currently uses two 22mm brushed gearmotors for drive, but we plan on upgrading to brushless drive in the near future. In the latest version, its weapon spacers are 3D printed out of Matterhackers NylonG because of its superior temperature and impact resistance. The 4 "teeth" on the weapon are 3/16" AR500.

Medium Rare has competed several times and won 1st place twice.

Weightclass: Antweight

Weapon: Wedge/Forks

Drive: 6 motor 6 wheel

Combat Record: 3-2

Achievements: 3rd place

Well Done

Well done is the first antweight robot that Repeat Robotics has fielded at a competition. It is a control style robot, with several attachments that it can use depending on its opponent. Well Done was originally designed as a mini-bot for a beetleweight competition, but has proven to be too slow to be effective.

Well done was designed to be as flat as possible, with a chassis only 14mm tall. It also utilizes magnets to create up to 3 pounds of downforce, giving it an effective weight of 4 pounds. The chassis is made from billet UHMW with a titanium bottom plate adding stiffness to the robot. The internals are held in place with mounts printed from NylonG. This robot uses Lego wheels to maintain superior grip on the floor, and it consistently dominated its opponents throughout the competition.

Weightclass: 300g

Weapon: Wedge/Plow

Drive: 4 motor 4 wheel

Combat Record: 6-1

Achievements: 1st place

Bricc mk2

BRICC Mk2 was designed to fix some of the problems that the original BRICC had. The main goal of the robot is to improve the internal layout and add wheelguards to the robot. Like the first version, BRICC Mk2 featured a billet aluminum chassis and 4 motor 4 wheel drive. This robot debuted at the October CHAMP competition and after losing the first fight, won the next 6 fights finishing in first place.

BRICC Mk2 had some control problems, which resulted in the drive system being weaker and harder to control than anticipated. These problems will be resolved before it fights again.

Weightclass: 300g

Weapon: Wedge/Plow

Drive: 4 motor 4 wheel

bricc mk1

BRICC Mk1 is a control robot that was designed to be as strong as possible. It has a billet aluminum chassis with foam four wheel drive. It also features Grade 5 titanium attachments. Due to a last minute electronics failure BRICC was unable to compete in the CHAMP competition, however it is now fully functional and ready to fight.

ablation OG

Ablation is the first robot that Repeat Robotics competed with. Ablation was designed for the CHAMP makerspace 300g robot battle. Ablation was designed to be completely 3D printed, with 7 chassis parts. It also featured a 3D printed hubmotor weapon design with a two tooth stainless steel weapon. Ablation had interchangeable front attachments between a wedge (for fighting horizontal spinners) and a pair of wedgelets, to get under other robots.

Ablation was mildly successful, both dealing and receiving a lot of damage, but was retired after just one competition due to some problems with the robot. The robot's frame was not strong enough to survive impacts, and due to it being several different parts it was very hard to work on.
